The best flying insect trap refills combine dependable device fit with a refill format that suits the insects and rooms you need to manage. My best overall pick is Zevo Flying Insect Trap Refill Cartridges, 4 Count for shoppers seeking a straightforward replacement from an established trap system. Raindot’s 16-pack for M364, M364A, and Max stands out for broader listed compatibility, while STEM’s insecticide-free cartridges suit buyers prioritizing that feature. The main tradeoffs are compatibility, refill count, and whether you want a cartridge or adhesive glue board. Read on for the full breakdown and guidance on choosing refills that fit your device and routine.

Key Takeaways
- Device compatibility is the first sorting step: several Raindot and Dickinda options name M364 and M364A models, while Raindot’s 16-pack also lists Max compatibility; those claims do not make the refills interchangeable with every trap.
- Multipacks serve different needs: Dickinda offers 10 cartridges and Raindot offers 16 for specified devices, while 40-count glue-board packs from Raindot and Shootingstar may appeal to homes that use compatible Safer Home traps frequently.
- Cartridges and glue boards are not the same refill: cartridge products such as Zevo and STEM are designed for their respective light-trap systems, while adhesive cards and boards require a matching card-style holder.
- Brand-specific options may simplify selection: Zevo, STEM, Ortho, and Safer Home refills make the most sense when their named device system is already in use, rather than as universal replacements.
- Pack size alone does not determine value: a larger count helps only when every refill fits the device and can be stored or used before adhesive performance declines.

More Details on Our Top Picks
Dickinda Flying Insect Trap Refill Cartridges, 10 Pack, Compatible with M364 and M364A
For owners of an M364 or M364A trap, Dickinda offers a straightforward way to keep that specific device supplied: the pack includes 10 odorless adhesive cartridges, and installation is a peel-and-insert job. That larger supply beats the four-cartridge Zevo MAX and standard Zevo refill pack for buyers who want fewer replenishment orders. The tradeoff is strict compatibility: these cartridges are replacement parts, not standalone traps, and the listed fit is limited to M364 and M364A models. Their small format also means they suit buyers replacing cartridges in an existing setup, not shoppers seeking a universal refill. I’d choose them when the model match is confirmed; otherwise, the more broadly described JIMMY’S GARDEN option may be easier to investigate, though its own compatibility details are vague.
Pros:- Ten cartridges provide a larger supply than the four-count Zevo MAX and standard Zevo pack.
- Designed for the M364 and M364A models.
- Odorless adhesive avoids adding a scent to indoor spaces.
- Peel-and-insert installation is simple.
Cons:- Cannot capture insects without a compatible trap.
- Compatibility is limited to the listed M364 and M364A models.
- Cartridges need replacement once the adhesive surface is covered.
Best for: Owners of M364 or M364A traps who want a 10-cartridge supply of odorless replacement adhesive.
Not ideal for: Buyers without an M364 or M364A trap, or anyone seeking a refill with broadly stated compatibility.
- Brand:Dickinda
- Compatible models:M364, M364A
- Pack size:10 cartridges
- Material:Odorless adhesive
- Dimensions:3.8 x 3.1 x 0.06 in
- Color:Blue
- Power source:None
Our verdict“Choose Dickinda if you have a confirmed M364 or M364A trap and want a 10-cartridge supply; skip it if your device model is different.”
Zevo Compact Flying Insect Trap Refills for Gnats and Fruit Flies, 6 Count
Zevo Compact and Zevo Plant owners get a refill designed for their specific indoor traps, with a covered, no-touch cartridge that keeps captured insects out of sight during replacement. That makes this a more discreet fit for kitchens or plant areas than a refill whose adhesive surface is exposed during handling. Its six-cartridge pack sits between Dickinda’s 10-count supply and the four-count Zevo MAX and standard Zevo pack, so it offers a moderate reserve rather than the largest quantity here. The key limitation is compatibility: these are not interchangeable with every Zevo trap. The light-based trap may also draw fewer insects when other bright light competes nearby. I’d pick this over Zevo’s four-count refill only if my device is a Compact or Plant model and hidden, hands-off disposal matters.
Pros:- Designed for Zevo Plant and Zevo Compact traps.
