For years, the German roach was by far the number one pest in residential and commercial kitchens. That changed with the introduction of effective roach baits, which resulted in one of the great success stories in insecticide development. German roaches became almost a second-tier pest, and remained so for over 20 years. But have you noticed? They’re back! The German cockroach is once again well established in Philadelphia. The pest control technicians at Evans Pest Control have studied the critical aspects of German cockroach biology and behavior habits that can make it one of our more challenging pests.
Here is why German Cockroaches are difficult to control.
- German roaches have an incredible rate of reproduction.
- German roaches love heat and humidity.
- German roaches spend most of their lives hidden and protected.
- German roaches aggregate (they crow together).
- German roaches protect their egg cases.
- German roach egg capsules are not susceptible to insecticides.
- German roaches regularly disperse to new areas.
- German roaches detect and avoid many insecticides.
- German roaches can develop resistance to insecticides.
- German roaches can change their normal behavior.
- German cockroaches can breed at a rate of up to six generations per year, so a pest control company may recommend a recurring treatment to address this rapid reproductive rate.
