American Cockroach

American CockroachDescription: Large, Red-brown in colour which have a yellow border around the head.

The American cockroach is one of the largest cockroaches you will find measuring at 3.8 cm and live around houses or utilities. These pests prefer moist areas but can survive in dry climates as long as they have a readily available amount of water. American cockroaches diet consists of leaves, fungi, crumbs, algae, pet food and wood particles. Adults can live around 6 to 12 months producing up to 50 egg cases with around 16 eggs in each case per female.

But it takes 6 to 12 months for a nymph to become an adult to start breeding. Prefers to live inside. Their droppings are quite small and are normally found in hiding spots which is normally mistaken for mouse droppings to the general person. To distinguish the difference between the droppings you will notice that the American cockroach has bumps on the sides and rounded on the ends whereas the mouse droppings have hair inside, are smooth and have pointy ends. If you can smell a musty odour that doesn’t go away that is a good indication that you may have a cockroach infestation.
