Across a yard of up to ¾ acre, the DynaTrap DT160 mosquito trap cuts down mosquito and other flying insect populations. Bob Vila's review praised the weather-resistant design and easy assembly, and reported catches of flies and moths alongside mosquitoes. Reviewers also noted it doesn't kill what it catches, so insects can escape while you empty it, and it may take beneficial pollinators with them. At 25 inches tall and 15 inches in diameter, it is hard to hide in a landscape. It fits people who want comprehensive, non-chemical pest control, and not those worried about pollinator impact or short on space.

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

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

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.
