Ranked #6 in Best Bug Zappers

DynaTrap DT160 Mosquito Trap

3.8

$175

The DynaTrap DT160 mosquito trap effectively reduces mosquito and other flying insect populations in yards up to ¾ acre. Bob Vila's review praised its weather-resistant design and ease of assembly, noting it successfully captured various pests including flies and moths. However, reviewers also pointed out that the trap doesn't kill insects, potentially allowing escapes during emptying, and may unintentionally capture beneficial pollinators. The trap's large size (25 inches tall, 15 inches diameter) may detract from landscape aesthetics. This device is best suited for those seeking a comprehensive, non-chemical pest control solution but may not appeal to users concerned about pollinator impact or those needing a compact option.

Strengths

— Easy assembly with simple twist-on motion for attaching the bug-catch basin
— Weather-resistant construction withstands rain and windy conditions
— Covers up to ¾ acre area for extensive protection against flying pests

Watch-outs

— Does not kill captured insects, which may lead to escaping insects during emptying
— May inadvertently capture beneficial pollinators like honey bees

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

How they stack up

DynaTrap DT160 Mosquito Trap

The DynaTrap DT160 provides extensive outdoor coverage up to ¾ acre, which far exceeds the indoor-focused Katchy trap and Zevo trap. However, unlike the Flowtron FC4700 which offers silent low-voltage stunning, the DT160's fan-based trapping may be noisier. The DT160's weather-resistant design makes it superior to the Aspectek zapper for outdoor use, but it doesn't kill insects like the Flowtron models do, and it may inadvertently capture beneficial pollinators.

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.
