Missouri pest control: common pests, seasons & local options
Beneath the Gateway Arch and across the Ozarks, Missouri blends river humidity with four full seasons — a combination pests love. Kansas City, St. Louis, Springfield, and Columbia homeowners face heavy termite pressure, native brown recluse spiders, spring ants, and muggy mosquito seasons.

The four pest problems Missouri homeowners ask about most — and what drives them locally.
Termites

Missouri is the heart of brown recluse country; these native spiders are found in homes and outbuildings statewide.

Mosquitoes
Humid summers along the Missouri and Mississippi rivers breed intense mosquito seasons.
