Fruit flies and gnats can be frustrating indoors, especially around houseplants, produce, and trash. The best indoor fly and gnat trap for your home depends on where insects gather, whether you prefer a plug-in light or a unit with a cord, and how often you want to replace sticky cartridges.

Our Picks: Best Indoor Fly And Gnat Trap reviews
1. Zevo Compact Flying Insect Trap: Best for Plants and Small Spaces
This compact plug-in trap is designed for spots where gnats and fruit flies often gather, such as beside houseplants, on shelves, or in a kitchen. Blue and UV light attracts flying insects to an adhesive cartridge, while a curved shield keeps the trapped insects out of sight.
The kit includes one base and three cartridges. The no-touch replacement design is useful if you would rather discard a covered cartridge than handle an exposed sticky card. It fits Zevo Compact and Zevo Plant refills, so you can look for compatible replacements when the included cartridges are used up.
Placement matters with this model. The product guidance recommends avoiding competing light from windows or grow lights for best results. Its compact size suits a single problem area, but it is not the best choice if you want a trap with a long cord for positioning farther from an outlet.
Pros:
- Compact plug-in form works well near plants and in tight spaces.
- Curved shield hides insects on the adhesive cartridge.
- Three cartridges are included with the base.
- Uses no sprays or insecticides and is described as safe around children and pets when used as directed.
Cons:
- Nearby windows or grow lights may compete with its light.
- Its plug-in design limits placement to locations near an outlet.
Verdict: Choose the Zevo Compact if you want a tidy, low-touch trap for a plant shelf, kitchen corner, or other small indoor area.
2. CHEER UPs Indoor Fly Trap: Best for Timer Settings
This indoor trap uses light and a sticky adhesive sheet to catch flies, gnats, and other flying insects. It is designed for locations such as kitchens, living rooms, and areas near plants, fruit, vegetables, or trash cans. Its compact housing takes up less space than a larger freestanding unit.
A useful difference is the choice between continuous operation and six- or twelve-hour timer settings. The trap connects using a USB cable and adapter, and its adhesive sheets are accessed through a bottom tray. The package includes ten glue boards, giving you replacements to use as the current sheet fills up.
The product description calls the operation low-noise and describes the control method as physical, with no odor. The trade-off is that this design uses exposed adhesive sheets rather than a cartridge that hides the catch. If you prefer not to see insects on a sticky surface, a shielded Zevo or Safer Home model may suit you better.
Pros:
- Offers continuous operation or six- and twelve-hour timer settings.
- Includes ten replacement adhesive sheets.
- Compact design is suited to indoor rooms and food-preparation areas.
- Described as low-noise, odorless, and safe around kids, pets, and food areas.
Cons:
- The adhesive sheet is exposed when the tray is open and needs changing.
- Requires a USB cable and adapter for operation.
Verdict: Consider this option if timer controls and a supply of replacement boards matter more to you than concealing the trapped insects.
3. LFSYS Fruit Fly Trap: Best for Extra Replacement Boards
The LFSYS trap pairs UV light with double-sided transparent adhesive boards. The product description lists two light wavelengths, 365 nm and 397 nm, and says the trap is intended to attract fungus gnats, fruit flies, and moths. The package includes one device and 11 refills.
Setup is simple: remove the protective film, place a board in the device, and plug it into an outlet. The adhesive is transparent and works on both sides, so insects remain on the board rather than inside a covered cartridge. You will need to check the trap and replace the board when it catches insects.
The manufacturer recommends using it in a dark room without other light sources for more effective trapping. That makes it a less convenient choice for a bright kitchen or a spot beside a grow light. Its quiet, odor-free operation may appeal if you plan to use a trap in a bedroom or other space where noise is a concern.
Pros:
- Includes 11 refill boards with the device.
- Double-sided adhesive provides trapping surface on both sides.
- Quiet, odor-free operation is suited to indoor use.
- Uses two listed UV light wavelengths to attract several types of flying insects.
Cons:
- The exposed adhesive board does not hide trapped insects.
- Its instructions recommend a dark room without competing light sources.
Verdict: The LFSYS is a practical pick if you want plenty of replacement boards and can place the trap in a dimmer area.
4. Safer Home Flying Insect Trap: Best for Flexible Outlet Placement
This plug-in trap uses UV LED light to attract fruit flies, gnats, moths, and other flying insects to a StickyTech glue card. Its compact design keeps the catch hidden from view, making it a discreet option for kitchens, bedrooms, or areas with houseplants.
The rotating plug is a useful design detail: it lets the unit fit standard outlets in different orientations. Setup involves inserting an included glue card and plugging in the trap. When the card is full, you will need to replace it with another compatible card.
Unlike the Zevo Compact, this model is described as using UV LED light rather than blue and UV light. It is a straightforward choice if you want a hidden glue card and a plug that can turn to suit your outlet. The supplied information does not specify how many replacement cards are included, so check the listing details if refill quantity is important to you.
Pros:
- Rotating plug can accommodate different outlet orientations.
- Compact housing keeps trapped insects out of sight.
- Uses UV LED light and replaceable StickyTech glue cards.
