Gassing gophers Baldwin says that fumigation is an effective way to eliminate burrowing pests. Gas cartridges release carbon dioxide and car- bon monoxide, which suffocate the rodents. "They can give 70% control for ground squirrels, but gophers wall-off their burrows," he said. Gas cartridges shouldn't be used close to buildings. Baldwin said that aluminum phosphide tablets, which release toxic phosphine gas when moistened in a tunnel, are very effec- tive against pocket gophers. They also can be ingested with bait and result in "close to 100% kill," Baldwin said. There is no me- chanical probe for inserting it, however. Growers have to probe, drop in the tablet and close the hole. Aluminum phosphide is classified as a restricted-use pesti- cide. It may be purchased and used only by certified applica- tors who have to be licensed, file an intent and report to use it and post signs around the site. It can't be used within 100 feet of a building. Baldwin said that vibrating stakes and repellents advertised on TV aren't effective, either.

While acknowledging that it can be satisfying a few times, Baldwin says it really isn't very effective, and it can cause fires and damage pipes. It can also alarm neighbors. While Baldwin said that academics were not entirely sure of the actual impact gophers have on vines, he said, "If they can't find other foods, they'll chew on vines, especially younger ones."
