Mosquito Bite Prevention
Avoid Mosquito Bites
  • Be aware of peak mosquito hours - The hours from dusk to dawn are peak biting times for many mosquitoes. Consider rescheduling outdoor activities that occur during evening or early morning.
  • Clothing can help reduce mosquito bites - Wearing long-sleeves, long pants and socks when outdoors will help keep mosquitoes away from your skin.
  • Apply insect repellent when outdoors - Use a repellent with DEET (N, N-diethyl-m-toluamide), permethrin, picaridin (KBR 3023), oil of lemon eucalyptus [p-methane 3, 8-diol (p.m.D)] or IR3535 according to the instructions on the product label. DEET products should not be used on infants under 2 months of age and should be used in concentrations of 30% or less on older children. Oil of lemon eucalyptus should not be used on children under 3 years of age.
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 either draining or discarding items that hold water. Check rain gutters and drains. Empty any unused flowerpots and wading pools, and change water in birdbaths frequently.
  • Install or repair screens - Keep mosquitoes outside by having tightly-fitting screens on all of your windows and doors.