- Covered design hides captured insects.
- No-touch replacement avoids handling the adhesive surface.
- Six cartridges provide more replacements than the four-count Zevo MAX and standard Zevo pack.
Cons:- Compatibility is limited to Zevo Plant and Zevo Compact devices.
- Competing light sources can reduce attraction.
- Requires an electric trap device and cannot work on its own.
Best for: Zevo Plant or Zevo Compact owners who want discreet cartridge changes around kitchens, houseplants, or other indoor spaces.
Not ideal for: Owners of Zevo MAX, standard Zevo, or non-Zevo traps, and anyone who cannot limit competing light near the trap.
- Brand:ZEVO
- Compatible devices:Zevo Plant and Zevo Compact
- Pack size:6 cartridges
- Target species:Flies, fruit flies, gnats, and other flying insects
- Trap type:Blue and UV light
- Material:Plastic
- Item weight:2.88 ounces
- Model number:Model 6
- Manufacturer part number:ZEV-290446
Our verdict“Choose this six-pack for a Zevo Plant or Compact trap when hidden, no-touch replacement matters more than broad compatibility.”
Zevo Flying Insect Trap Refill Cartridges, 4 Count
For Zevo MAX and standard Zevo trap owners, this four-cartridge pack is the clearly matched replacement in this group. Its hidden adhesive surface keeps trapped insects out of view, while odor-free cartridges suit rooms where scented pest products would be unwelcome. Compared with the six-count Zevo Compact refill, this pack contains fewer cartridges but fits a different set of Zevo devices; the two are not interchangeable based on the listed compatibility. Dickinda supplies 10 cartridges, but only for M364 and M364A traps, so its larger count is no advantage to a Zevo owner. The main tradeoff here is a smaller pack and the need to buy compatible refills as the adhesive fills. I’d choose this for an exact device match, not as a general-purpose cartridge.
Pros:- Compatible with Zevo MAX and standard Zevo flying insect traps.
- Adhesive surface keeps captured insects out of view.
- Odor-free and made without added dyes.
- Designed for continuous day-and-night use.
Cons:- Only four cartridges are included, fewer than the six-count Zevo Compact pack.
- Requires a compatible Zevo trap and cannot be used independently.
- Cartridges need replacement when full.
Best for: Owners of Zevo MAX or standard Zevo indoor traps who want odor-free refills with captured insects concealed.
Not ideal for: Zevo Compact or Plant owners, users of other trap brands, and buyers seeking a larger refill quantity per pack.
- Brand:ZEVO
- Compatible devices:Zevo MAX and standard Zevo flying insect trap
- Pack size:4 cartridges
- Target insects:Flies, fruit flies, gnats, and other flying insects
- Material:Plastic
- Color:White
- Item weight:3.68 ounces
- Model number:Model 4
- Manufacturer part number:ZEV-018568
Our verdict“Pick this pack when you own a Zevo MAX or standard Zevo trap and want a discreet, odor-free refill that fits that device.”
JIMMY’S GARDEN Flying Insect Trap Refill Cartridges, 10 Count
JIMMY’S GARDEN is the broad-fit candidate in this group: its listing describes the cards for compatible plug-in flying insect traps and names flies, fruit flies, gnats, moths, mosquitoes, and other flying insects. The peel-off replacement format is simple, and the stated 10-count could make it appealing to buyers who need a larger reserve than the four-cartridge Zevo pack. But the compatibility language does not identify specific trap models, so it offers less confidence than Dickinda’s explicit M364/M364A fit or the model-specific Zevo refills. There is also a listing inconsistency: the title and unit count say 10, while the number-of-pieces field says 8. I’d treat this as a cautious option for owners able to verify dimensions and fit before choosing it.
Pros:- Adhesive surface is described for several types of flying insects.
- Peel-off replacement format is straightforward.
- Intended for indoor use across multiple spaces.
- The title and unit-count field state 10 cartridges.
Cons:- The listing does not name specific compatible trap models.
- Quantity information conflicts: 10 count in the title and unit count, but 8 pieces in another field.
- The trap device is not included.
Best for: Owners of plug-in flying insect traps who can confirm that these gray adhesive cards match their device and want a stated 10-count pack.
