All About German Cockroaches

German cockroaches (Blattella germanica) are a common household pest known for their rapid reproduction and ability to spread bacteria and allergens. Effective control and management are crucial to prevent health risks and infestations in homes and businesses.

What are German Cockroaches?

German cockroaches, scientifically named Blattella germanica, are small, light brown to tan insects with two dark stripes on their backs. They are notorious for infesting indoor environments and are one of the most common cockroach species found worldwide.

These cockroaches thrive in warm, humid environments and are excellent hitchhikers, often spreading through infested items like grocery bags and appliances. They prefer to run rather than fly and are omnivorous, feeding on various materials, including food scraps, glue, and soap.
