Our Mosquito Control program treats resting spots — dense shrubs, shaded fence lines, under decks — where adult mosquitoes actually spend the day between feedings. A single mosquito generation can go from egg to biting adult in about a week during warm weather, which is why standing-water inspection has to happen every visit, not just once at the start.
A technician maps every breeding source and resting spot on the property before quoting a monthly treatment plan.


Every technician treating Affton yards for mosquitoes carries state pesticide application licensing and liability coverage.
One-time treatments ahead of an outdoor event can usually be scheduled within a day or two.
One-time yard treatments are quoted flat based on lot size, with no hidden per-visit fees.
We use backpack sprayers for foliage barrier treatment and separate larvicide dunks or briquettes for standing water.
Larvicide dunks and briquettes go directly into standing water sources that can't be drained, breaking the breeding cycle at the source.
We treat the underside of leaves and dense foliage specifically, since that's where adult mosquitoes rest during the day.
A monthly schedule through peak season keeps mosquito pressure consistently low instead of spiking between one-time treatments.
ULV fogging can clear a yard fast ahead of a wedding, graduation, or backyard event on short notice.
We flag chronic water sources — clogged gutters, low spots, unused pots — that keep re-seeding the population between visits.
Yards near wooded or grassy areas often need a separate granular tick treatment along the perimeter where pets and kids play.

Tell dispatch whether you need pre-event knockdown or ongoing monthly protection, and we'll match the right service.
Our mobile units carry both barrier spray and larvicide product so no return trip is needed for mixed treatment.
We walk the property, flag every standing-water source, and quote a flat rate for one-time or monthly service.
Barrier spray and larvicide go down the same visit, with monthly plans scheduled automatically through peak season.
They found a clogged gutter section we never would have thought to check, which turned out to be the real breeding source.
One-time service was quoted flat and scheduled within two days — exactly what we needed on short notice.
We're near a wooded lot and mosquitoes plus ticks were both a problem. Bundling both treatments into one visit was convenient and cost less than doing them separately.
The technician pointed out an old tire in the side yard holding water that we'd completely forgotten about — that alone made a noticeable difference.

Nex Pest Control dispatches mosquito-specialized technicians throughout Affton and nearby communities, with barrier spray and larvicide stocked on every service vehicle. Whether it's a small backyard or a larger commercial property, treatment routes are planned to keep Affton coverage consistent all season.

We'll recommend frequency based on what your yard's water sources and foliage density actually require.
We apply barrier spray to resting foliage, not blooming plants, specifically to reduce impact on pollinators.
Most yards see a noticeable drop in adult mosquito activity within 24 to 48 hours of barrier application.
Yes, one-time treatments can usually be scheduled within a day or two and timed to peak right before your event.
We'll tell you the specific re-entry time for your treatment, which is typically once the product has dried.
Tick treatment focuses on the yard perimeter and grassy edges where pets and kids spend the most time.
