Can Roaches Bite?

Some roaches do bite. During heavy infestations of German cockroaches, people have not only reported being bitten, but also finding roaches eating food residue around the mouths of those who are sleeping.

The German cockroach, one of the smaller roach species, is also the most common one infesting apartments, houses, hotels and restaurants in the United States. Though they do not frequently bite, these roaches often contaminate the food and utensils they walk across with the pathogenic organisms they carry on their legs and bodies. Additionally, their waste products and defensive secretions can cause severe allergic reactions in humans, such as skin rashes, sneezing and watery eyes, nasal congestion and asthma.
