There are about 5 common species of cockroaches in Ontario.
Cockroaches are mainly active at night looking for food like cloth, plants, glue, and paper. They can be located anywhere in the house, but prefer warm, moist areas.
The German cockroach is the most prevalent of the species. They lay egg cases with about 38 eggs per case, and they can produce seven cases in their 125 day lifecycle.
Roaches are a health concern due to the fact that they carry food poisoning bacteria. They can be difficult to exterminate and, therefore, sometimes requires more than one treatment. The treatments consist of liquid contact pesticides, gel bait, and dust pesticides depending on the determined strategy.
With proper education and an experienced exterminator, a professional can eliminate the pest and reduce the risk of further infestations.
