Mosquito Control in St. Louis
Entomologist-Backed Mosquito Treatment for Homes & Businesses
Mosquitoes in the St. Louis area aren’t just an inconvenience. West Nile virus is considered endemic in the City of St. Louis, and St. Louis County health officials detected West Nile virus-positive mosquitoes at sites across north and west St. Louis County as recently as 2025. St. Louis encephalitis, the arbovirus first identified during a 1933 epidemic in this city, remains an actively monitored concern in regional mosquito surveillance programs. From May through September, the region’s humid summers create sustained pressure that demands more than a generic spray schedule.
We’ve served the St. Louis Metro as a family- and veteran-owned company since 2000, bringing over 75 years of combined pest management experience to every property we treat. What separates us from mosquito-only franchise competitors is straightforward: our team includes an on-staff entomologist who grounds every treatment decision in mosquito biology, not a one-size-fits-all franchise playbook. We provide mosquito control for residential yards, commercial properties, restaurants with outdoor seating, and businesses with outdoor common areas throughout the St. Louis Metro.
Same-day and emergency service is available when mosquitoes can’t wait. Call us at (636) 306-3931 or reach out online for a free estimate.

How Our Mosquito Control Process Works
Effective mosquito spraying in St. Louis starts with a thorough property inspection. We walk the property to locate breeding sites: clogged gutters, birdbaths, containers, and low-lying areas that collect water. We also identify the shaded, dense vegetation where adult mosquitoes rest during daylight hours. That inspection shapes exactly where and when we treat.
Our on-staff entomologist’s knowledge of the mosquito lifecycle informs our treatment timing. Mosquitoes pass through egg, larval, pupal, and adult stages; scheduling treatments around that cycle helps reduce new populations from establishing before the previous generation is addressed. Barrier spray treatments go onto foliage, shrubs, under-deck areas, and other shaded zones (where mosquitoes actually rest), not broadcast into open air. We also provide standing water guidance so you can reduce breeding habitat between professional visits.
Residential & Commercial Mosquito Treatment Options
Our mosquito control service in St. Louis is available as a one-time treatment or on a recurring seasonal schedule. One-time treatments are a practical choice before outdoor weddings, parties, and backyard events when you want treatment for a specific date. Recurring service provides more consistent coverage through the full May-through-September active period. This approach fits properties with sustained pressure.
Commercial properties have distinct needs. Restaurants with outdoor seating, hospitality venues, and businesses with outdoor common areas require treatment plans that account for guest traffic, operational hours, and site layout. We tailor our approach to each property rather than applying a standard residential protocol to a commercial space.
