Many cities are turning to dry ice to help eliminate rat and rodent problems.
If you live in Connecticut, you’d think that this cold winter weather would have killed the rats off in their tunnels by the time Spring comes along, but you’d be wrong. It’s not the cold in dry ice that kills the rats, it’s the carbon dioxide that suffocates them. Jim Fredericks, a senior entomologist at the National Pest Management Association says “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,”
Dry ice is made up of frozen carbon dioxide. It’s freezing point is -109 degrees Fahrenheit. When dry ice is placed into active rat or rodent holes it melts and the carbon dioxide seeps into the rat tunnels. Rat tunnels typically have only one entrance and exit hole. So, the rat is trapped inside and only has the co2 to breathe in. Thus causing it to suffocate. A disadvantage of using dry ice to kill rats and rodents is that it is so cold that if you don’t wear protective gloves when handling it you will get burnt. The main advantage is that pets and small children are not likely to eat it like the do with rat and rodent poisons.
Rats can last all winter long through sub-zero temperatures in their tunnels. They don’t hibernate like bears or chipmunks do. Although they would much rather overwinter in your nice warm home. If they can’t get in your home they will survive anyways. Rats store up extra food in their tunnels to last them through winter. Here’s a disgusting rat fact: they urinate on the food to mark it as their own so other rats and animals won’t eat it.
Using dry ice in Connecticut is a partial solution to getting rid of a rat infestation in you home or business. In order to eliminate the nasty rodents you must first take some preliminary precautions: don’t leave garbage outside where they have access to it, rats also need water, so minimize any water access also. Seal up any holes or entryways into your home or business that would allow the rats, mice, or rodents to get in. Hire a reputable Connecticut licensed rodent control expert to handle any trapping, pesticides, and removal of the rodents.

• Seal cracks and holes on the outside of the home, paying special attention to where utilities and pipes enter the home;
• Store firewood at least 20 feet away from the house and five feet off the ground; keep shrubbery and branches cut back from the house;
• Eliminate all sources of moisture, including leaky pipes and clogged drains;
• Keep food including dog and cat food in rodent-proof containers;
• In basements and attics, don’t store boxes on the floor;
• Call a pest professional early to prevent a rodent problem from getting out of hand.
