Pest Profile: Cockroaches

Cockroaches Biology and Life Cycle

Cockroaches move through three life stages, going from egg to nymph, and then to adult. Female cockroaches produce egg cases that contain multiple eggs, and some can produce dozens of these cases in a lifetime. Once they reach adulthood, cockroaches can live for several months, or even over a year in some cases. They tend to live longer when food and moisture are readily available. And, since they reproduce so rapidly, infestations can grow quickly and get out of control.

Cockroaches Habitat and Behaviour

Warm, dark, and moist environments are favoured by cockroaches. This is why they are often found in places like kitchens, bathrooms, and basements. They like to hide inside of walls, behind appliances, and around plumbing fixtures, among other spots. 

Cockroach behaviour is marked by their nocturnal activity. They are hidden throughout the day and become active at night to search for food and water. They are scavenger pests and will consume just about anything they can find. Seeing cockroaches during the day is a warning sign that a large infestation may be in place, as they are being forced out of hiding during daylight hours.

Cockroaches Treatment Options

The first step toward getting rid of cockroaches is reducing the food and water sources that are available. That means doing things like taking out the trash frequently, fixing leaks or cracks, and storing your food in sealed containers. Of course, if a cockroach infestation is already in place, having professional treatment performed using baiting systems or targeted insecticide applications will be the best approach.

Cockroaches FAQs

Q: Are cockroaches dangerous to humans?
A: Cockroaches can carry bacteria and contaminate food and surfaces. They are also known to trigger asthma and allergic reactions, particularly in children and sensitive individuals.

Q: Why do cockroaches keep coming back?
A: Recurring infestations can occur when untreated hiding areas are available to cockroaches, especially if food or moisture are present. Complete control of the cockroach population usually requires a professional treatment plan.

Q: Can I get rid of cockroaches on my own?
A: You might be able to improve minor problems with cockroaches by using store-bought products and upgrading sanitation. However, established infestations are extremely difficult to manage without professional treatment.
