The answer to 'signs of cockroach' is that common signs of cockroach infestations include seeing live cockroaches, finding cockroach droppings, spotting egg cases, and noticing a musty odor. Cockroaches can contaminate food, spread bacteria, and trigger allergies and asthma, so it's important to address an infestation quickly.
Homeowners may notice cockroaches scurrying across floors or countertops, especially at night. Cockroach droppings look like dark spots or smears, and egg cases are brown capsules that can be found in cracks and crevices. A musty, oily odor is another telltale sign of a cockroach problem.
