Spring 2026: What St. Louis Homeowners Are Dealing With
A warmer-than-average winter across the St. Louis metro has entomologists and licensed pest control operators expecting an early and aggressive spring pest season. Termite swarms are being reported as early as late February in some parts of St. Louis County, running two to three weeks ahead of the historical norm.
Meanwhile, bed bug service calls in St. Charles County and western St. Louis County have continued their upward trend, with providers citing hotel travel and secondhand furniture purchases as the primary vectors. For bed bug treatment in the St. Louis metro, see St. Louis Bed Bug Control.

Subterranean Termites — The entire St. Louis metro sits in the moderate-to-heavy pressure zone according to USDA maps. Swarm season runs March through May. Annual inspections are the most cost-effective defense, particularly for homes with crawl spaces or wood-to-soil contact.
Bed Bugs — St. Louis ranks consistently among the top 50 cities nationally for bed bug activity. Hotels along the I-44 and I-70 corridors, multifamily housing, and college dormitories see the highest incidence. Self-treatment rarely works and often worsens the infestation.
Brown Recluse Spiders — Missouri is within the core range of the brown recluse, and St. Louis area homes — particularly older housing stock with attics and unfinished basements — can harbor large populations without residents being aware. Professional treatment is required to access wall voids and insulation where populations establish.
House Mice & Norway Rats — Rodent pressure spikes in October and November as temperatures drop. Rural and semi-rural properties along the St. Louis exurban fringe face higher pressure due to agricultural adjacency. Exclusion work — sealing entry points — must accompany population reduction for lasting results.
Finding a Licensed Missouri Pest Control Provider
Missouri requires all commercial pesticide applicators to be licensed through the Missouri Department of Agriculture. Always verify the technician's individual license — not just the company's registration. For termite work, look for Category 7B (Wood Destroying Organisms) licensure specifically.