Not ideal for: Buyers who need confirmed model-specific compatibility or cannot resolve the listing’s conflicting quantity information.
- Brand:JIMMY’S GARDEN
- Listed unit count:10
- Number of pieces field:8
- Compatibility:Compatible plug-in flying insect trap devices
- Capture method:Adhesive sticky surface
- Intended use:Indoor
- Dimensions:1.3 x 0.37 x 5.8 in
- Color:Gray
- Model number:ZCB015
Our verdict“Consider JIMMY’S GARDEN only if you can verify the card fits your plug-in trap and are comfortable with the unclear quantity details.”
Husaco Flying Insect Trap Refill Cartridges, 6-Pack
Husaco’s stated target list covers gnats, flies, fruit flies, and moths, giving it a clear use case for buyers dealing with several common indoor flying pests. The six-cartridge pack is a middle ground between Dickinda’s 10-count M364/M364A option and Zevo’s four-count MAX and standard refill. Unlike those picks, though, Husaco gives a model name—HM364—without clearly listing compatible trap devices. That gap makes fit the deciding concern: I would check the trap’s cartridge dimensions and compatibility before ordering rather than assume a model match. The cartridges are reported to be easy to install and remove, but the listing does not say how long one lasts, so the pack’s practical service life is hard to estimate. Choose it only when compatibility can be confirmed.
Pros:- Targets gnats, flies, fruit flies, and moths.
- Includes six replacement cartridges.
- Designed for easy installation and removal.
- No power source is required for the refill itself.
Cons:- Compatible trap models are not clearly identified.
- No cartridge lifespan information is provided.
- Requires a compatible flying insect trap and cannot be used alone.
Best for: Owners who can verify HM364 cartridge compatibility and want six replacements for traps targeting gnats, flies, fruit flies, and moths.
Not ideal for: Buyers who need clearly named compatible devices or guidance on how often cartridges require replacement.
- Brand:Husaco
- Pack size:6 cartridges
- Target species:Gnats, flies, fruit flies, and moths
- Power source:None
- Dimensions:5.5 x 3.5 x 0.1 in
- Weight:0.13 kg
- Color:Blue
- Model:HM364
Our verdict“Choose Husaco only after confirming its HM364 cartridge fits your trap; otherwise, Dickinda’s explicit M364/M364A compatibility is a clearer choice.”
STEM Flying Insect Light Trap Refill Cartridges, Insecticide-Free, 6 Count
These six STEM cartridges suit households that want a straightforward, odorless refill for the STEM Light Trap without adding insecticide to their indoor pest-control routine. They are described for mosquitoes, gnats, moths, house flies, and fruit flies, giving them broader stated coverage than a refill aimed at just one pest type. Compared with the eight-count STEM pack, this option means buying refills sooner, but the two are designed for the same trap and insecticide-free use. The plug-in setup keeps operation simple, while the sticky surface still needs periodic replacement and the trap requires an outlet. Choose this pack when compatibility and a familiar, no-spray approach matter more than maximizing the number of boards in one purchase.
Pros:- Designed for the STEM Light Trap
- Insecticide-free and odorless
- Listed for mosquitoes, gnats, moths, house flies, and fruit flies
- Simple cartridge installation
Cons:- Six cartridges provide fewer refills than the eight-count STEM pack
- Requires a compatible plug-in trap and electrical outlet
- Sticky cartridges need periodic replacement
Best for: STEM Light Trap owners who want odorless, insecticide-free refills for a mix of indoor flying insects.
Not ideal for: People without a STEM Light Trap or an available outlet, and households seeking a larger refill supply per pack.
- Brand:STEM
- Unit count:6 cartridges
- Compatible device:STEM Light Trap
- Insecticide-free:Yes
- Intended use:Indoor flying insect control
- Target insects:Mosquitoes, gnats, moths, house flies, and fruit flies
- Model:STEM Light Trap
Our verdict“Choose this six-count pack if you already own the STEM Light Trap and want discreet, insecticide-free refills rather than the larger STEM pack.”
