American Cockroach Facts And How To Control Them

August 18, 2021

Your house could be home to all manner of critters, including cockroaches. When it comes to cockroaches, differentiating them can be challenging, given the many different species of roaches. But there is one type of cockroach that is commonly found in most homes – the American cockroach. American roaches are the largest common cockroach species. Anyway, this should not be something to worry about at all. They are manageable regardless of their huge size.

What American Roaches Look Like

An adult American roach is around 1.5 inches long, with the biggest roach growing up to 2 inches. It is reddish-brown and features a yellow band behind its head. Like all other cockroaches, it has six legs, a pair of antennae and an oval body shape. Additionally, it has wings that enable it to fly short distances.

Reproduction

Females lay eggs with capsule-shaped protective cases and deposit them in warm, hidden areas. On average, a single egg capsule contains about sixteen eggs. After the eggs hatch, small nymphs come out of the capsule. Cockroach nymphs go through a series of moults and emerge as adults from their last moult. American cockroaches can go from hatching to adulthood in less than six months with ample food.

American cockroaches develop wings when they are adults. The wings enable them to fly away when they are threatened. They mainly inhabit outdoor spaces. You will readily find them under mulch or around flowerbeds. Some people refer to them as palmetto bugs since they like living on fan palms too. Another place they love hanging around is inside sewer systems.

Although American roaches are primarily outdoor creatures, they invade houses in search of food and water. They gain entry through garages, weather stripping and basement windows. Once they are inside, they proceed to the kitchen, basement, bathroom or laundry room. Then, they make themselves at home in appliances, drains and cabinets. Hungry, they will feed on anything they find, including crumbs, spilled food, dead insects, glue and wood.
