Can Cockroaches Bite Humans?

Yes, it is possible for cockroaches to bite humans, but it is extremely rare. A cockroach bite can last up to a week and may cause redness, irritation, swelling, or discomfort. Cockroaches are nocturnal, omnivorous insects, meaning they eat almost anything edible—and humans are not entirely excluded.
If a bite does occur, it usually happens because the cockroach is attracted to food scents on the skin, such as food residue, sweat, or saliva, and takes a small exploratory bite. However, cockroaches are not naturally aggressive and do not seek out living humans as a food source.
Bites are most likely only in cases of severe infestations, where the cockroach population has outgrown available food sources like garbage, crumbs, or exposed food. In normal conditions, roaches will always prefer these food sources over humans.
In short, cockroach bites are a warning sign—if you are waking up with cockroach bite symptoms, it often means there is a serious infestation that requires professional pest control intervention.