STEM Flying Insect Light Trap Refill Cartridges, 8 Count
For existing STEM Light Trap owners, this eight-cartridge pack offers more replacements in one purchase than the six-count STEM option. The added quantity can mean fewer replenishment orders, though the product data does not specify how long each cartridge lasts. These refills are insecticide-free and odorless, and are intended to capture mosquitoes, gnats, moths, house flies, and fruit flies indoors when used as directed. Unlike the Dichroma 24-pack, this is not a broadly compatible glue-board supply: it is made for one named trap system. That narrow fit is useful if you already own the STEM device, but a reason to skip it if you need generic boards or have another brand of trap. The trap itself is required and sold separately.
Pros:- Eight cartridges per pack
- Designed for the STEM Light Trap
- Insecticide-free and odorless
- Targets several types of common flying insects
Cons:- Requires a compatible STEM Light Trap, sold separately
- Not specified as compatible with other trap brands
- Per-cartridge use duration is not provided
Best for: STEM Light Trap owners who prefer a larger supply of compatible, odorless cartridges on hand.
Not ideal for: Buyers with BURLAN, Stingmon, Safer Home, DynaTrap, or other non-STEM traps, since these cartridges are specified for STEM Light Trap.
- Brand:STEM
- Unit count:8 cartridges
- Compatible device:STEM Light Trap
- Insecticide-free:Yes
- Intended use:Indoor flying insect control
- Target insects:Mosquitoes, gnats, moths, house flies, and fruit flies
- Manufacturer:SC Johnson
- Model:STEM Light Trap
Our verdict“Pick this over the six-count STEM pack if you own the matching trap and want more cartridges in one pack.”
Dichroma 24-Pack Flying Insect Trap Refill Sticky Glue Boards
The main advantage here is compatibility across several named traps: BURLAN QH009A, Stingmon, select Catchmaster Vector 9 models, and Wdoog. That makes the 24-board pack a more flexible choice than the STEM cartridges, which fit a specific STEM device. Each board is listed for use up to two weeks and can catch mosquitoes, fruit flies, gnats, and other small insects. The tradeoff is that compatibility is still limited to the models named, so buyers should match their trap carefully rather than assume these are universal glue boards. The trap is not included, and used boards need replacing. This is a practical pick when you own one of the supported models and want a powered-device-free refill surface, but not if you need STEM or Safer Home-specific sheets.
Pros:- Includes 24 sticky glue boards
- Fits several named indoor trap models
- Each board is listed for up to two weeks of use
- No power source is needed for the refill board itself
Cons:- Trap device is not included
- Compatibility is limited to listed models and select versions
- Boards require replacement after use
Best for: Owners of compatible BURLAN, Stingmon, Catchmaster Vector 9, or Wdoog traps who want a substantial board supply.
Not ideal for: STEM Light Trap and Safer Home trap owners, or buyers who have not confirmed their model appears in the compatibility list.
- Brand:Dichroma
- Unit count:24 boards
- Compatible models:BURLAN QH009A, Stingmon, select Catchmaster Vector 9, and Wdoog
- Use duration:Up to 2 weeks per board
- Target insects:Mosquitoes, fruit flies, gnats, and other small insects
- Color:White
- Item weight:0.17 kg
- Power source:None
Our verdict“Choose Dichroma if your trap is on its compatibility list and you want more flexibility than the STEM-specific cartridge packs.”
Raindot 40-Pack Fly Trap Glue Refills for Safer Home SH502, SH503, 23005-06, and DT3005W
Raindot supplies 40 adhesive sheets for several specifically named Safer Home and DynaTrap indoor models: SH502, SH503, 23005-06, and DT3005W. Its value is the pack quantity and tool-free replacement: peel the protective film and place a sheet in the compatible trap. That makes it a better fit for owners of those models than the Dichroma 24-pack, whose listed compatibility centers on different brands and devices. Each sheet measures 3.81 × 3.14 inches, so checking the trap’s fit is sensible before buying. Unlike the Shootingstar boards, Raindot does not provide a stated use duration, so replacement timing is less clear from the supplied details. The trap is not included, and the sheets are not a universal refill.
