This pest is not a true social insect like bees, ants and termites that live in structured colonies. However, they tend to congregate, attracted by one another’s pheromones, in the cracks and crevices near to an available food and moisture source. German roaches are usually unwittingly brought into the home or office in grocery or market bags and boxes or very commonly in drinks cases.
The first step to controlling a German roach infestation is to clean as thoroughly and regularly as possible, eliminating all food residues. The use of a biological cleaner that neutralizes organic odors will destroy their scent and disrupt their behavior. Next identify the cracks and crevices in which they are harboring and use a product like boric powder or diatomaceous earth in and around these areas, these work best the dryer the area. Bait stations is also a good control device but they must be renewed as recommended on the label and the use of aerosol insecticides will render them ineffective.
