Rodents in the Northeast may be gaining an edge over pest control efforts thanks to a genetic mutation that could be making them more resistant to typical methods used to keep them at bay.
In a new study, researchers at Rutgers University found that about 84 percent of mice tested from Northeast urban areas carried at least one genetic mutation that makes them resistant to poisons commonly used to control them.
“For years, pest control professionals throughout the Northeast have reported a troubling pattern. In some neighborhoods, rodents seemed increasingly more difficult to eliminate, even when standard control methods were used,” Rutgers said in a statement.
