Mosquitoes in the House
Pest management companies get many questions from customers about mosquitoes in houses. These inquiries range from how the pests get inside to what issues they cause indoors. The answers to some of these questions can help with mosquito prevention and control.
Identifying Mosquitoes in the House
Why Are There Tiny Mosquitoes in My House?
Insects can be difficult to identify since they are so small. In the U.S., most adult mosquitoes are about 0.2 to 0.35 inches in length. What people call tiny mosquitoes in the house may actually be midges, gnats, and other small, non-biting and biting pests. Anything from uncovered trash, excess moisture and lights may draw these insects indoors.
Why Are There Big Mosquitoes in My House?
Crane flies look like extra-large mosquitoes. Light is a strong attractor for these pests, which is why crane flies often fly into homes.
Additionally, some mayfly species breed in the same habitats as mosquitoes, so residents may mistake them for a bigger version of these pests. Neither mayflies nor crane flies bite or spread disease, but they sure can be an annoying nuisance.
How Do They Get Inside?
Where Are They Coming From?
These insects like cool, shaded spaces and can get indoors rather easily. A few ways that mosquitoes can enter homes during the day or night are through:
Poorly sealed windows
Where Do They Lay Eggs?
If there are regularly mosquitoes in the house, check outside for anything that could hold water. These pests lay their eggs in pools of water outside the home.
Remove anything unnecessary and drain the remaining containers as soon as possible after rain showers. Various outdoor items that collect water where these pests lay eggs are in:
Why Are Mosquitoes in My House Plants?
Overwatering plants can lead to a mosquito problem. The insects only need a small amount of water to lay eggs, which means that they can even breed in the overflow that seeps into the pot saucer of a planter. When the larvae fully develop and the winged adults emerge, people may see mosquitoes resting in their house plants or actively flying around while attempting to locate residents and/or their pets to feed on.
Why Are Mosquitoes in My House During Winter?
Once temperatures fall below 50 degrees, female mosquitoes stop biting. Although some species die off in the fall, others hibernate in winter. On unseasonably warm days, mosquitoes may temporarily become active, but once the weather cools they will once again return to overwintering sites.
How to Get Rid of Them
While insect sprays and foggers are effective, using them inside a home without carefully following the use directions on the product label can be unsafe.
