The German cockroach is one of the most commonly-found species in homes worldwide. It is between 1.3 cm and 1.6 cm long and its colour is tan to light brown with two dark parallel lines going from the head all the way down to the base of the wings. Cockroaches have wings, but they cannot fly; they only use their wings to glide.
Development and Behaviours
The female lays between 8 and 48 eggs in a capsule called an ootheca which is attached to her abdomen. She then carries it around for approximately 28 days. Cockroaches live in any area where they have access to food, water, and shelter. They are attracted by large buildings because of the warm and humid conditions found in kitchens, bathrooms, basements, and plumbing installations. Their presence does not necessarily mean that a location is unclean. Cockroaches and their eggs can enter a residence on various objects such as old furniture, food items, empty beer and soft drink bottles as well as boxes used for transportation. Once inside a building, cockroaches can move around easily. Since cockroaches are more active at night, they cannot be detected for a certain period of time. Cockroaches like foods that contain starch, sugars, and proteins, but they can eat anything when they are famished. Cockroaches rarely cause damage to structures. They can, however, contaminate foods and pass on diseases after being in contact with trash or sewers by walking on and leaving droppings on food or in food preparation areas. People suffering from asthma may have undesirable reactions when in contact with excrements and/or exuviae (outer shell discarding during molting).
Preventing an infestation of German cockroaches begins with keeping the house clean in order to cut off their access to food, water, and shelter.
- Clean up messes immediately. Do not allow your pet’s water and food to be accessible all day.
- Keep food in sealed plastic or glass containers rather than in paper or cardboard containers that cockroaches can chew on and lay eggs in.
- Regularly clean dark and humid areas near food sources, such as debris under and behind appliances, and accumulated grease behind the stove and refrigerator.
- Dispose of trash in sealed plastic bags and get rid of it every day.
Seal and caulk all cracks, fissures, and openings around pipes to reduce cockroaches’ hiding places. Use sticky traps to detect cockroach populations and to know where they are hiding in order to better focus your elimination efforts. Contact us today!
