Pest Control in West Des Moines, IA
Connect With a Local Pro Who Knows Polk & Dallas County
West Des Moines covers more ground than people expect, and the two ends of it have almost nothing in common. Valley Junction is an 1890s railroad village of brick storefronts and old frame houses with limestone basements. Twelve minutes west, the newest streets back straight onto working corn and soybean. The Raccoon River, Walnut Creek and Jordan Creek run between them. PestAlly is a free service connecting West Des Moines homeowners with independent, licensed local pest control pros already working Polk and Dallas County.

Why West Des Moines Homes Get Hit Harder Than Most
Iowa houses are built over full basements, and that single fact shapes most of the pest work here. Footings go below a deep frost line, so nearly every home has a proper basement with a sump pit, floor drain and egress window wells — cool, damp, dark space that suits camel crickets, centipedes, cellar spiders and overwintering insects, and that gives mice a route into the floor system through the rim joist. In Valley Junction the basements are older still, with limestone or rubble foundations and original clay sewer laterals that crack with age.
The western edge is a different problem entirely. New subdivisions there sit directly against active row crop, and the farm calendar drives the pest calendar. When corn and beans come out in September and October, the field mice living in them lose cover and food on the same day and move to the nearest heated building within a week. Soybean fields also produce enormous numbers of Asian lady beetles, which leave the drying crop and mass on warm, light-coloured south walls on the first mild afternoons of October.

Seasonal Activity
What’s Active in West Des Moines, and When
Spring · Mar–May
Snowmelt fills sump pits and window wells, ants become active in slab and walk joints, and vole runways show in the thawed lawn.
Summer · Jun–Aug
Culex mosquitoes along the Raccoon River and the creeks, Japanese beetles on turf and gardens, and wasps under eaves and decks.
Fall · Sep–Nov
The heaviest window of the year — harvest pushes field mice indoors, and lady beetles, boxelder bugs, stink bugs and cluster flies hit south walls.
Winter · Dec–Feb
Mice settled in rim joists and wall voids, overwintering insects emerging on warm days, and carpenter ants quiet in damp framing.

Services
The Pest Problems West Des Moines Calls About Most
Rodent Control
Harvest is the trigger here — cutting the fields removes cover and food at once, and mice reach the nearest rim joist within days.
General Pest Control
The Iowa autumn four: Asian lady beetles off the soybean, boxelder bugs, brown marmorated stink bugs and cluster flies on south walls.
Ant Control
Carpenter ants are Iowa’s main wood-destroying insect, and the metro’s dead and declining ash trees give them ideal nesting sites near houses.
Mosquito Control
The Raccoon River bottoms and creek corridors hold water for days, breeding the Culex that carry West Nile in Iowa.
Spider Control
Egress window wells and basement corners collect cellar and wolf spiders year-round, and heated basements keep them going all winter.
Bed Bug Treatment
The Jordan Creek apartment and hotel corridor keeps them circulating, and in shared-wall buildings the neighbours have to be inspected too.
