Cockroaches are treated in many places by pest control professionals. Different species have different habitats and different preferred areas and based on these differences the pest control professional may choose to use a dust, bait, spray or other method. There are various ways to effectively deliver the chosen pesticide to the insect, and it is important that the operator chooses the best methods. Typically, roaches prefer cracks and crevices where they feel safe and secure from predators that might want to eat them.
