St. Louis-area homes at a glance
- 816,909 owner-occupied homes in the St. Louis, MO-IL metro area
- 1973 median year built, older than most U.S. metros
- About 6,189 owner-occupied homes per exterminating & pest control services business (median across large U.S. metros: about 5,352)
Brick city homes and inner-ring suburbs with basements sit alongside newer St. Charles County subdivisions, and the region gets hot, humid summers, real freezes and frequent spring and summer hail. With fewer pest control businesses per home than most large metros, popular providers can book up in peak season, so it pays to schedule early and get more than one quote.
Older homes: Older foundations and framing often have more gaps and settling cracks, and wood-to-soil contact is common. Ask for an exclusion check as well as treatment.
Pest control notes for St. Louis
Brown recluse spiders are the pest St. Louis homeowners ask about most. University of Missouri Extension reports one study found them in about 70 percent of sampled Missouri homes, usually in undisturbed, cluttered storage, closets and basements. Reducing clutter, sealing storage boxes and sealing gaps helps more than general spraying. Eastern subterranean termites are also active statewide and typically swarm in spring, so an annual termite inspection is worth it for older homes with basements or wood near soil.
