Local pest control in Weldon Spring

Your Weldon Spring exterminator, close to home

Weldon Spring (many people search for it as Weldon Springs) is surrounded by protected land: the August A. Busch Memorial and Weldon Spring conservation areas, the Katy Trail and miles of Missouri River bluffs. That natural setting is a big reason people move here, and it also means wildlife and the pests that ride along with it are never far from your back door.

Deer, rodents and dense woods bring ticks, mice and voles close to homes, while large lots with outbuildings give wasps and spiders plenty of places to settle. McCarthy creates a perimeter plan that respects the outdoors you love and keeps pests outside where they belong.

We serve homes and businesses throughout Weldon Spring (ZIP 63304) with residential pest control, commercial service and termite protection, all backed by our free re-treatment guarantee.

What we see most

Common pests in Weldon Spring homes and businesses

Ticks

Large deer populations in the nearby conservation areas carry ticks into wooded yards along Highway 94 and Weldon Spring Heights.

Mice and voles

Field and woodland rodents move into garages, sheds and basements every fall. Voles also tunnel through lawns and landscape beds.

Stinging insects

Wasps, hornets and yellowjackets nest in trees, eaves and outbuildings on larger wooded lots.

Camel crickets and spiders

Damp basements and crawlspaces in wooded areas attract camel crickets, which in turn draw spiders.
