Three situations account for most of our 61817 calls. First, rodents: cold winters drive mice and rats indoors, and snow cover conceals the entry points they used so homeowners often discover droppings behind kitchen appliances long after the breach.
A mouse fits through a gap about 1/4 inch, which is why our rodent exclusion work starts at the foundation line. Second, storm damage: summer thunderstorms and tornadoes can damage screens and roof openings, letting wasps and stinging insects colonize eaves.
Quick self-check: run a hand along exterior door sweeps and basement windows after a storm. Daylight or drafts mean a gap worth sealing. We handle rodent control, ant control, wasp nest removal, and tick control across Catlin.
