Cockroaches in Toronto

While there are many types of cockroaches around the world, in Toronto and the GTA we mainly see the following five cockroaches: German, Oriental, American, Brown-banded, and Wood roach. The German cockroach is the most common of the five and is a very prolific breeder. While some people believe cockroaches are the result of unsanitary conditions, we regularly see cockroach infestations in the cleanest kitchens. They are very hard to prevent as they can be brought into a home in boxes or groceries bags. They seem to be able to find food in the most minute crack or crevice. Occasionally people bring cockroaches home from vacations in the southern U.S. or the Caribbean.

They are most commonly found around the ground-floor of buildings, although sometimes can be discovered on higher levels. They are known to love water therefore can be located in sewers, drains, basements, cellars, under sinks, baths or washing machines.

German Cockroaches

Adult German cockroaches are recognized by their light brown to tan colouring with two dark, almost parallel stripes, located on their backs. Their nymphs are dark brown to black in colour with the same dark stripes located on their backs.

German cockroaches are relatively small, they are approximately 1.5 cm in length. The female reproduces rapidly, having up to 7 sets of offspring during her lifetime and producing as many as 40 eggs at a time. While German cockroaches have wings, they rarely fly. Instead, they prefer to run.
