Brown Cockroach

A glossy reddish-brown cockroach often confused with the American cockroach. It is slightly smaller with a more uniform color.

💡

Did You Know?

It glues its egg cases to surfaces rather than dropping them, unlike the American cockroach.

Asian Cockroach

Nearly identical in appearance to the German cockroach but with very different behavior, as it lives outdoors and is strongly attracted to lights. It is an excellent flier.

💡

Did You Know?

The Asian cockroach is so similar to the German cockroach that even experts sometimes need laboratory analysis to distinguish the two species.