Pros:- Forty refill sheets in one pack
- Compatible with several named Safer Home and DynaTrap models
- No-tool installation by peeling and placing
- Specified sheet dimensions help buyers check fit
Cons:- Compatible trap is not included
- No use duration per sheet is specified
- Fits only the listed models
Best for: Owners of Safer Home SH502 or SH503 and the listed 23005-06 or DT3005W traps who want a large sheet supply.
Not ideal for: Buyers with STEM or other unlisted traps, or anyone who needs a clearly stated per-sheet service duration.
- Brand:Raindot
- Model:N-002
- Quantity:40 sheets
- Compatible models:SH502, SH503, 23005-06, DT3005W
- Sheet dimensions:3.81 × 3.14 inches
- Item weight:12.8 ounces
- Color:White
- Power source:Manual
Our verdict“Choose Raindot if you own one of its named trap models and prioritize a large supply over a stated board lifespan.”
Shootingstar 40-Pack Indoor Fly Trap Glue Board Refills
Shootingstar’s strongest differentiator is its stated up-to-three-week use duration per board, longer on paper than the two-week period listed for Dichroma’s boards. The 40-count pack also gives owners of supported Safer Home and DynaTrap traps a sizable supply. These paper boards fit SH502, SH503, DT3005W, and DOT 23005-06 models; remove the plastic cover and insert a board. That defined compatibility is useful, but it also rules out buyers with STEM or other unlisted devices. Compared with Raindot’s 40-sheet pack for overlapping models, Shootingstar provides a stated duration, while Raindot gives sheet dimensions and includes SH502/SH503 plus the same DynaTrap model names. The trap is not included, and boards still need replacement.
Pros:- Forty paper glue boards per pack
- Listed for up to three weeks of use per refill
- Compatible with specified Safer Home and DynaTrap models
- Simple insertion after removing the plastic cover
Cons:- Compatible only with the specified trap models
- Trap is not included
- Boards need replacement after use
Best for: Owners of the listed Safer Home or DynaTrap models who want a 40-board supply with a stated use period.
Not ideal for: People with unlisted trap models or buyers looking for universal refills rather than model-specific paper boards.
- Brand:Shootingstar
- Unit count:40 boards
- Material:Paper
- Compatible models:Safer Home SH502, SH503; DynaTrap DT3005W, DOT 23005-06
- Target species:Flies, mosquitoes, moths, and other small flying pests
- Recommended use:Indoor
- Color:White
- Potential use duration:Up to 3 weeks per refill
- Item weight:0.37 kg
Our verdict“Pick Shootingstar over Raindot if your compatible trap is listed and a stated up-to-three-week board life matters most.”
Zevo Flying Insect Trap Refill Cartridges, 1 Device and 3 Refills
This bundle is the practical pick for someone who needs a trap as well as refills: it includes one device and three cartridges, rather than asking buyers to source a compatible unit separately. Its stated target is gnats, which makes it a more focused choice than the Ortho Home Defense Max refills, whose listed targets also include fruit flies and house flies. The included cartridges give a new owner replacements on hand, but the product data does not specify how long each cartridge lasts or name the device’s compatibility beyond this bundle. That makes it harder to plan ongoing supply than with Ortho’s stated three-month coverage. Choose this Zevo pack for a straightforward start; skip it if you already own a different trap or need broad insect coverage.
Pros:- Includes a trap device, so buyers do not need to purchase a unit separately
- Three refill cartridges are included for follow-on use
- Specifically identifies gnats as the target species
Cons:- Less suitable for mixed pest concerns because the listed target is gnats
- Cartridge lifespan is not specified in the provided product data
- Includes a device, which may be unnecessary for existing trap owners
Best for: People dealing mainly with gnats who do not already own a compatible Zevo device and want initial refills included.
Not ideal for: Owners of another trap brand or buyers who need a refill-only pack with clearly stated replacement duration.
- Brand:ZEVO
- Pack contents:1 device and 3 refill cartridges
- Unit count:4
- Model number:Model 4
- Manufacturer part number:003
- Target species:Gnat
Our verdict“Choose this bundle if you need a gnat-focused trap and three refills, but pick Ortho for broader listed insect targets.”
