Study Finds 70% of Mice ‘Mutating’ to Survive Poison
Rutgers researchers found 84% of house mice and 35% of Norway rats carried mutations linked to resistance to common rodenticides.
- A study published in Pest Management Science this April found that urban house mice in the Northeast are genetically evolving resistance to common anticoagulant rodenticides, according to Rutgers University researchers.
- Repeated exposure to poisons over many years caused mice to develop mutations in the Vkorc1 gene, which entomologist Changlu Wang explained allows them to survive treatments more effectively.
- Researchers analyzing 147 house mice and 143 Norway rats found 84 percent of mice carried at least one Vkorc1 mutation, while roughly 70 percent showed mutations linked to resistance.
- With rodent populations appearing increasingly 'stubborn,' experts now advise agencies to rotate between different poison classes and incorporate non-chemical methods to maintain control effectiveness.
- Wang warned that resistance requires higher chemical doses, causing greater environmental impact to non-target wildlife and pets, making pest management in U.S. cities increasingly complex.
