Fossil evidence indicates that cockroaches have been on earth for over 300 million years. They are considered one of the most successful groups of animals ever known. Of the over 3500 species of cockroach around the world, only a few are common pests in Ontario structures. They go through gradual metamorphosis, meaning they go from egg to nymph to adult. The nymph molts its skin approximately 6 times, getting larger with each molt.
The German cockroach is a widely distributed urban pest. It is the most common cockroach species in houses, apartments, restaurants, hotels etc. Adult German cockroaches are 1/2 to 5/8 inches long (13 to 16mm). Nymphs are similar in appearance but simply smaller. They are usually found in kitchens and bathrooms. The German roach likes a warm and moist environment. They are scavengers and feed on a wide variety of foods. The female carries the egg capsule almost to hatch. The German roach produces a larger number of eggs per capsule when compared with other species and therefore populations increase rapidly.
Harm and Damage:
German cockroaches produce an odorous secretion and when populations are high enough this may result in a noticeable odour in the area. This odour can even affect the taste of various foods. Cockroach excrement and cast skins contain a number of allergens which may cause allergic responses such as: skin rashes, watery eyes and sneezing, congestion and asthma. Their bodies can carry disease producing organisms causing different forms of food poisoning, dysentery, diarrhea and other illnesses.
The Brown-banded cockroach is comparable in size with the German roach. The adult male is light brown and has fully developed wings. It has the ability to fly short distances. The adult female is shorter and wider with under developed wings and does not fly. Brown-banded roaches prefer warm and dry locations and therefore are found more often around refrigerators, cabinets, pantries and closets. They can be found anywhere in a dwelling as long as it’s dry and warm. A problem with the Brown-banded cockroach is that the female will detach and fasten its egg capsule in a protected and hidden area. The eggs in the capsule will not hatch out for approx. 35 to 100 days depending on the temperature. This means the infestation may appear resolved, then reappear once the eggs hatch.
Harm and Damage:
The brown-banded cockroach, similar to the German roach, is omnivorous. It can consume glue or paste, starch and certain colour dyes thereby damaging items such book bindings, wallpaper etc. They have also been known to damage non-food materials. Like the German, the Brown-banded roach can carry bacteria on their bodies and legs which can cause diseases, such as gastroenteritis and diarrhea.
Oriental, Woodland and American Cockroaches:
These larger cockroaches are not a serious problem in the Ottawa area. We do encounter them however, and have no problems eradicating them.