Ortho Home Defense Max Indoor Flying Insect Trap Refills, 3 Cartridges
Among these four choices, Ortho gives the clearest match for households dealing with more than one kind of flyer: its cartridges are listed for gnats, fruit flies, and house flies. The pack contains three replacements for up to three months of protection, making supply planning easier than with the Zevo bundle, whose cartridge duration is not stated. That coverage depends on owning the Ortho Home Defense Max plug-in trap, which is sold separately; these are not standalone traps or universal glue cards. Compared with Raindot’s 16-pack, Ortho offers fewer cartridges and narrower stated compatibility, but its duration and target insects are spelled out. It suits current Ortho trap owners who want a simple, defined refill schedule, not shoppers seeking a high-count cross-compatible pack.
Pros:- Targets gnats, fruit flies, and house flies
- Three cartridges are stated to provide up to three months of protection
- Replacement cartridges are designed for simple swapping
Cons:- Requires the compatible Ortho trap, sold separately
- Intended for indoor use
- Limited to the listed Ortho device rather than multiple trap models
Best for: Owners of the Ortho Home Defense Max plug-in trap who want cartridges for several common indoor flying insects and a stated replacement window.
Not ideal for: Shoppers without the compatible Ortho trap, or owners of M364, M364A, or Safer Home devices.
- Brand:Ortho
- Model number:4663505
- Part number:4663505
- Quantity:3 refill cartridges
- Protection duration:Up to 3 months
- Compatible device:Ortho Home Defense Max Flying Insect Trap (sold separately)
- Target insects:Gnats, fruit flies, and house flies
- Intended use:Indoor
Our verdict“Pick Ortho if you already own its plug-in trap and want clearly specified coverage for several common indoor flies.”
Raindot Flying Insect Trap Refills, 16-Pack, Compatible with M364, M364A, and Max
Raindot stands out here for buyers who value a larger refill supply: its 16 sticky replacements outnumber the three-card Safer Home pack and the three-cartridge Ortho pack. The adhesive surface is listed for fruit flies, gnats, mosquitoes, and other flying insects, while the specified compatibility covers M364, M364A, and Max plug-in traps. That combination can suit households that already own one of those models and prefer to keep replacements ready. The tradeoff is fit: unlike a more narrowly matched brand refill, these cards are only described for the listed devices, so guessing at compatibility is a poor bet. They are also intended for indoor use. Check your trap model before buying; this is not a universal refill pack.
Pros:- 16 refills provide a larger stated supply than the three-card Safer Home and Ortho packs
- Compatible with M364, M364A, and Max plug-in traps
- Adhesive surface is listed for fruit flies, gnats, mosquitoes, and other flying insects
- Tool-free installation
Cons:- Compatibility is limited to the specified trap models
- Designed for indoor use
- The supplied product data does not state a replacement interval
Best for: Owners of M364, M364A, or Max plug-in traps who want a larger supply of indoor sticky refills for several types of flying insects.
Not ideal for: People with Ortho or Safer Home traps, anyone unsure of their trap model, or buyers seeking outdoor-use refills.
- Brand:Raindot
- Pack count:16
- Compatibility:M364, M364A, and Max plug-in insect traps
- Trap type:Sticky insect trap refill
- Intended use:Indoor flying insect trapping
- Color:White
- Item weight:1.6 ounces
- Power source:Hand-powered
Our verdict“Choose Raindot for a larger refill supply if your plug-in trap is one of the listed compatible models.”
Safer Home Flying Insect Trap Glue Card Refills, 3-Pack
Safer Home’s defining advantage is concealed capture: the glue cards are designed for the SH502 plug-in trap, which keeps caught insects hidden from view. That makes this a considered choice for indoor spaces where visible sticky boards would be unwelcome. Its cards target fruit flies, gnats, moths, and other flying insects, a broader stated list than Zevo’s gnat-focused bundle. The pack includes three cards, and the guidance is to replace each when full or every 30 days. Compared with Raindot’s 16-pack, Safer Home offers fewer refills and a tighter device match, but its stated interval helps set expectations. It is only a fit for the SH502, so buyers with other plug-in traps should check compatibility before ordering.
