Cockroaches are mostly tropical insects. Those that are found in the colder climates, such as Winnipeg, are those that enter buildings. In buildings, cockroaches can become a serious pest. Fortunately, cockroaches are not known to carry a specific disease. However, they do feed on all sorts of things including human food, fabric and book bindings.
Cockroaches are black or brown in colour.
They have antennae that are longer than their body. Their stout hind legs have spines. They look like crickets and grasshoppers. When disturbed, cockroaches will run instead of hop. Young cockroaches are a few millimeters in length and look like fully grown cockroaches but without wings.
