Once there is a cockroach infestation, it can be very hard to get rid of them. Therefore, cockroaches multiply very quickly and they also adapt quickly too. There are over 4,000 different varieties of cockroaches but only about thirty of them can comfortably live with humans. This number can be further reduced to include only four varieties; the main species that cause problems in homes and businesses in Ontario.
The four main species are the German, American, Asian, and Oriental cockroaches. These vary in size from about 1/2" (German), up to 2" (American). In Ontario, the species that is most common in homes would most likely be the German variety.
Cockroaches increase in population at a very rapid rate. The German cockroach female lives about 200 days. Each egg case that she lays includes thirty to fifty eggs. In her lifetime, she will produce between four to six egg cases. German cockroaches are clearly able to thrive.
Once cockroaches infest a home, they are rarely seen. Cockroaches are nocturnal and can live up to a month with little or no food. They can also survive by eating book bindings, furniture, glue, soap, dead insects, shoe linings, and more.
