    Do cockroaches bite humans?

    A:

    When no other food sources are available, due to shortages or sudden growth in a cockroach population, cockroaches may turn to attempting to feed on living human beings, according to Orkin. Cockroaches will readily consume dead humans and all other forms of carrion, but they will not try to feed on live prey unless an infestation becomes truly massive and is left totally unchecked, at which point it will be forced to seek out new sources of food.
