After treatment some areas can be sealed or caulked Introduction All roaches need food and a source of water. Infestations are most likely in kitchens, teachers lounges, food storage areas and bathrooms. Once established, roaches use plumbing and electrical wires to move to other areas. German roaches will be the most common problem in Wisconsin. Continuing re-infestations may be associated with food vendors or in some cases roaches are carried in by students.
Roaches can mechanically carry bacteria and are a leading cause of allergy problems.
Place traps under refrigerators, dishwashers, and sinks. Traps should be monitored on a regular basis by staff or pest control people. Treatment is needed only when a problem is discovered. All roach sightings need to be communicated to the IPM coordinator so proper treatment can be started before populations build. Sanitation is important especially with the use of baits, but will not eliminate existing problems alone.