- Described as chemical-free and safe around children and pets when used as directed.
Cons:
- Requires replacement glue cards as they fill up.
- The supplied product information does not state the refill quantity.
Verdict: Pick the Safer Home trap if you want a simple, discreet plug-in model with a rotating plug for awkwardly placed outlets.
5. Zevo MAX Bug Catcher: Best for Larger Indoor Areas
The Zevo MAX is the larger option in this group. Its 360-degree blue and UV light attracts flying insects to an adhesive refill, and the product description says it can fit twice as many insects as the original Zevo Plug-In. A five-foot cord gives you more flexibility to position it near a kitchen, bathroom, garage, or plant area.
The kit includes one base and two cartridges. As with the Zevo Compact, the disposable adhesive backing is designed so you do not have to touch the trapped insects. The trap is made without insecticides and is described as safe around children and pets when used as directed.
The added coverage and cord make this model more flexible than a compact wall-plug trap, but it takes up more space and comes with fewer cartridges than the Zevo Compact. If you only need to target a small plant shelf, the smaller unit may be a better fit. For a larger area, the MAX’s wider light direction and cord may be more useful.
Pros:
- 360-degree blue and UV light is designed for larger indoor spaces.
- Five-foot cord allows more flexible placement.
- Adhesive refills keep trapped insects covered and out of direct contact.
- Includes one base and two cartridges.
Cons:
- Its larger format may be unnecessary for a small, focused problem area.
- Includes fewer cartridges than the Zevo Compact package.
Verdict: Choose the Zevo MAX if you need a corded trap for a larger room or want more flexibility than a direct plug-in design provides.
How to Choose an Indoor Fly and Gnat Trap
Match the trap to the problem area
Start by identifying where you see the most activity. A compact plug-in unit can suit a plant shelf or kitchen corner, while a model with a longer cord gives you more freedom to place it near an outlet-free spot. If insects appear in more than one room, you may need to move a trap or use separate units in different areas.
Choose a light and adhesive design you can live with
These products use light to attract insects and adhesive cards or cartridges to catch them. Some designs hide the catch behind a shield, while others use exposed sticky boards. A covered cartridge can feel tidier during replacement; a visible board lets you see when it needs changing. Consider which style you would rather maintain.
Think about room lighting
Other light sources can affect where you place a light-based trap. The Zevo Compact guidance recommends avoiding competing light such as windows or grow lights, and LFSYS recommends a dark room without other light sources. Consider a dimmer location where the trap’s light is less likely to compete with nearby sources.
Check the power and placement options
Direct plug-in traps are easy to set up but need an available outlet in the right location. A rotating plug can help with different outlet orientations, while a corded unit can be placed farther from the outlet. The CHEER UPs model uses a USB cable and adapter, so make sure that setup suits your space.
Compare refill supply and replacement steps
Refills are part of ongoing use, so check how many come in the package and whether replacements are easy to find. The listed bundles range from two cartridges for the Zevo MAX to 11 boards for the LFSYS trap. Also consider whether you prefer a no-touch cartridge or are comfortable removing and replacing an exposed sticky sheet.
Set realistic expectations
A trap can catch flying insects, but it does not remove the source that is drawing them indoors. For a more complete approach, look for and address likely sources such as ripe produce, food scraps, or persistently damp potting mix. Keep the trap in the area where activity occurs and follow the product instructions for placement and use.
Frequently Asked Questions
What is the difference between a plug-in trap and a corded trap?
A plug-in trap attaches directly to a wall outlet, which keeps setup simple but limits placement. A corded model, such as the Zevo MAX, can sit farther from the outlet. Choose based on where you need the trap and the outlets available in that room.
Where should I place an indoor fly and gnat trap?
Place it near the area where you notice flying insects, such as by plants or in a kitchen. Follow the product’s placement guidance, and avoid competing light sources where the instructions recommend it.
Do these traps use sprays or insecticides?
The listed traps work with light and adhesive cards or cartridges. The Zevo Compact is described as using no sprays or insecticides, and the Zevo MAX is described as being made without insecticides. Check each product’s instructions for its specific safety guidance.
How do I know when to replace a sticky card or cartridge?
Check the trap regularly and replace the adhesive when it has caught insects or is no longer usable. The LFSYS product description recommends checking its trap once a day; follow the instructions for whichever model you choose.
Are these traps silent?
The LFSYS and CHEER UPs descriptions specifically characterize their operation as quiet or low-noise. The other listed models use light and adhesive trapping, but the supplied information does not make the same noise claim for every product.
Will one trap solve a fruit fly or gnat problem?
A trap can catch flying insects, but it may not address the source of the problem. Check for food scraps, ripe produce, or other conditions that may be attracting them, and use the trap near the activity you want to target.
Final Recommendation
For most small indoor problem spots, the Zevo Compact is the most convenient starting point because it has a compact plug-in design, a covered cartridge, and three refills. Choose the Zevo MAX for more flexible placement in a larger area, the CHEER UPs model if timer settings matter, the LFSYS trap if you want a large supply of adhesive boards, or the Safer Home option for a discreet trap with a rotating plug.
