In Santa Cruz County, three things actually control pocket gophers: trapping, wire baskets at planting, and professional carbon monoxide treatment. Juicy Fruit gum, car exhaust, dog poop, and ultrasonic stakes do not. I learned that the hard way.
My leucodendron is dead
I had a beautiful, beautiful, beautiful leucodendron. Past tense.
A gopher killed it. The cruel irony: leucodendrons are in the Proteaceae family, plants widely considered gopher-resistant thanks to tough, fibrous roots. Most pest references say gophers leave them alone.
Mine didn’t get the memo.
May is peak gopher season here. Juveniles born in late winter are now 6 to 8 weeks old, leaving their mothers’ tunnels and claiming new territory. Yours.
What doesn’t work
Everyone has a trick. Here’s what UC’s Integrated Pest Management program and decades of research actually say.
Juicy Fruit gum
Theory: gophers eat it, can’t digest it, die. Reality: zero scientific evidence. UC researchers tested it. Gophers ignore the gum or push it out of the tunnel. The most persistent gopher myth in California, debunked for decades.
Car exhaust
Theory: tailpipe carbon monoxide suffocates the gopher. Reality: dangerous and ineffective. Gophers smell exhaust fast, plug the tunnel behind them, and retreat. Burrow systems can run 200+ feet with sealed chambers, so the gas dissipates long before it reaches the animal. Meanwhile, you’re pumping CO into your yard near your house. Mower exhaust through a garden hose is also extremely hot. Fire risk. Don’t.
Dog poop
Theory: predator scent scares them off. Reality: gophers live underground in dirt, roots, and their own waste. They are not delicate about odors. You’ve solved nothing and lost track of the dog poop.
“Gopher purge,” castor bean, garlic
Reality: UC IPM is clear. No repellent plant reliably deters gophers. Studies show gophers tunnel right past Euphorbia lathyris, castor bean, and garlic. If a gopher wants what’s on the other side, a smelly plant isn’t stopping it.
Vibrating stakes and ultrasonic devices
Reality: another clean miss. University studies find no measurable effect from vibrating stakes, ultrasonic gadgets, pinwheels, or windmills. Gophers acclimate to vibration fast. The earth shifts under them every day.
What actually works
-
Trapping. The most effective option for residential properties. Macabee and Cinch traps in active lateral tunnels are the gold standard. Finding the main tunnel takes some skill, which is why most people call a pro.
-
Exclusion. Wire gopher baskets at planting protect individual plants. For raised beds, line the bottom with hardware cloth. Doesn’t remove gophers, but keeps them off what you care about.
-
Professional carbon monoxide. The Burrow Rx machine pumps a precise CO concentration through the whole burrow system. Far more effective and safer than a tailpipe.

The takeaway
No plant is gopher-proof. Not even a leucodendron. Skip the Juicy Fruit, skip the tailpipe. Call a pro or use wire baskets at planting. I’ll be replanting, with a basket this time.
FAQ
When is gopher season in Santa Cruz County?
All year, but May and June peak. Juveniles disperse from their mothers’ tunnels at 6 to 8 weeks old.
Gopher or mole?
Gophers leave fan-shaped or crescent mounds with a soil plug on one side. Moles leave round, volcano mounds. Gophers eat roots. Moles eat insects.
Do gopher baskets work?
Yes. Wire mesh baskets at planting are the most reliable plant-by-plant protection. Roots grow through. Gophers don’t.
Should I use poison bait?
Please don’t. Bait risks pets, kids, and wildlife that eat poisoned gophers. Remember: a lot of birds eat gophers. Trapping and exclusion are safer and just as effective.
