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.


The Hausbell indoor trap is USB powered, eco-friendly and safe for children and pets. It features has a quiet night light, 360 degree suction and a removeable catch cage for cleaning. manual or automatic mode of operation.

Simple and effective, the Hausbell is an indoor trap that kills mosquitos and other flying insects. Compact, lightweight and chemical-free by design, this trap is also easy to clean.

It can optionally be used with a mosquito lure (not included)


Like all the DynaTraps, the indoor DT250IN uses a combination of light, heat and safe CO2 (generated by a titanium dioxide coating) to attract and catch mosquitoes. A quiet vacuum fan sweeps them into a well-designed, escape-proof catch bin.

The DT250IN features a 7 watt uv light (rated at 3000 hrs), a cleaning brush and a 7' cord. It covers areas up to 1000 sq feet and comes with a 1 year warranty.

The indoor DynaTrap DT250 uses a proven combination of safe attractants and an effective capture system to lure and trap mosquitoes and other flying insects. We wish the cord was a tad longer.

Overall we like DynaTrap products - they're effective and sensibly priced - but you will find yourself going through bulbs pretty quickly. Invest in a replacement bulb or two so you're not caught unprepared.


Attracts and catches flying insects using heat, UV light, safe CO2 and vacuum fan. The quiet DT500IN uses 2 7 watt UV bulbs (rated at 3000 hours each). The 7' cord plugs into any standard 120V outlet. Covers areas up to 1290 sq ft. - ideal for garages, work areas, barns. Cleaning brush and optional wall-mount bracket is included. Comes with a 1 yr warranty.

Uses the same strategies as the DT250, but with a slightly different design. Can be wall-mounted, or simply placed on a table or counter top. For a wall-mounted product, we think a 7' cord is a little stingy - you may need an extension cord.

As with all DynaTraps, keep a couple of replacement bulbs handy so you're good to go if the others burn out.


Attracts and traps mosquitos without using propane or expensive lures.

We're not sure if this is genius or madness. Instead of using fancy chemical lures, the Mosquito Defeato trap, by Empirical Systems LLC, attracts mosquitos by using ... your own sweaty clothing.

While this may seem a little odd, it is probably very effective, as this scent is exactly what mosquitos are looking for.


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.