Pros:- Captured insects are hidden from view in the compatible trap
- Targets fruit flies, gnats, moths, and other flying insects
- Simple card insertion and replacement
- Replacement guidance is provided: when full or every 30 days
Cons:- Compatible only with the Safer Home SH502 plug-in trap
- Three cards make for a smaller supply than Raindot’s 16-pack
- Cards require regular replacement
Best for: SH502 owners who want indoor glue-card refills that keep captured insects out of view and have a stated replacement interval.
Not ideal for: People with a different trap model or buyers who want a larger refill pack or a cartridge lifespan beyond the stated 30-day guidance.
- Brand:Safer Home
- Model:SH503
- Quantity:3 glue cards
- Compatible device:Safer Home SH502 plug-in fly trap
- Technology:StickyTech adhesive cards
- Replacement interval:When full or every 30 days
- Intended use:Indoor flying insect control
- Target insects:Fruit flies, gnats, moths, and other flying insects
Our verdict“Pick Safer Home if you own the SH502 and value discreet capture over a high-count refill supply.”

I compared the 14 listings on the factors that matter most when buying replacement parts: stated device compatibility, refill format, pack size, and how clearly each product identifies its intended trap system. I gave preference to options with a specific fit or a recognizable device pairing, since a refill that does not seat properly can be less useful than a smaller, better-matched pack. I also distinguished glue boards from cartridges instead of treating all sticky refills as interchangeable.
The order reflects practical buying confidence and fit clarity, not an unsupported claim that one refill catches more insects than another. Brand-specific cartridges and clearly identified compatible packs rank ahead of broadly described alternatives; larger multipacks earn attention for repeat use, but not at the expense of compatibility. Product details supplied for this roundup do not establish comparative catch rates, adhesive lifespan, or independent test results, so I avoid ranking on those claims. Readers should confirm the trap’s model number and refill dimensions before ordering.
Factors to Consider When Choosing Best Flying Insect Trap Refills
Before choosing a pack, start with the trap already in your home. Refill listings can look similar while differing in cartridge shape, board dimensions, or device family, so the best purchase is usually the one that fits your holder and replacement habits—not simply the one with the highest count.
Match the Refill to the Exact Trap
Check the model number printed on the trap or its original packaging before comparing refill listings. A product title that names M364, M364A, Max, SH502, or another model is more useful than a vague claim of broad compatibility, but it still needs to match your exact device. Similar-looking cartridges can differ in their tabs, slots, or exposed adhesive area. Avoid assuming that refills from the same brand fit every model in its range. If a listing omits your model, compare the dimensions and attachment style or choose a refill explicitly listed for your trap. This small check can prevent a large multipack from becoming unusable.
Know Whether Your Trap Takes a Cartridge or a Glue Board
Cartridges and flat glue cards solve the same replacement need through different holders, and the terms are not interchangeable. Cartridge-based systems from brands such as Zevo and STEM need a refill shaped for that system; a stack of adhesive boards will not replace one unless the device is built for cards. Glue-board packs often list compatible model numbers, which should guide the choice more than a generic “indoor fly trap” label. Check how the old refill is removed and installed before ordering. If the replacement requires a different holder, account for that before treating a low refill count as a complete solution. Matching the format first narrows the field quickly.
Choose Pack Size Around Your Replacement Routine
A larger pack can reduce repeat orders, but it is only useful if the refills fit and you can store them properly. Think about how many traps you run and how often you replace a board or cartridge under your household conditions; the right interval can vary with insect activity and placement. For a single trap or occasional seasonal use, a smaller pack may be easier to manage. Frequent users may prefer a larger compatible pack, such as the 16- or 40-count options in this roundup, but should check the product’s storage guidance. Keep unused adhesive surfaces protected from dust and heat. Do not assume that the biggest count automatically gives the lowest cost per usable refill.
Check the Insects and Room You Need to Address
Some refill listings specifically name gnats and fruit flies, while others describe a broader flying-insect trap use. Use those descriptions as a starting point, then check the trap manufacturer’s guidance for the insects the device is intended to attract. A refill cannot correct a mismatch between the trap’s target and the pest causing the problem. Placement also matters: a kitchen trap may face different exposure to cooking residue or dust than one in a living area. Consider whether the device will sit near food-preparation spaces, pets, or children, and follow the trap and refill instructions for placement and handling. Choose claims and formats that fit your actual setup rather than relying on a broad label.
