Organic Mosquito Control in Highland Park, IL

Highland Park's natural beauty — the wooded ravines, the lakefront, the mature tree canopy — is exactly what makes its mosquito problem so persistent. Those deep, wooded ravines trap moisture, collect standing water after every rain, and provide dense shade that prevents pools from evaporating. Mosquitoes breed in the ravine bottoms and drift up into residential yards all evening. The Chicago Botanic Garden's 400 acres of lakes and wetlands just to the south, Ravinia Festival's 36 wooded acres, and the Skokie Valley Trail corridor all add to a mosquito environment that runs from May through October.

Evergreen Organic Mosquito Control protects Highland Park families with essential oil-based treatments that are safe for kids, pets, and the North Shore's sensitive ecosystems.​

West Nile Virus Is a Real Concern in Highland Park

Highland Park has been ground zero for West Nile virus activity in Lake County in recent years. In June 2025, the first West Nile positive mosquito batch in Lake County was found in a Southlake Mosquito Abatement District trap in Highland Park. The Southlake Mosquito Abatement District (SLMAD) provides community-wide larviciding and surveillance — but your backyard barrier is your responsibility. Our organic treatments give you control over your own property without waiting for municipal spray schedules.

Ravine-Adjacent Properties Need Extra Attention

If your home backs up to or is near one of Highland Park's many ravines, you're dealing with a continuous source of new mosquitoes throughout the season. Floodwater mosquitoes (Aedes vexans) hatch in large numbers after rains and immediately begin looking for resting sites — which means your yard, your deck, and your outdoor spaces. Regular seasonal treatments maintain a barrier that keeps newly hatched mosquitoes from establishing themselves on your property.​

Our Organic Treatments

We use essential oil-based, low-impact barrier sprays — no synthetic pyrethroids, no organophosphates. Treatments target shaded resting areas, shrub beds, ground cover, under decks, fence lines, and property borders. Safe for children, dogs, cats, and the lakefront ecosystem. We also offer In2Care® mosquito stations as a complementary biological control option.
