Control Mosquitoes Around The Home

A mosquito will lay its eggs in discarded tires, unwashed bird baths and clogged rain gutters

Did You Know?

In 2005, for the first time in Idaho, mosquitoes tested positive to the disease West Nile Virus. The mosquitoes that tested positive were found in Canyon County. 

It is possible to generate large amounts of mosquitoes around the home with small amounts of water. Mosquitoes can have many generations in one year, and in the heat of summer, they can emerge from egg to adult in about a week.

The northern house mosquito, Culex pipiens, is the most common mosquito found around the home and is a primary carrier of West Nile Virus. This mosquito will lay its eggs in any receptacle containing water rich in decomposing organic material such as discarded tires, unwashed bird baths, clogged rain gutters and plastic wading pools allowed to stagnate through disuse. The best way to prevent mosquito production is to remove any objects that hold water from your yard.

A mosquito will not lay eggs in water if it is too clean. Grass clippings, dead leaves, etc. quickly produce a mix that is highly attractive to the female mosquito. Once the water begins to foul, the mosquito will lay eggs in any receptacle containing decaying organic material found on your property.


Avoid Collecting Standing Water

  • Rain gutters on houses tend to fill up with leaves and other things that clog the gutters.
  • Swimming pools can produce ample mosquitoes to bother a neighborhood. Keep pools full of clean water and clean out algae and leaves. Pool covers can also hold mosquitoes. Some mosquito larvae hatch out in March, so covers should be removed and the pools filled with chlorinated water as soon as practical in the spring.
  • Tires are notorious for producing large numbers of mosquitoes. Store tires in a shed or garage. If you have a tire swing, drill a hole in the bottom so it cannot hold water.
  • Flower pots and drain dishes underneath the pot can hold enough water to produce mosquitoes.
  • Garbage/recycling containers can collect water. Place drainage holes in the bottom of garbage cans or recycling containers.
  • Tarps are used to cover items such as wood, boats, etc. Always keep the tarp tight and drain any water off the tarp. Any depressions in a tarp can hold enough water to produce mosquitoes.
  • Boats: The plug in the bottom of the boat should be open so water can drain from it. Store boats in the garage or turn them over so they cannot hold any water.
  • Buckets, soda cans, birdbaths, and watering troughs can also collect standing water.


Keep Mosquitoes from Entering Your Home

  • Seal gaps and weather-strip doors.
  • Repair or replace window screens.


Water Trees, Shrubs, and Lawns Properly

The following schedule is recommended by the University of Idaho in reference to landscape and turf at 1/2 inch of water per irrigation cycle.

April...........Once every 7 days
May............Once every 4 days
June & July..Once every 3 days
August........Once every 2 days
September...Once every 6 days
October.......Once every 12 days

Over-irrigating can lead to tremendous hatch-offs of mosquitoes that can affect a whole neighborhood. Over-irrigating can also lead to fungal and other plant-related disease or insect problems.