Weigh Insecticide-Free Preferences Against System Fit
If avoiding insecticide is a priority, look for an explicit product statement such as STEM’s insecticide-free label and verify the details on the current package. Do not infer that every adhesive refill has identical materials or handling instructions simply because it catches insects with a sticky surface. System compatibility still comes first: a refill with a preferred feature is not a practical choice if it does not fit your trap. Read the manufacturer’s instructions for disposal and placement, especially in rooms used by children or pets. When comparing options, separate the feature you want from claims the listing does not establish. That keeps a preference from becoming an assumption about safety or performance.
Treat Replacement Frequency as a Home-Specific Decision
There is no single refill interval that fits every home, because dust, humidity, insect traffic, and trap location can affect how long an adhesive surface remains useful. Follow the device maker’s replacement guidance and inspect the board or cartridge for visible coverage or debris. A refill that still has exposed adhesive may be usable, while one coated in dust or insects may need changing sooner. Avoid stockpiling more than you can store in clean, dry conditions. If you are unsure how quickly a trap will use refills, begin with a smaller compatible pack and adjust your next order based on actual replacement frequency. That approach limits wasted refills without guessing at a universal schedule.
Frequently Asked Questions
How can I tell whether a refill fits my flying insect trap?
Find the trap’s model number on its label, manual, or original packaging, then compare it with the refill’s compatibility list. Check the refill format and dimensions too: a cartridge may use a different attachment from a flat glue card, even when both are marketed for flying insects. Do not rely on brand name alone, since product families can have multiple device designs. If the model is not listed, confirm the fit with the manufacturer rather than guessing from appearance. This matters most when ordering a large multipack.
Are Zevo, STEM, Ortho, and other brand refills interchangeable?
Do not assume they are interchangeable. Each system may use a cartridge or board with its own shape and holder, and a refill must fit securely to work as intended. The product names in this roundup identify brand-specific systems, not a shared universal standard. Compare the exact trap model and refill style before substituting another brand. If compatibility is not clearly stated, a refill listed for your device is the safer choice.
Should I buy a large refill pack or start with a smaller one?
A large pack is a better fit when you already know the refills match your trap and you replace them regularly. If you are trying a new format, device, or compatible brand, a smaller pack limits the chance of being left with unusable stock. Storage also matters: adhesive surfaces should stay protected from dust and other conditions named by the manufacturer. Consider the number of traps in use and your usual replacement pace rather than choosing by count alone. The 40-count board packs are most relevant to repeat users with compatible holders.
Can I use glue-board refills in a cartridge-style trap?
Only if the trap is designed to accept that specific board format. A flat glue board generally cannot substitute for a cartridge simply because both use adhesive to catch insects; the holder, size, and exposed surface may differ. Check your device instructions and the refill’s compatibility list before attempting a swap. For this roundup, the Zevo and STEM cartridge listings should be treated as system-specific, while board products identify their own compatible traps. A proper fit avoids wasted refills and keeps the device assembled as intended.
Does an insecticide-free refill mean I can place the trap anywhere?
No. An insecticide-free label describes a product feature, not permission to ignore placement or handling directions. Follow the trap maker’s instructions, and consider exposure to children, pets, food-preparation areas, dust, and moisture. The trap’s light or electrical components may also affect where it should be positioned. Check the current package for disposal guidance and any use restrictions. If placement advice is unclear, consult the device manufacturer before setting it near sensitive areas.
Conclusion
For most shoppers, I would start with Zevo Flying Insect Trap Refill Cartridges, 4 Count as the best overall choice when the matching Zevo trap is already in use. For best value by pack size, compare Dickinda’s 10-pack or Raindot’s 16-pack only if your M364-family device matches the listed compatibility; regular Safer Home users can look at Raindot or Shootingstar’s larger board packs. STEM’s insecticide-free cartridges are the best fit for buyers who specifically want that stated feature, while brand-matched Zevo, Ortho, or Safer Home refills are the simplest route for beginners who want to avoid format guesswork. For specific needs, choose compact Zevo refills for a compatible compact system and glue cards for a trap designed to hold boards. My final rule is simple: confirm the model and refill format first, then choose the pack size that suits your replacement routine.
