Dry ice effect on plants

Asked July 30, 2019, 2:49 PM EDT

We have a rat burrow uncomfortably close to our house. It is at the base of a tree. I know that DC, New York and Chicago are advocating using dry ice (shoving some --about a pound or two - down rat burrows) as a way to eradicate rats. Before doing this, I wanted to know I if the melting dry ice (which suffocates the rodents) would hurt the tree at all. Thanks!

The dry ice won't damage roots of the trees. However, we do not have research and cannot recommend using it.
Here is some information on rat control https://www.princegeorgescountymd.gov/DocumentCenter/View/9566/Facts-about-Controlling-Rats-and-Mice...=
