How Do You Treat a Severe German Roach Infestation?

Severe German roach infestations often require attention from professional pest control companies because the cockroaches have few natural predators, breed and multiply incredibly quickly, and transmit dangerous pathogens, such as salmonella, typhus and E. Coli. Roach infestations can be treated by using various baits, insect growth regulators, dusts and roach traps. The many companies that manufacture these treatment products include Gentrol, Tekko, CimeXa, Victor Roach and Fogosol.

Treating a German roach infestation in a restaurant is slightly different because there is always a secondary food source to compete with the bait. To rid a restaurant of these pests, owners often have to spray a residual insecticide, such as Orthene PCO, or use a mop rinse insecticide that leaves an odorless, invisible residue, such as Eaton's Boric Acid Powder. Pheromone traps and aerosol bombs are popular among homeowners for their general effectiveness and ease of application.

German roaches are a small species of cockroach that usually grow to between 1/2 and 1 inch long. They have a light brown coloration and two long black strips on their protonums that extend from head to back. These roaches prefer indoor conditions and are frequently found in garbage cans, beneath sinks and inside kitchen or bathroom walls. Although they can eat almost anything, German roaches particularly enjoy feeding on the remnants of human food.
