Update - July 21 2021

With the return of warm temperatures coupled with drier conditions, the production of mosquitoes involved in the transmission of West Nile Virus (WNV) is on the increase. Our first WNV positive mosquito sample was found in mid-June. District monitoring of adult mosquito populations for WNV has found additional positive samples this week. While the risk of WNV transmission is still low at this time, amplification of WNV within the adult mosquito population is on the increase.

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.

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.


COVID-19 Statement

The Desplaines Valley Mosquito Abatement District (DVMAD) cares about the health and well-being of our residents and employees. Due to the COVID-19 pandemic, the DVMAD will be adapting operations to ensure we are providing service to the public in as safe and responsible a manner as possible. In order to comply with social distancing guidelines, we will be working with a reduced staff. While this will impact operations in many aspects, essential operations focusing on the monitoring and control of vector mosquitoes involved in West Nile Virus transmission to humans will remain unchanged.
