Using dry ice to suffocate rats

Dry Ice: Newest Rat Pesticide in Major US Cities

Due to the rampant rodent infestations in New York City annually, the United States Environmental Protection Agency (USEPA) has recently permitted the state of New York to use dry ice as a rat pesticide.

Dry ice, or frozen carbon dioxide, is usually utilised in food preservation. When shoved into a rat hole, it evaporates once melted, suffocating the rodents inside their burrows.

Last month, USEPA added Rat Ice by Bell Laboratories to New York state’s official list of pesticides, Tayler Covington, a spokeswoman of the organisation, said.

According to her, dry ice can be “another tool in efforts to control these pests”.

Apart from New York, there are other large cities in the US which have put dry ice to the test in the previous year. These include Boston and Chicago.

The National Pest Management Association is hoping that Rat Ice will make rodent control easier, Jim Fredericks, a senior entomologist of the association, said.

“We’ve been in touch with multiple researchers who have been working on and with dry ice for rat control, and the results have been great”, he said.
