Mosquito Season Update - June 26th, 2026
Recent heavy rains combined with warm temperatures is resulting in a major brood of the Aedes vexans floodwater mosquito in time for the Fourth of July holiday. This mosquito is not involved in disease transmission, however is an extremely aggressive biter active day and night. This mosquito is migratory by nature, with a flight range of well over 10 miles. Although District larval control operations addressed mosquito production in our area, 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 in our area. This species is not an aggressive biter with limited flight range, however must not be forgotten. Above normal positive adult mosquito samples for WNV have been found within the District this season. While this is not unusual for this time of year, it does indicate that WNV is increasing and residents need to use precautionary measures.
Residents are encouraged to use a common-sense approach in avoiding mosquito bites and 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, such as DEET or Picaridin, 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. Contact us to report unmaintained pools.
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 or stock with surface-feeding fish to control mosquito production.
8) Dispose of any used, rimless tires to prevent water accumulation. The District will accept up to 4 tires from residents for disposal. Please contact us for further details.
Lastly, this season has produced an extremely large tick population. Over 15 species of ticks can be found in Illinois with the most common being the American dog tick and Black Legged deer tick.
Late spring and early summer is also the time of year where nymph deer ticks, which are the primary vector of Lyme disease, can be found in their highest numbers. They are found in leaf litter and low growing plants in shady, wooded areas. Nymph ticks are extremely small (about the size of a poppy seed), which leads them to go unnoticed. The same recommended repellents used against mosquitoes will be effective at preventing tick bites, though should be applied to the lower legs.
