Prevent Mosquito Breeding:
While outdoors in an area with mosquitoes:
- Use a mosquito repellent. Repellents approved by the EPA include those containing DEET, oil of lemon eucalyptus, Picaridin or IR3535. Read the directions on the product label to find out about precautions that need to be taken and how long the product is effective.
- If you use a product containing DEET, do not use concentrations of more than 30% on adults and use low concentrations of DEET on children. Apply DEET to exposed skin (not eyes or mouth) and on clothes, but do not use on open cuts or wounds. Do not apply underneath clothes.
- Do not let children apply repellents to themselves. Apply the repellent to your hands and rub it on the child. Do not apply repellents to children’s eyes, mouth, or hands and use cautiously around ears. Do not apply DEET on infants (mosquito netting can be used over infant carriers) or oil of lemon eucalyptus on children under 3 years of age.
- When weather permits, wear protective clothing such as long sleeved shirts, long pants, and socks.
- Use air conditioning or window/door screens to keep mosquitoes outside. If needed, sleep under a mosquito bed net.
Mosquitoes need water to breed. Young mosquitoes (larvae) live in water before growing into adults that can fly. Items that collect water should be emptied at least once a week to prevent mosquito breeding.
- Containers: Turn over or cover unused flower pots, buckets, garbage cans, and wheelbarrows. Change water in birdbaths once a week.
- Gutters: Remove leaves and other debris that can clog gutters and trap water.
- Pools: Cover unused swimming pools and turn over kiddie pools when not in use.Be sure to keep swimming pool covers clear of leaves and water. Keep large pools treated and circulating.
- Old Tires: Cover or dispose of them. They are a favorite mosquito-breeding site.
