Summertime and early autumn means a host of fun outdoor activities, but it can also mean mosquito bites. Mosquitoes can spread diseases including eastern equine encephalitis (EEE) and West Nile virus (WNV). The best way to prevent these diseases is to prevent mosquito bites and reduce breeding areas on your own property.
During risk periods of WNV or EEE, residents should take preventative actions to avoid mosquito bites.
- Be aware that mosquitoes are active in damp shady areas, during cloudy humid days, at dusk, dawn and during the night.
- To protect yourself from mosquitoes use mosquito repellent and wear protective clothing. Use repellents containing DEET, Picaridin or Oil of Lemon Eucalyptus and follow the directions on the label. Never use DEET on infants. Oil of Lemon Eucalyptus should not be used on children under three. Although uncomfortable during hot days, long-sleeve shirts and long pants can provide a layer of protection.
- Cover up the arms and legs of children playing outdoors. Baby carriages and playpens should be covered with mosquito netting.
- Fix any holes in screens and screen doors and replace worn weather stripping.
There are certain actions that residents should take related to WNV.
- To prevent a yard from becoming a source for Culex mosquitoes, homeowners should make a thorough inspection of their property and remove, empty, cover or treat any water-holding containers. During the summer, mosquito larvae can complete their development in water within a week.
- Containers where mosquitoes commonly lay eggs include neglected swimming pools, water in loose fitting pool covers or tarps, unscreened rain barrels, rimless tires, and plastic toys.
- Tires should be disposed of properly or stored inside.
- Rubbish barrels, wheelbarrows and small boats should be covered or stored upside down.
- The water in wading pools and birdbaths should be changed weekly.
- Infrequently used pools should be covered or properly maintained.
- Rainwater collection barrels should be screened, emptied once a week or treated with products containing Bti.
