A birdbath, clogged gutter, or unused planter can breed an entire mosquito generation in under two weeks — our technicians find and treat every standing-water source, not just spray the air. 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 Onalaska 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.
Our equipment includes ULV fogging units for rapid knockdown before an outdoor event.
Bti-based larvicide targets mosquito larvae specifically without harming beneficial insects in the same water.
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.
One-time treatments are timed to peak just before your event for maximum knockdown when it matters.
Identifying and correcting drainage issues reduces how often larvicide treatment is even needed going forward.
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.
Needed the yard treated fast before a backyard graduation party and the fogging treatment cleared it out just in time.
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.

We service residential yards, HOA common areas, and commercial outdoor spaces throughout Onalaska on the same seasonal schedule.

We'll recommend frequency based on what your yard's water sources and foliage density actually require.
Larvicide products are selective for mosquito larvae and don't affect beneficial insects sharing the same water source.
Larvicide takes slightly longer since it targets the next generation rather than adults already present.
Yes, one-time treatments can usually be scheduled within a day or two and timed to peak right before your event.
Yes, once the treated area is dry, which we'll confirm before we leave.
Tick treatment focuses on the yard perimeter and grassy edges where pets and kids spend the most time.
