Ranked #3 in Best Bug Zappers

Katchy Indoor Insect Trap

4.3

$29

The Katchy Indoor Insect Trap offers a non-toxic, child-safe solution for controlling flying pests like fruit flies, gnats, and mosquitoes using UV light attraction and fan suction. According to reviewers, it works best at night when lights are off and the UV light is the brightest source. The manual model is simple but requires user attention, while the automatic version turns on when darkness is detected. The newer Katchy Duo adds a scented bait pod for daytime effectiveness but lacks clear information on bait replacement. While effective for smaller insects, it doesn't catch large house flies. This trap is ideal for indoor pest control but not a complete solution for severe infestations.

Strengths

— Uses UV light to attract insects and fan suction for effective trapping
— Child-safe and non-toxic with no insecticides or toxic substances
— Compact design at 5.5 inches wide and 9 inches tall, weighing only 1.4 pounds

Watch-outs

— Does not trap large house flies or other large insects
— Manual models require user to remember to turn on/off or leave on all day
— Sticky paper needs regular replacement and can be messy to handle

Zevo Flying Insect Trap

4.4

$19

The Zevo Flying Insect Trap offers a quiet, chemical-free alternative to traditional bug zappers, using blue and UV light to lure insects into disposable adhesive cartridges. Wirecutter's Elissa Sanci found it highly effective in eliminating a garage fly infestation, while Bob Vila's review praised its ease of use and mess-free maintenance. However, reviewers noted the traps are best suited for small, contained areas like kitchens or plant rooms, and may catch non-target insects such as moths. The traps work best overnight and require regular cartridge replacement, making them ideal for targeted pest control rather than whole-home solutions.

Strengths

— Uses blue/UV light to attract insects without loud zapping or sparking
— Ultra-sticky adhesive cartridges effectively catch flying pests like gnats and fruit flies
— Easy, mess-free cartridge replacement process with no contact with dead insects

Watch-outs

— Limited coverage area, not suitable for large open spaces
— Catches non-target insects like moths alongside flies
— Requires frequent cartridge replacement depending on insect activity

How they stack up

Katchy Indoor Insect Trap

Unlike the DynaTrap models which suffer from frequent build quality issues and fan failures, the Katchy Indoor Insect Trap offers a simpler, more reliable design with UV light and fan suction. While the DynaTrap DT3007W provides 24/7 LED trapping, the Katchy is more effective against smaller insects like fruit flies and gnats but lacks the power to tackle large house flies that the Flowtron FC4700 can handle. The Katchy's manual operation is a drawback compared to the automatic DynaTrap models, but it's more child-safe than the Aspectek zapper.

Zevo Flying Insect Trap

The Zevo Flying Insect Trap uses ultra-sticky cartridges which are easier to replace than the DynaTrap DT3007W's glue cards, but unlike the Katchy trap, it's more effective against gnats and fruit flies. The Zevo's blue/UV light is quieter than the Aspectek's sparking grid, but the Aspectek's 2,800 volts provide more immediate results. The Zevo is less effective than the Flowtron FC4700 for larger insects, but it's more suitable for small indoor spaces.
