How To Keep Gophers Out Of My Garden: Natural Solutions & Proven Methods

by

Are gophers digging up your garden and causing you headaches? How to stop gophers from destroying your plants is a common concern for gardeners everywhere. Thankfully, there are many effective ways to keep these burrowing animals out of your garden, ranging from natural gopher repellent options to more direct gopher removal methods. This guide will delve into a comprehensive approach to garden pest control, focusing on preventing gopher damage and implementing safe gopher solutions.

Fathoming the Gopher Problem

Gophers, also known as pocket gophers, are notorious for the extensive tunnel systems they create just beneath the surface of the soil. These tunnels are their primary mode of transportation and foraging, and unfortunately for gardeners, this means they often encounter and consume plant roots, bulbs, and tubers. The visible signs of their presence are usually mounds of freshly dug soil, often crescent-shaped, scattered across your lawn or garden beds. These mounds are the byproduct of their tunneling activity.

Why Gophers Love Your Garden

Your garden, with its rich, loose soil and abundant food sources, is a veritable smorgasbord for gophers. They are attracted to:

  • Tender Roots: Carrots, potatoes, beets, and other root vegetables are a prime target.
  • Bulbs: Tulips, daffodils, and gladiolus bulbs are highly desirable.
  • Succulent Stems and Shoots: Young plants and the base of established ones can be gnawed.
  • Moist Soil: Well-watered gardens provide a more comfortable environment for their tunneling.

Identifying Gopher Activity

Distinguishing gopher mounds from those of other burrowing animals like voles or moles is key to effective garden pest control.

  • Gopher Mounds: Typically fan-shaped or crescent-shaped, with a plugged entrance hole off to one side of the mound. The soil is pushed out, forming a raised pile.
  • Mole Mounds: Usually more conical or volcano-shaped, with a raised tunnel running through them. Moles are insectivores and primarily eat grubs and earthworms, so they don’t damage plants directly by eating roots, but their tunneling can still disturb plants.
  • Vole Tunnels: Often smaller and more numerous, creating surface runways through grass and ground cover, not typically large mounds of excavated soil.

Natural Gopher Repellent Strategies

Many gardeners prefer natural solutions that avoid harsh chemicals. These methods focus on making your garden less appealing to gophers or creating barriers they won’t cross.

Scent-Based Deterrents

Gophers have a keen sense of smell, and certain strong scents can be unpleasant for them.

1. Castor Oil:

This is a popular natural gopher repellent. Castor oil, when ingested or absorbed by the gopher, acts as a laxative and irritant.

  • How to Use: Mix castor oil with water and a little biodegradable liquid soap (to help emulsify the oil). Apply this mixture to affected areas and around plants you want to protect. You can also soak rags or cotton balls in castor oil and place them in active gopher holes. Reapply after rain or irrigation.
  • Pros: Non-toxic, readily available.
  • Cons: Needs frequent reapplication, effectiveness can vary.

2. Peppermint Oil:

The strong scent of peppermint is often cited as a gopher deterrent.

  • How to Use: Similar to castor oil, mix peppermint essential oil with water and a little soap. Spray it around plants and into burrows. You can also saturate cotton balls with the oil and place them in holes.
  • Pros: Pleasant smell for humans, natural.
  • Cons: Requires frequent reapplication, may not be potent enough for persistent gophers.

3. Other Strong Scents:

  • Garlic and Onion: The pungent odor of garlic and onions can deter gophers. Burying chopped garlic or onion pieces near plant roots or placing garlic spray around the perimeter of your garden can help.
  • Cayenne Pepper: Some gardeners find that sprinkling cayenne pepper around plants or into burrows deters gophers.
  • Mothballs (Use with Caution): While sometimes suggested, mothballs contain naphthalene, which is toxic and can be harmful to pets and children. Their use is often discouraged due to environmental concerns and potential health risks. Natural alternatives are generally preferred.

Plant-Based Deterrents

Certain plants are believed to deter gophers due to their scent or taste.

  • Gopher Plant (Euphorbia lathyris): This plant is traditionally believed to repel gophers. It has a milky sap that is said to be toxic to them.
  • Other Repellent Plants: Consider planting marigolds, castor bean plants (note: castor bean plants are toxic and should be handled with care, especially around children and pets), lavender, and rosemary. While their effectiveness is anecdotal, interplanting them in your garden might offer some passive protection.

Auditory and Vibrational Deterrents

Gophers rely on vibrations and sounds to navigate their underground world. Disrupting this can make your garden unappealing.

  • Wind Chimes and Spinners: Placing wind chimes, pinwheels, or other spinning garden ornaments near your garden beds can create vibrations in the soil as they move in the wind.
  • Homemade Vibrating Devices: Some gardeners use empty bottles, cans, or even old radios placed in gopher tunnels to create noise and vibrations. The theory is that the unpredictable sounds and vibrations will make the gophers uneasy and encourage them to move elsewhere.

Proven Methods for Gopher Proofing Your Garden

While natural repellents can offer some relief, for more significant gopher problems, physical barriers and more direct methods are often necessary. These are some of the most effective ways to prevent gopher damage.

Gopher Proof Fencing and Barriers

Creating physical barriers is one of the most reliable ways to keep gophers out of specific areas, like your vegetable patch or flower beds.

1. Hardware Cloth (Wire Mesh):

This is the gold standard for gopher proofing.

