Smoky Brown Cockroach

The Smoky Brown Cockroach

The Smoky Brown Cockroach is common in Austin and Central Texas.

The Smoky Brown Cockroach is native to the temperate regions of Asia, but they are also found in the southeastern United States, including Central Texas. Like many pests, it was probably spread through overseas shipping.

We find this to be a very common cockroach found in Austin homes.

Smoky-brown cockroaches require high humidity for survival. They are found outside in wooded areas that provide shade and moisture.They feed primarily at dusk and dawn.

They can also be seen in protected areas around homes (tree holes and mulch) and in buildings and attics. Stacks of lumber and firewood, sewer-access openings and trash piles can contribute to infestations. Once in structures they are commonly found in attics or near fireplaces.
