Recent heavy rains combined with warm temperatures will result in a major hatch of the Aedes vexans floodwater mosquito, as reported in a Desplaines Valley Mosquito Abatement District (DVMAD) press release. The Aedes vexans floodwater mosquito is not involved in disease transmission but it is an aggressive biter with a flight range over 10 miles. Residents can expect a noticeable increase in adult mosquito annoyance within the next week due to adult mosquito migration.
While nuisance mosquitoes will be the predominant species present, residents are cautioned that the mosquito species involved in West Nile Virus (WNV) transmission is also present. The risk of WNV transmission is low, but individuals are still encouraged to use a commonsense approach in avoiding exposure to mosquitos. To prevent mosquitos from entering the home any damaged window screens, openings around window air conditioners or clothes dryer vents should be repaired or eliminated. If possible, limit outdoor activity at dusk, and 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.
Individuals should look for potential mosquito breeding sources around the home and take the following simple steps:
- Throw away all trash that can hold water as cans, jars, bottles, etc.
- Clean rain gutters/downspouts to prevent water from standing in gutters or on flat roofs.
- Change water in bird baths, wading pools, etc. at least once a week.
- Maintain swimming pools properly.
- Remove or turn over containers, buckets, wheelbarrows, etc. which may accumulate water.
- Screen rain barrels to prevent adult mosquitoes from depositing eggs on the water’s surface.
- Aerate ornamental ponds and stock with goldfish or other surface-feeding fish to control mosquito production.
