Signs you have a cockroach infestation
Faeces - The insects produce small black pepper like droppings. Larger species excrete cylindrical faeces. You may be able to smell the strange musty odour cockroaches produce.
Eggs - Eggs and egg cases might be found behind and under furniture.
Skin fragments - These are more difficult to spot in the roaches’ dark hiding places.
Live roaches - They breed in a matter of weeks, so you may see them in their numbers if you switch on the light at night. Roaches will nibble at books and food packages. If you see live roaches, be sure to call and book a cockroach control service immediately. This signifies a serious problem.
