Apartment buildings are notorious for German roaches. With shared walls, pipes, and air ducts, you rely on your neighbors to keep a German roach free environment. When an infestation is severe, German roaches may be forced to hide in less than ideal locations. They can easily access your clean apartment via all of the shared avenues of the apartment building. At the first sign of German roaches in your clean apartment, contact the manager of your apartment complex and inquire about a pest control inspection of all units. While in many cases you cannot control your neighbors, you can initiate a treatment plan for the roaches in your apartment and continually monitor to catch any new infestations early.
