do roaches smell bad
Another common sign is the presence of cockroach specks. These dark-colored specks are fecal pellets and regurgitated food, and look like grains of ground pepper. Finally, thereâs the smell. Cockroaches give off a strong, very oily odor, which becomes extremely pungent when large numbers of the insects are present. Aside from all the hygiene issues associated with a cockroach infestation, the smell itself is unpleasant and can permeate food that is left exposed to the air.
