Organic Mosquito Control in Northbrook, IL

Northbrook has one of the most significant mosquito challenges of any village on the North Shore — and the 894-acre Skokie Lagoons on the eastern border is the biggest reason. Those seven interconnected lagoons include 242 acres of water surrounded by wetland and woodland that produce mosquitoes continuously from May through September. Add the West Fork of the North Branch Chicago River running through the village, the Des Plaines River corridor to the west, and over 543 acres of parkland, and Northbrook is essentially surrounded by mosquito-breeding habitat.

Evergreen Organic Mosquito Control gives Northbrook homeowners a safe, effective, chemical-light way to protect their families all season long.​

The Skokie Lagoons Effect

The Skokie Lagoons were actually created in part for mosquito control purposes in the 1930s — but today, their shallow edges, vegetated shorelines, and protected status make them one of the largest mosquito-breeding sites in the northern suburbs. East-side Northbrook properties closest to the lagoons face the heaviest pressure from mid-May onward. Even if you live on the west side near the Des Plaines River corridor, floodwater mosquitoes from forest preserve wetlands are a consistent problem throughout the season.​

Three golf courses — including Heritage Oaks and Sportsman's Country Club — add additional maintained landscape with irrigation and standing water that contributes to seasonal mosquito populations in the surrounding neighborhoods.​

How Our Barrier Treatments Work

We apply essential oil-based sprays to the resting sites mosquitoes use during the day: under leaves, along shrub lines, in dense ground cover, under decks and outdoor furniture, and along the property perimeter. Each treatment provides approximately three weeks of protection. Our seasonal program spaces treatments throughout the summer to maintain a consistent barrier even as new mosquitoes hatch from the surrounding preserves.

We're pet-safe, kid-safe, and designed for families who want effective protection without synthetic chemicals near their home and yard.

FAQ: Does Organic Mosquito Control Really Work in Northbrook?

Yes — with realistic expectations. No treatment can eliminate every mosquito when you live adjacent to hundreds of acres of wetland preserve. What barrier treatment does is dramatically reduce the mosquitoes resting and breeding in and immediately around your property — which is where the bites happen. Clients in Northbrook near the Lagoons typically report 70–90% reduction in backyard mosquito activity after consistent seasonal treatment.
