Central Texas winters are mild most of the time, but every cold snap sends the big outdoor roaches looking for somewhere warm. That’s why people often see more of them in December and January than they expect.
Where they’re coming from
American roaches live outside in mulch, leaf piles, drains and sewer lines. When temperatures drop, they follow warm air and moisture into garages, attics, bathrooms and kitchens. Weep holes in brick, gaps under doors and openings around plumbing are the usual ways in.
Big roach or small roach?
The big reddish-brown ones are usually outdoor roaches that wandered in, and regular exterior treatment handles them. Small tan roaches in the kitchen during the day are German roaches, a different problem that breeds indoors. If you’re seeing those, read more on our roach control page.
What helps this time of year
- Put door sweeps on garage and exterior doors
- Keep drains clear and run water in rarely used sinks and tubs
- Rake leaves and thin mulch away from the foundation
- Don’t stop your quarterly service in the winter. The winter visit keeps the barrier up when roaches are looking for a way in.
