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 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 has been 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

  1. Trapping. The most effective option for residential properties. Macabee and Cinch traps in active lateral tunnels are the standard tools. Finding the main tunnel takes some skill, which is why many people call a pro.
  2. Exclusion. Wire gopher baskets at planting protect individual plants. For raised beds, line the bottom with hardware cloth. This doesn’t remove gophers, but it keeps them off what you care about.
  3. Professional carbon monoxide. Purpose-built machines can pump controlled CO through the burrow system. This is different from using a vehicle or mower exhaust.

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 can be active. 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-shaped 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?

I don’t recommend it. Bait can risk pets, kids, and wildlife that eat poisoned gophers. Trapping and exclusion are safer and effective.
