Mosquito Season Update - August 8th, 2025
The predominant mosquito this summer and source of most nuisance reports is the invasive Asian Tiger Mosquito (Aedes albopictus). These are small, dark black mosquitoes with bright white stripes. Unlike many mosquitoes, these are extra aggressive towards humans, and active during the day, with conventional control methods not being as effective against them.
They will breed in small amounts of standing water. From a plastic bag under a bush to buckets, tires, clogged gutters, trash cans, fast food cups, birdbaths, folds in a tarp, kiddy pools. Anything capable of holding water will attract and produce these mosquitoes (even if they are not currently holding water, as eggs will be laid and hatch once water fills it up). Improperly covered rain barrels, for example, have been seen to put out hundreds of them a day. Mosquitoes that carry West Nile Virus will also breed in these sources of standing water.
The Asian Tiger Mosquito has a very short flight range. Seeing numerous of these means that standing water is nearby.
In almost every service request case, neglected containers with stagnant, standing water and these mosquitoes have been found and treated, dumped, or eliminated.
We do not have the ability to go into every yard to deal with all the common sources of standing water found in population dense areas. Please check yards and alleys for standing water. Dump or throw anything out if possible. Anything too large to deal with, report to us for treatment. Any efforts can help you and your community!
Although local transmission has not been observed, these invasive mosquitoes can transmit various diseases previously not possible in the area, such as Zika, Yellow Fever, Dengue, Chikungunya. The common viruses in the Chicago area, such as West Nile Virus, are unlikely to be transmitted by them.
Dead Bird Sightings - 6/16/2025
Due to a 2025 outbreak of Avian Influenza and an elevated number of dead bird sightings, dead birds are not currently being accepted for West Nile Virus testing by any local or state Health Departments.
Instructions for proper handling and disposal for dead birds, along with other frequently asked questions can be found at the Illinois Department of Public Health's website here.
