Which Cockroaches Are Pests in Human Habitats?

Cockroaches are a group of insects that belong to the family Blattodea. Of the 4,600 species, 30 are known to be pests in human habitats. However, the cockroaches that we are familiar with are not the only ones that can cause problems in human habitats.

Oriental cockroaches prefer cooler climates, which is why they usually live outdoors. These pests may also migrate into human-occupied buildings during the night, so you should keep an eye out for them. Oriental cockroaches are slow-moving and cannot climb smooth vertical surfaces, which may result in them getting trapped in drain pipes or sinks.

Adult female cockroaches lay their eggs in a protective egg case. These capsules contain between 16 and 50 eggs, depending on the species. These eggs are glued together, and the female cockroach will produce several egg cases in a year. In the US, the average lifespan of a cockroach is between 20 and 30 weeks.

Three-lined cockroaches are the most common indoor species in California and other parts of the world. These bugs are attracted to light at night. They are also known to invade structures, especially kitchens. The invasive smokybrown cockroach is a pest in southern California, but it is rare now.
