HARD TO KILL

There is a frustrating trend: infestations that once responded quickly now require more visits, more product and more creative treatment strategies. The problem is not technique. Across the country, German cockroaches and bed bugs are developing resistance to products that were once highly effective. 

THE RESISTANCE CHALLENGE. Insects develop resistance in two main ways. First, natural genetic mutations may allow some insects to survive exposure to a specific active ingredient and pass that trait to future generations, gradually reducing the product’s effectiveness. Second, repeated exposure to sublethal doses can increase production of detoxification enzymes that break down insecticides before they work. These defenses can persist and intensify across generations. Resistance is emerging nationwide.

THE TECHNICIAN’S ROLE. Effective monitoring begins with people in the field, and technicians are the industry’s early warning system. They are often the first to recognize resistance when bait stops working, populations rebound unexpectedly or standard treatments lose effectiveness. 

A SMARTER, STRONGER FUTURE. Resistance will persist, but coordinated monitoring can help stay ahead of it. In an industry built on reliability and trust, informed decisions are essential. The U.S. pest management industry has always adapted to change; now it has an opportunity to lead again.
