Avoid Mosquito Bites and West Nile Virus

When dealing with West Nile virus, mosquito bite prevention is your best bet. Fighting mosquito bites reduces your risk of getting West Nile virus, along with other illnesses that mosquitoes can carry. Take the commonsense steps below to reduce your risk:

Avoid mosquito bite
Clean out mosquitoes from the places where you live, work, and play
Help your community control the disease

Something to remember: The chance that any one person is going to become ill from a single mosquito bite remains low. The risk of severe illness and death is highest for people over 50 years old, although people of all ages can become ill.

Avoid Mosquito Bites

Use Insect Repellent Containing DEET
Apply insect repellent containing DEET (look for: N,N-diethyl-meta-toluamide) to exposed skin when you go outdoors. Even a short time outdoors can be long enough to get a mosquito bite. DEET is safe for pregnant and breastfeeding women and -- in concentrations of 10% or less -- in children.

Picaridin and oil of eucalyptus are newcomers to the mosquito repellent list. The U.S. Environmental Protection Agency approved their use in sprays and lotions in 2005. Studies show that both ingredients can help you guard against mosquito bites but because of their lower concentrations, highly concentrated DEET products will last longer.

Clothing Can Help Reduce Mosquito Bites
When possible, wear long sleeves, long pants, and socks when outdoors. Mosquitoes may bite through thin clothing, so spraying clothes with repellent containing permethrin or DEET will give extra protection. Don't apply repellents containing permethrin directly to skin. Do not spray repellent containing DEET on the skin under your clothing.

Be Aware of Peak Mosquito Hours
The hours from dusk to dawn are peak mosquito biting times for many species of mosquitoes. Take extra care to use repellent and protective clothing during evening and early morning -- or consider avoiding outdoor activities during these times.

Mosquito-Proof Your Home

Drain Standing Water
Mosquitoes lay their eggs in standing water. Limit the number of places around your home for mosquitoes to breed by getting rid of items that hold water, such as empty trash cans or unused children's toys.

Install or Repair Screens
Some mosquitoes like to come indoors. Keep them outside by having well-fitting screens on both windows and doors.

Help Your Community Fight West Nile Virus

Report Dead Birds to Local Authorities
Dead birds may be a sign that West Nile virus is circulating between birds and the mosquitoes in an area. More than 130 species of birds are known to have been infected with West Nile virus, though not all infected birds will die. It's important to remember that birds die from many other causes besides West Nile virus.

By reporting dead birds to state and local health departments, you can play an important role in monitoring West Nile virus. State and local agencies have different policies for collecting and testing birds.
