2025 Mosquito Season Update - July 9th
Current warm temperatures coupled with drier conditions have increased the production of mosquitoes involved in the transmission of West Nile Virus (WNV). WNV positive mosquito samples have been found in our area, however at levels where the risk of WNV transmission is still low at this time. While this is not unusual for this time of year, WNV levels within the adult mosquito population are expected to increase as the summer progresses.
Residents are encouraged to use a common-sense approach in avoiding exposure to adult mosquitoes and any potential mosquito-borne diseases. Window screens should be inspected and repaired if damaged to prevent mosquitoes from entering the home. In addition, any openings around window air conditioners, clothes dryer vents, etc. should be eliminated for the same reason. If possible, avoid outdoor activities around dusk. If not possible, wear shoes, socks, long pants and a long-sleeved shirt. Loose-fitting, light-colored clothing is best. Appropriate use of insect repellents per manufacturer’s instructions is recommended.
Crews have been actively treating stormwater catch basins located both on roadways and in off-road areas (parks, apartment complexes, etc.) along with routine inspection/treatment of all other potential mosquito breeding sources to prevent the emergence of adult mosquitoes from their aquatic stage of development since the start of May.
Residents should look for potential mosquito breeding sources around the home and take the following simple steps:
1) Throw away all trash that can hold water as cans, jars, bottles, etc.
2) Clean rain gutters/downspouts to prevent water from standing in gutters or on flat roofs.
3) Change water in bird baths, wading pools, etc. at least once a week.
4) Maintain swimming pools properly.
5) Remove or turn over containers, buckets, wheel barrows, etc. which may accumulate water.
6) Screen rain barrels to prevent adult mosquitoes from depositing eggs on the water’s surface.
7) Aerate ornamental ponds and stock with goldfish or other surface-feeding fish to control
mosquito production.
8) Dispose of any used tires without rims to prevent water accumulation.
