"In indoor conditions, cockroaches may alter a body in a similar
manner as to that of fire ants in outdoor conditions. Cockroaches
are scavengers on filth and refuse, but some species will feed on
carrion when available, or even on living animals as well as the
skin of living humans. Often babies that are left unattended in
tenements and housing where unsanitary conditions prevail
have been found with wounds indicating cockroach feeding."
