Identify

Common Mosquitoes in St. Louis

The St. Louis region is home to several mosquito species capable of transmitting serious diseases. Knowing what you’re dealing with is the first step toward effective control.

Asian Tiger Mosquito

DISEASE VECTOR

Asian Tiger Mosquito

Black with distinctive white stripes on body and legs. Aggressive daytime biter. Can transmit dengue and chikungunya. Zika transmission is extremely rare in Missouri. Breeds in tiny amounts of standing water — bottle caps, plant saucers, clogged gutters.

Northern House Mosquito

DISEASE VECTOR

Northern House Mosquito

Light brown, active at dawn and dusk. Primary vector for West Nile virus in Missouri. Breeds in stagnant water — storm drains, birdbaths, abandoned pools, rain barrels.

Warning Signs

Signs You Have a Mosquito Problem

Mosquitoes aren’t just a nuisance — they’re a public health concern. If you’re noticing any of these signs, it’s time for professional intervention.

Mosquitoes Swarming at Dusk

Large numbers of mosquitoes congregating in your yard as the sun goes down is a clear indicator of a breeding population nearby.

Standing Water on Property

Any standing water — birdbaths, clogged gutters, old tires, plant saucers, forgotten buckets — is a potential mosquito breeding ground.

Buzzing Around Doors & Windows

Mosquitoes gathering near entry points are trying to get inside. This suggests high populations in your immediate landscape.

Bites After Being Outdoors

Frequent mosquito bites from spending time in your own yard means the population has reached a level that requires treatment.

Larvae in Standing Water

Tiny wriggling worms visible in standing water are mosquito larvae. Each water source can produce hundreds of adult mosquitoes.

⚠ West Nile Virus in Missouri

Missouri reports West Nile virus cases every year. While most infections cause no symptoms, serious cases can cause neurological illness. Professional mosquito control is the most effective way to reduce your exposure risk. Our barrier treatments target adult mosquitoes where they rest during the day.

Our Process

Professional Mosquito Treatment — 4 Steps

Our proven mosquito control program targets every stage of the mosquito lifecycle.

  1. Property Assessment — We identify breeding sites, resting areas, and environmental conditions that support mosquito populations on your property.
  2. Breeding Site Elimination — We address standing water sources and recommend changes to reduce or eliminate mosquito breeding habitat.
  3. Barrier Treatment — Residual application to vegetation, fences, and shaded areas where mosquitoes rest during the day. This kills mosquitoes on contact and continues working for weeks.
  4. Monthly Maintenance — Re-application throughout mosquito season (May through October) to maintain continuous protection all season long.

Prevention

Reduce Mosquitoes — Homeowner Tips

Eliminate Standing Water

Empty or treat gutters, birdbaths, plant saucers, old tires, and any container that collects water. Mosquitoes can breed in as little as a bottle cap of water.

Change Birdbath Water Weekly

If you keep a birdbath, flush and refill it at least once a week to prevent larvae from completing their development cycle.

Keep Pools Chlorinated

Maintain proper chlorine levels in swimming pools. Abandoned or neglected pools are major mosquito breeding sites.

Repair Window Screens

Fix any holes or tears in window and door screens to keep mosquitoes from entering your home.

Use Fans on Porches

Mosquitoes are weak fliers. A simple outdoor fan on your porch or patio can significantly reduce mosquito landings.

Trim Overgrown Vegetation

Mosquitoes rest in dense, shaded vegetation during the day. Keeping landscaping trimmed reduces harborage areas.

Questions

Frequently Asked Questions

How often do you treat for mosquitoes?
We treat monthly from May through October — the active mosquito season in the St. Louis area. Each treatment provides approximately 3–4 weeks of protection, and monthly visits ensure continuous coverage throughout the season.
Is it safe for pets, kids, and pollinators?
Yes. We use targeted application methods to minimize impact on pollinators. Treatments are applied to areas where mosquitoes rest — not where bees forage — and we schedule applications when bees are less active. Treated areas are safe for pets and children once dry, typically within 30–60 minutes.
Does it work for the whole yard?
Yes. Our barrier treatment covers the entire property — vegetation, fence lines, tree canopy edges, under decks, and all shaded resting areas. The goal is to eliminate mosquitoes where they hide during the day so they never reach you.
What about the neighbor’s yard?
Our barrier treatment protects your property regardless of neighboring conditions. The residual product kills mosquitoes that fly onto your treated property. While we can’t control what happens next door, our program creates a protective zone around your yard.
