Using Dry Ice as a Pest Control Method

When you think of ‘pest control’, what comes to mind? An exterminator with a respiratory mask? Strategically placed poison that you can’t allow children or pets around? The hassle of fumigating and laying traps?

How about using dry ice as pest control?

While it initially may seem unlikely, dry ice has proven to be an excellent way to combat certain types of pests. It is non-toxic, environmentally-safe, and effective. 


Gophers are burrowing mammals that can wreak havoc on farms and gardens. They are considered pests because they can leave soil denuded, meaning it is not fit for planting. To combat gophers, 3-5 pounds of dry ice are placed into every hole that can be found and then the holes are filled with yesterday’s newspaper. As the dry ice sublimates, the heavy carbon dioxide vapors displace oxygen and sink to the bottom of the holes, depleting the air supply of the gophers.


Mosquitoes are attracted to carbon dioxide, which animals and people exhale. Since mosquitoes gravitate towards higher concentrations of carbon dioxide, it stands to reason that they would be attracted to dry ice due to the vapors produced by sublimation.

If you’re having an outdoor event such as a cookout or pool party, this could be an excellent option for keeping mosquitoes at bay. Place a piece of dry ice in a mosquito trap or a container that you can put in a well-ventilated location away from children and pets. Replenish as needed.


Bed bugs are a scourge that can strike fear in a homeowner. Not only are they bothersome, they can be frustrating to eradicate. Professional exterminators should be brought out in the event of bed bugs, but there are certain measures you can take while the experts treat the issue. 

You can take the items that are difficult to wash, like toys, pillows, bed covers, and so on, and put them in a plastic bag containing dry ice. Make sure you are wearing heavy gloves and preferably use tongs to handle the dry ice. The displacement of oxygen by carbon dioxide vapors will suffocate the bedbugs.


This person’s account of a successful dry ice fumigation is an excellent example of how effective this method can be: 

Jim Lockhart of Littleton Colorado encountered powder beetles in a cabinet he had purchased at an estate sale. The larvae of powder beetles drill through wood so effectively that it can be quickly reduced to mulch in very little time. Recalling what he had been told by others about using dry ice to solve the pest problem within his new purchase, he decided to try it out himself. 

“After allowing the infected cabinet to spend 18 hours in the closed freezer with 30 lbs of dry ice at -25 deg F, I went ahead and removed the dry ice, saving what was left of it in a small ice chest. I closed the freezer up again and allowed the cabinet inside to slowly warm up to room temperature (another 12 hours) then took it out. I checked for signs of life with a stethoscope in the places where the powder post beetles could be heard and – not a sound. I checked again for signs of life 24 hours later – still nothing. It would appear that the insects either froze, suffocated or both. Of course I have no way to tell whether or not the freezing or lack of oxygen also killed any eggs – only time will tell. I am confident enough at this point that this worked and would recommend it to anyone in a similar situation…..This is a much less toxic way of killing insects than the use of chemical sprays and fumigants.”
