Underground Exterminator uses pressurized fumes to fill the burrow and go to the ground squirrel . The rodent control machine was ineffective against California ground squirrels (efficacy = 15%). Burrow size can run from 15 feet to over 200 feet in total tunnel length. We do not work with any pests besides gophers, ground squirrels, voles and rock chucks.
