How can Cockroaches Affect Us?
Cockroaches can breed very quickly, especially if there is food available for them to feed on. The eggs hatch into larvae which then grow into adults. Adults can live up to 2 years while the larvae can survive for about 4 months.
Cockroaches are known to carry many diseases including salmonella, E coli, listeria, and typhoid fever. They are often found near waste matter or in the kitchen, where there is food. They can contaminate food and spread disease through its faeces. Roaches can also cause allergic reactions in people who are sensitive to them. They can also bite or sting humans causing minor injuries such as a rash, skin irritation, or swelling.
Identifying the Problem
The first sign that you have a cockroach infestation is when you notice droppings or excrement on your floor. Other indications include egg casings and skin sheds.
Although it is believed that poor housekeeping invites these pests, this may not always be true. Roaches enter houses through cracks and crevices found in exterior of building, through drain or sewage pipes or even fly in through the window! Hence, they are not limited to just the kitchen. They feed mainly at night and are attracted by food sources, so a clean environment is still necessary.
