There are four main types of cockroaches, all with prolific reproductive cycles. Some prefer kitchens, bathrooms, or bedrooms whereas others prefer basements and sewers. They require food, water, warmth and shelter. Infestations are invariably larger where sanitation is poor.
Cockroaches live in clusters and rarely travel more than a few feet from their living clusters when foraging. They actively seek darkness and take advantage of cracks and crevices, only emerging to forage for food and water. This means that infestations can be difficult to control by chemicals that require direct contact, however, your pest control technician will thoroughly treat all refuges that appeal to cockroaches.
