Dry ice in the hole will cut the oxygen supply. A friend has a dry ice company,he's used it on groundhogs effectively. I’ve found that 22 shells work well on groundhogs too. I average about seven a year in my back yard. I don’t even have to throw them in the woods as the Coyotes and other creatures stop by nightly for a free meal. Bird shot in the 12 gauge is effective on snakes too if they come out. We ran a garden hose and hot water in it today. Water started to seep up from the patio 3 feet below the hole but no snakes came out.
