Indoor Mosquito Traps

Mosquito traps for indoors are helpful as long as you use them properly and understand their limitations. They're great for a quick "cleanup" but aren't going to solve a stubborn infestation.

If mosquitoes have been getting in and buzzing around your house, you probably know from experience that it's not easy to find them before they find you. They're small, hard to see, and unpredictable. Not to mention, sneaky. You'll be blissfully unaware of them until you catch one feasting on your arm!

This is where an indoor insect machine can come in handy. Place it in a room, turn off the other lights, close off the area and leave. That last step is key - if you stay in the area, they're likely to pass up the trap and head straight for you.

Let the trap do its thing for at least a good hour or so. When you return, anything that was flying around in that room should have found its way into the trap.

What you catch indoors won't make a dent on the mosquito population outdoors. If you have a hole in your window screen or gaps around your door, or kids who leave doors open when they go in and out to play, the rest of the mosquito family will be sending in reinforcements as fast as you can catch them. Buy or repair screens, caulk openings, replace worn weatherstripping, have a talk with your kids.

The best permanent results come from addressing the problem outside, where the insects live, but an indoor mosquito catcher can help make life inside more bearable in the meantime.

Unlike the other Dynatrap products, the DT3000 series uses glue cards instead of a catch net to capture insects. They provide coverage for up to 600 sq feet.

Optional features: 2 outlets (DT3019) or 2 outlets and 2 USB ports (DT3039).

These plug-in insect traps use Dynatrap's AtractaGlo UV lighting to draw insects to a replaceable StickyTech card, hidden behind a decorative panel. This is a time-proven way to catch insects with no mess and no risk of live insects escaping from the trap. Simply replace the card every 30-60 days or as needed.

Don't want to give up your electrical outlets? This trap is also available with 2 pass-through A/C outlets or with 2 outlets and 2 USB ports.


Quiet operation. Pesticide and odor free. Protects up to 300 sq feet.

Weighing just over 1 lb, the DT150 uses the DynaTrap 3-way system - UV light, heat and carbon dioxide - to lure mosquitoes, stink bugs, biting flies and more into the unit, where the fan pulls them into the catch bin in the base to dehydrate and die.

The bulb in the DT150 is rated for 20,000 hours of use and is not replaceable.
