Austin’s warm climate means plenty of bugs thrive year-round. Homeowners often encounter a variety of insects and arthropods inside their households as well as outdoors. This guide covers some of the most common house bugs Austin residents are likely to see at some point.

Many ant species can invade Texas households. Some common ones include:

Stink Bugs

Stink bugs get their name from the foul defensive odor they release. In Austin, common types include:

  • Brown marmorated stink bugs – Marbled brown bugs that mass together during winter. Emit a harsh smell.
  • Kudzu bugs – Smaller green bugs that cluster on homes in fall. Smell like cilantro.

  • Cellar spiders – Daddy longlegs with long legs and small bodies. Eat other pests.

Occasional Invaders

Seasonal and occasional invaders include:

  • Ladybugs – enter in fall seeking warmth but don’t infest or breed inside. Vacuum up gently.
  • Carpet beetles – Feed on fabric fibers and carpeting. Cause property damage but don’t bite.
  • Crickets – Follow food sources like pet food into garages and basements. Male crickets chirp.
  • Centipedes and millipedes – Long-legged centipedes prey on other bugs. Millipedes curl up when disturbed. Neither bites humans.
