In colder parts of the country, a hard freeze shuts most pests down for months. San Antonio rarely gets that break. Our short, mild winters mean insects and rodents stay active most of the year, and the pests you see simply change with the season. Knowing what to expect helps you spot trouble early.
Spring is the busiest season for termites. Subterranean termite colonies send out winged swarmers, usually on a warm day after rain. A swarm inside your house, or piles of discarded wings on a windowsill, is a strong sign of an active colony nearby.
Heat drives a lot of pest activity in South Texas. Insects that live outside start looking for water and shade, and many of them find it inside your home.
As nights cool off, pests start looking for shelter. Fall is when rats and mice move into attics and garages, and spiders become more noticeable as they follow the insects they eat. Crickets and other occasional invaders can show up in large numbers too.
Winter doesn't mean pest-free in San Antonio. Rodents that moved in during fall are now nesting. German roaches keep breeding indoors, since your kitchen stays warm all year. Overwintering insects hide in wall voids and attics until spring. Winter is also a good time to seal entry points before spring activity starts. Our winter pest-proofing guide has a checklist.
Treating each pest as it appears means you're always reacting to a problem that has already started. A prevention program works the other way. Scheduled visits treat the outside of your home before each season's pests arrive, and a technician checks for early warning signs each time. Most San Antonio homes do well on a quarterly plan. If you're not sure what you need, read how often you should get pest control in Texas.
