Your lawn and garden are your outdoor sanctuaries. Whether you’re grilling dinner, entertaining friends, or simply relaxing after a long day, your outdoor space should be a haven. 

Unfortunately, the presence of even a few gophers is enough to transform that peaceful space into a nightmare. With their unsightly holes and the damage they do to plants, gophers can quickly wreak havoc on landscaping.

Fortunately, there are ways to get rid of gophers and reclaim your property. Here at Smith’s Pest Management, our team has helped thousands of San Francisco Bay Area residents deal with their gopher problems once and for all, so we know how to get rid of these pesky rodents. 

In this post, we’ll share our top gopher control tips and help you understand which is best for you.

Let's dive in.

What are Gophers?

Gophers are small, furry rodents that grow to 5-14 inches in length and can weigh a pound or more. Like mice and voles, gophers are built to dig. They have external, fur-lined cheek pouches that extend to the shoulders and are used to store and transport food. 

Their four large incisors grow throughout the gopher’s life and are perfect for chewing through tough, woody plants. To dig as efficiently as possible, gophers can close their lips behind those incisors to keep the dirt out of their mouths while moving quickly through the ground. Their small ears and eyes and short, powerful bodies travel efficiently through tunnels while their broad feet and sharp claws work like shovels to move soil. 

Although they prefer to live in areas with loose, sandy soil, Gophers are found throughout North and Central America. When they move into an area, they create an extensive network of burrows and tunnels, where they live, breed, and store food.

How to identify Gopher Damage in Your Yard and Garden 

It’s easy to tell where gophers live. As they dig tunnels, they push excess soil to the surface, which creates long mounds that are easily visible in a lawn or garden. 

However, the presence of mounds alone isn’t enough to identify gophers since moles also make mounds. We discussed the difference between mole and gopher mounds in one of our previous articles, “How to Identify Gopher Damage in Your Yard.

Here’s the easiest way to determine whether the mounds you’re seeing are the work of gophers or moles:

When gophers make a mound, they push the dirt out so it creates a fan pattern. Moles, on the other hand, create neat, conical mounds. Additionally, gophers plug the entry holes to their tunnels. If you look closely, you’ll probably be able to see the plugs sitting on the top of a mound. 

Finally, gophers break up soil as they dig their tunnels, creating fine, sifted soil. Moles move soil in large clumps and only create a tunnel entrance every six feet or so, while gophers create a tight-knit group of tunnels and holes in close proximity to one another. 

Gophers are active during the day, and they do not hibernate, so the presence of gophers in your yard or garden will be relatively easy to spot. 

Why Do I Have Gophers in My Yard? 

Humans aren’t the only ones who love a beautiful yard! Here are a few things that may be drawing gophers to your property:

  • Food sources. Gophers need to eat, and they’ll set up shop anywhere they can find ample food sources. Gophers are herbivores, which means they only eat vegetation. They especially love the roots and tubers of plants but will occasionally resort to “grazing” the lawn for grass, clover, and other snacks. 
  • Soil composition. Because gophers love to excavate, they prefer to live in areas with loose, sandy soil that’s easy to move.
  • Shelter. Gophers are a prey animal for many other animals, so they need plenty of protection to stay safe. They may build tunnels under bushes, along fence lines, or under trees. 

Once you have a few gophers in your yard, the problem will snowball as the gophers reproduce. Female gophers have between one and three litters per year, with each litter containing five to six pups. The young stay at their mother’s side for a few weeks before going out on their own to build burrows and make tunnels. 

With that in mind, it’s smart to address gopher infestations quickly - before they become hard to manage. 

How to Deal With Gophers Humanely & Naturally

Wondering how to get rid of gophers without killing them? Fortunately, there are many options, including poison-free methods. 

Here’s a breakdown of each:

No-Kill Traps

If you’re interested in using poison-free methods in your yard and lawn, trapping is the most effective approach. While you can set out gopher traps all year long, they work best in the spring and fall since that’s when gophers are most active. 

