With humans, efforts to eradicate illnesses sometimes result in development of drug-resistant bacteria and viruses. Scientists are finding a similar situation with NJ pest control, which appears to have some far-reaching impacts on the rat population.

Are Rat Extermination Efforts Counterproductive?

Rat infestation takes a physical, mental and economic toll on affected communities. While improvements in technology have created highly efficient rodent-killing solutions, many cities around the world are actually seeing an increase in their rat populations.

Impact of Extermination Methods on Rat Population

Once an extermination campaign ends, the results are generally temporary as rat populations quickly rebound, a phenomenon dubbed the “boomerang effect.” Rats themselves have been undergoing a couple of significant changes.

• Rats who survive extermination attempts tend to have genetic traits that make them better equipped to avoid danger. One specific gene that’s been identified actually makes rodent-killing chemicals ineffective. As these traits are passed on through reproduction, generations of “super rats” are developing.

• On the other hand, reduction in rat population causes a corresponding reduction in genetic variation, which in turn hinders their ability to respond to changing environments. Reproduction within this limited gene pool creates a type of inbreeding, leading to weak and sickly rats less likely to survive.
