The American cockroach is the largest of the house-infesting cockroaches in Toronto, Ontario.
The Habitat of American Cockroach:
American cockroaches are found in food processing areas and food storage areas, as well as other types of buildings. They are active when the temperature is 70 degrees or higher, but they can survive lower temperatures with the right conditions.
American cockroaches are often found in sewers and basements, particularly around pipes and drains.
The Threats posed by American Cockroach:
American roaches have been reported to spread at least 33 kinds of bacteria, six kinds of parasitic worms, and at least seven other kinds of human pathogens. They can pick up germs on the spines of their legs and bodies as they crawl through decaying matter or sewage and then carry these into food or onto food surfaces. Germs that cockroaches eat from decaying matter or sewage are protected while in their bodies and may remain infective for several weeks longer than if they had been exposed to cleaning agents, rinse water, or just sunlight and air. Recent medical studies have shown that cockroach allergens cause lots of allergic reactions in inner city children. American roaches were even shown to cause asthma in children. These allergens build up in deposits of droppings, secretions, cast skins, and dead bodies of roaches.
Cockroaches in general produce odorous secretions from various points in their bodies. Such secretions can affect the flavors of various foods. When cockroach populations are high, these secretions may result in a characteristic odor in the general region of the infestation. Disease-producing organisms such as bacteria, protozoa, and viruses have been found in their bodies.
We suggest a commercially registered insecticide Bait application to exterminate American Cockroaches.
Bait: It is a very palatable substance placed strategically so that the American Cockroaches may find it easily during the foraging activities. These pesticides are commercially registered with the ministry of the environment, and can only be deployed by a licensed exterminator. Once American Cockroaches ingests the deployed substance as a meal, it is considered to have had a lethal dose.
The bait is not instantly lethal to the American Cockroaches. The advantage is that the bait will reach into American Cockroaches nesting areas and will affect all American Cockroaches. American Cockroaches would likely die off in the nesting areas and not in our living spaces. Since most baits are formulated such that they do not cause any immediate discomfort to the American Cockroaches ; they are likely to have multiple feedings and encourage other members to feed as well.