For best results, traps should be set in main tunnels and baited with carrots, lettuce, apples, or peanut butter. If a trap doesn’t catch a gopher within 48 hours, it should be moved to a new location. 

Pros: Effective, humane

Cons: Time-consuming, require manual placement and replacement

Exclusion Fencing

Instead of trapping and removing gophers, exclusion fencing keeps them away from food sources. Since gophers like to feed on roots and tubers, installing exclusion fencing (made from fine metal mesh) can prevent pests from burrowing into vulnerable areas of your lawn or garden or pushing soil to the surface. 

You can either place exclusion fencing around areas you want to protect (like the garden), dig a trench and line it, or lay the fencing beneath your lawn’s sod to deter burrowing. To successfully exclude gophers, the wire mesh should have openings of less than ½” x 1”.

Pros: Effective, affordable, humane, long-term solution

Cons: Difficult to install, requires significant modification to existing landscaping

Repellants

There are plenty of humane, natural ways to deter gophers from entering your yard, and some of them rely on ingredients you probably already have in your pantry. Repellents make an area unappealing to gophers and force them to go somewhere else. While many of them are organic, they can also be mechanical, electronic, or chemical. 

Here are a few of the most common options:

Castor oil

Castor oil tastes terrible and has a laxative effect on gophers. Additionally, it has a strong smell, which discourages gophers from entering an area. For best results, place liquid castor oil in the area of your property you want to protect and around the entrance to gopher tunnels. 

Pros: Affordable, humane, non-invasive

Cons: Time-consuming, requires seasonal re-application

Ultrasonic repellents

Ultrasonic repellents create high-pitched sound waves and send them down into the ground. While people can’t hear these sounds, the constant noise is bothersome to gophers and will make them move somewhere else rapidly. 

Pros: Non-invasive, affordable, effective, humane, low-profile, long-term solution

Cons: Ultrasonic repellents encourage gophers to leave their burrows, which means they may move to another area of your landscaping unless you’ve taken adequate precautions

Natural deterrents

You can place all sorts of natural deterrents around your property to repel gophers. Growing plants with strong smells such as sage, daffodils, iris, thyme, and geranium will repel them, for example, as will placing fish oil, peppermint oil, coffee grounds, or tabasco sauce on the ground near gopher tunnels. 

Pros: Humane, eco-friendly, safe for kids and pets

Cons: Requires frequent re-application

Conventional Methods to Get Rid of Gophers

If you’d like to take a stronger approach to getting rid of gophers, there are more conventional methods that can make short work of colonies. Please note that Smith’s does not recommend these methods, and tries to take a humane approach whenever possible. 

Kill Traps

While some traps confine and contain live gophers, others kill them immediately. These traps are an effective way to eradicate gophers, although we do not recommend this method because it is not humane and there are other methods that are just as effective - like no- kill traps.

Pros: Effective, rapid solution

Cons: May not be appealing to some people, inhumane, and requires disposal of dead animals 

Bait

Poisonous gopher bait looks and smells like a tasty treat to gophers. When they consume the substance, though, it kills them quickly. While baits are effective, they require cautious application. 

These potions are a potential hazard to pets and kids and are even outlawed in some places. California, for example, the rodenticide strychnine is legal but must be placed underground - never at lawn-level. Learn more about rodenticide laws in California here.

Pros: Effective, fast-acting

Cons: Highly toxic, potential danger for kids, pets, and other non-pest animals, inhumane, dangerous to the environment, can be expensive

How to Get Rid of Gophers Under the House

Gophers love a beautiful yard, but they’re also happy to tunnel under the house. And since a single gopher burrow can extend 200-2,000 square feet and contain 200 yards of tunnels, even a few gophers under the home can compromise the building’s structural integrity and create dangerous sinkholes. 

If you have gophers under your home, no-kill traps are the most effective solution. However, implementing this method can be risky and requires the help of a skilled pest management company like Smith’s.

Because of the hard-to-reach location of gopher burrows under the house, holistic methods like ultrasonic deterrents and peppermint oil are typically ineffective. 

How do Professionals Get Rid of Gophers?
