Mosquito Season Has Started on the North Shore

Mosquito season has arrived on Chicago's North Shore. Learn why organic mosquito treatments are an effective choice for families and pets.

5/8/20261 min read

Mosquito season in Illinois is officially underway. Once overnight temperatures hold above 50°F — which has already happened across the Chicago North Shore — mosquitoes begin hatching, feeding, and breeding fast. That means right now, in May, is the single most important window to act.

Why treat now instead of June?

The mosquitoes you eliminate in May are the ones that would have laid hundreds of eggs in June. Treating early breaks the reproduction cycle before your yard becomes a breeding ground. One bottle cap of standing water can house up to 300 mosquito eggs — your gutters, birdbaths, and flowerpots are already loaded.

Why choose Evergreen Mosquito?

Unlike conventional mosquito spraying, Evergreen Mosquito uses plant-based treatments that are safe for your kids, pets, and pollinators. Traditional pyrethroid-based mosquito sprays have been shown to kill bees, butterflies, and beneficial insects on contact — and even drift to neighboring yards. Our organic approach targets mosquitoes without the chemical fallout.

Serving Lake Forest, Highland Park, Glencoe, Wilmette, and Deerfield.
