Press Release - 07/08/20

Although levels of WNV (West Nile Virus) within the mosquito population are still low, with the return of warm temperatures, conditions are ideal for the increased production of the mosquito species involved in WNV transmission and the subsequent WNV amplification cycle within the adult mosquito population.

District mosquito larval control operations are aggressively inspecting/treating potential breeding sources to minimize adult mosquito development. The District encourages residents to look for potential mosquito breeding sources around the home, and take the following 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.

Anything that can hold enough water can breed mosquitoes.

The species of mosquito involved in WNV transmission is a passive mosquito, and not an aggressive biter with its presence often undetected. Residents are encouraged to use a common sense approach in avoiding exposure to adult mosquitoes and any potential mosquito-borne diseases. If possible, avoid outdoor activities around dusk. When 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 to minimize mosquito bites.

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.

The District actively monitors adult mosquito populations for the presence and level of WNV. This season, the District is moving to the PCR (polymerase chain reaction) platform for testing mosquito samples for WNV. PCR testing provides a greater sensitivity in detecting virus presence, and will give earlier indication of WNV amplification within the vector mosquito population.

COVID-19 Statement - 05/01/2020

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.
