Carbon Monoxide For Killing Underground Rodents

CO opher Control

T

I was asked about the carbon monoxide smoke machines for killing rodents recently and I decided to try one out. Found this link from U.C. Davis. It didn't fair too well for these expensive exhaust smoke machines, but I wanted to give it a try myself. They do have a high operating cost, and not a very high success rate. The smoke oil costs about $1 dollar per hole. The thing that bothered me the most was that the rodent hole was still there when the rodent dude was dead. The other rodents will run in from the neighborhood and take back over the tunnel. : (
