Gophers or ground squirrels are common pests in North America, that can destroy the fruits of your hard labour. They create extensive underground tunnels and are mostly active at night. A typical gopher infested yard looks like this with mounds of mud and dirt piled up at the entrances to the tunnels.
What would be a good way to get rid of the gophers in a non-lethal way? I know that there are professionals who do come out, lay traps and kill them or you could buy some rodent poison at the local Home Depot/any gardening store. I'd like to know if there are alternatives to these because a) the first option can be expensive and b) I don't want to end up with a bunch of dead animals in my yard when I have no clue how/where to dispose them.
