Will using dry ice in rat burrows hurt my Arizona blue?

Asked April 21, 2018, 7:57 AM EDT

I have many rat holes at fencing & trees on north side of my property. Rats feed at neighboring apartment dumpster and on black walnuts from huge tree on pubic land near me. Will dry ice damage roots of trees?

The dry ice won't damage roots of the trees, but we don't recommend using it an option for rat control -- it's not effective. Traps and baits are more effective.
