One of the best known summer pests, mosquitoes breed in stagnant water or soft soil and can develop from egg to adult in 10 to 14 days.

Can transmit West Nile encephalitis, a sometimes fatal inflammation of the brain.
Acquire the West Nile Virus from infected birds.
Breed in stagnant or putrid water. Mosquitoes are unlikely to breed in clear, clean water such as a well maintained swimming pool.
Are effectively repelled by products containing DEET (N,N-diethyl-meta-toluamide).

Female mosquitoes suck our blood. Male mosquitoes feed on plant nectars. They can develop from egg to adult in 10 to 14 days. They are most active from dusk to dawn and will fly up to 14 miles for a blood meal.


Mosquitoes breed in stagnant water sources such as storm drains, old tires, children's wading pools and birdbaths.


Mosquitoes are well-known to spread diseases such as West Nile Virus, malaria and dengue fever.

Prevention
Eliminate or reduce mosquito breeding sites by replacing all standing water at least once a week. This includes bird baths, ponds and unfiltered pools. Remove unneeded vegetation or trash from around any standing water sources that cannot be changed, dumped or removed. Introduce mosquito-eating fish such as gambusia, green sunfish, bluegills and minnows to standing water. Screen windows, doors and other openings with mesh. Avoid going outdoors when and where mosquitoes are most active: during dusk or dawn. Use insect repellent containing DEET on exposed skin whenever or wherever mosquitoes are likely to bite.
