Ranked #3 in Best Bug Zappers

Katchy Indoor Insect Trap

4.3

4 sources2 derived$44.99as of Aug 1

UV light and fan suction make the Katchy Indoor Insect Trap a non-toxic, child-safe way to handle flying pests like fruit flies, gnats, and mosquitoes. Reviewers say it performs best at night with the lights off, when its UV is the brightest source in the room. The manual model is simple but needs your attention; the automatic version switches on when it detects darkness. The newer Katchy Duo adds a scented bait pod for daytime effectiveness, though information on replacing the bait is thin. Small insects are its range, and large house flies get past it. Good for indoor pest control, not a complete answer to a severe infestation.

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

4 sources3 derived$19.98as of Aug 1

The Zevo Flying Insect Trap does not zap. Blue and UV light draw flying insects onto a disposable adhesive cartridge behind a curved shield, silently and without chemicals. Wirecutter's Elissa Sanci cleared a garage fly problem with one overnight run; Bob Vila's week-long trial caught a steady handful of fungus gnats and fruit flies a day in a house with no visible infestation. It is a targeted tool for a kitchen, bathroom or plant corner rather than a whole-home answer, and it needs a fresh cartridge on a schedule.

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

— Non-selective: moths and other harmless flying insects end up on the cartridge
— Bright ambient light competes with the lure, so it does most of its work overnight
— Cartridges are a recurring cost and need changing sooner in a busy room

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.
