I had a friend Walter in San Francisco with a severe gopher problem. His entire front yard, which was on a slight upslope behind a low retaining wall, was riddled with gopher holes. He tried poison bait, flooding, gas, traps to no avail. The gophers merely laughed at him from a convenient nearby hillock.
Walter was a chemist so he decided to try "better living through----" He brought a bar of sodium home from the lab one sunny weekend. He sliced the bar into gopher-tunnel sized pieces, shoved them down random holes, and then flooded the burrows with his garden hose.
A few moments later, with a giant rumbling "phoom," his lawn blew up.
It was Saturday morning in an Italian district so all his neighbors were out working in their yards. Silence fell as pieces of Walter's real estate fell back to earth. You could hear a pin drop for at least five minutes.
It took Walter over a year to refurbish the front sod. The gophers, disgusted, moved to his back yard.
oh! please I have a new home with the side and the back facing the mountain. I don't have the landscaping yet, and is all dirt around. A few weeks ago I started to see holes all around and I tried everything. Not the traps because is very expensive. I have almost hundreds of holes. Also I tried the dish soap with the castor oil. I am afraid to start the landscaping. Tell me exactly what to do. I don't know where to find the bar of sodium. How to handle? It has another name? Please tell me how much, how frequently. Explain me step by step, I am desperate. Thank you.