  • How to Use:

    • For Raised Beds: Line the bottom and sides of your raised garden beds with 1/4-inch or 1/2-inch hardware cloth. Ensure the mesh extends at least a foot up the sides to prevent climbing over. Overlap seams by at least 4 inches and secure them with heavy-duty zip ties or wire.
    • For In-Ground Beds: Dig a trench around the perimeter of your garden bed, at least 12-18 inches deep. Bury hardware cloth vertically, ensuring at least 6-12 inches are below ground level and about 6 inches are above the soil surface. Bend the bottom 6 inches of the hardware cloth outward at a 90-degree angle to create an underground “skirt” that discourages burrowing underneath.
    • For Individual Plants: You can create baskets from hardware cloth to plant around sensitive bulbs or young trees.

  • Key Considerations:

    • Mesh Size: 1/4-inch mesh is generally more effective than 1/2-inch as it prevents even smaller gophers.
    • Galvanized Coating: Use galvanized hardware cloth to prevent rust and prolong its lifespan.
    • Installation Depth: Proper burial depth is crucial to prevent gophers from tunneling under the barrier.

2. Other Barrier Materials:

  • Gopher Wire: Specifically designed for gopher exclusion, this is similar to hardware cloth but may have different specifications.
  • Plastic Netting: While less durable and potentially less effective than hardware cloth, some heavy-duty plastic netting can deter shallow burrowers. However, gophers can chew through softer plastics.

Gopher Trapping: An Effective Gopher Removal Method

Trapping is a direct method of gopher removal that can be very effective when done correctly. It is a key component of comprehensive garden pest control.

1. Types of Gopher Traps:

  • Scissor Jaw Traps: These are the most recommended and effective traps for gophers. They have two opposing jaws that snap shut when a gopher triggers the bait.
  • Choke Traps: These traps have a spring-loaded loop that tightens around the gopher.
  • Macabee Traps: A classic design featuring a loop that closes on the gopher.

2. Locating Active Tunnels:

  • Find a fresh gopher mound.
  • Locate the main runway by probing the soil with a stick or wire a few feet away from the mound. You’re looking for a smooth, unobstructed tunnel about 2-4 inches in diameter. The tunnel often runs parallel to the surface.
  • Carefully excavate a small opening into the tunnel. Avoid collapsing the tunnel, as this will make it harder for the gopher to use and trap placement more difficult.

3. Setting the Traps:

  • Placement: Place two traps in the tunnel opening, facing opposite directions. This increases the chances of catching the gopher as it travels either way.
  • Baiting: Gophers are primarily herbivores, so baiting with tempting plant material is best.
    • Preferred Baits: Fresh vegetables like carrots, sweet potatoes, lettuce, or alfalfa. Cut them into small, manageable pieces.
    • Natural Attractants: Some gardeners report success with natural attractants like peanut butter mixed with oats or seeds, but traditional vegetable baits are often more reliable for gophers.
  • Covering the Opening: Once the traps are set, cover the opening with a piece of sod, a sturdy piece of cardboard, or a plastic bucket turned upside down. This blocks out light and prevents other animals from interfering.
  • Checking Traps: Check your traps daily. Gophers are active during specific times of the day, so persistence is key.

4. Safety and Disposal:

  • Wear Gloves: Always wear gloves when handling traps and gophers to avoid transferring scents and for hygiene.
  • Disposal: Dispose of trapped gophers responsibly, following local regulations.

Other Gopher Removal Methods

While trapping is common, other methods are available, though their effectiveness can vary, and some are less humane.

  • Flooding: Flooding tunnels can drive gophers out, but it’s often ineffective as they can create escape routes or simply burrow deeper. It also wastes a lot of water.
  • Fumigation: Carbon monoxide cartridges or other fumigants can be used, but they are toxic and can be harmful to beneficial soil organisms and potentially to pets or children if not used with extreme caution and knowledge.

Integrating Multiple Strategies for Maximum Effectiveness

The most successful approach to garden pest control for gophers often involves a combination of methods. This integrated pest management (IPM) approach maximizes your chances of keeping your garden gopher-free.

1. Proactive Measures:

  • Soil Aeration: Regularly aerating your soil can make it less appealing for gophers to tunnel through.
  • Companion Planting: As mentioned, planting gopher-repellent plants alongside your main crops might offer a layer of defense.
  • Good Garden Hygiene: Remove dead plant debris promptly, as this can harbor pests.

2. Reactive Measures:

  • Observation: Regularly scout your garden for signs of gopher activity (mounds).
  • Targeted Treatments: Address new mounds promptly with traps or natural repellents.
  • Perimeter Protection: If you have a specific area to protect, consider installing hardware cloth around its perimeter.

3. Long-Term Solutions:

  • Raised Beds with Hardware Cloth: This is arguably the most effective long-term solution for protecting valuable garden areas.
  • Persistent Trapping: For ongoing gopher problems, regular trapping might be necessary, especially during peak seasons.

Can I Use Certain Plants as Natural Gopher Repellents?

Yes, some plants are believed to act as natural gopher repellent due to their strong scents or known toxicity. While their effectiveness can vary and isn’t always guaranteed, planting them strategically can be part of a multi-pronged approach.

Plants Known for Gopher Repellency:

  • Castor Bean Plant (Ricinus communis): Contains ricin, a highly toxic compound. Caution: All parts of the castor bean plant are poisonous if ingested. Handle with extreme care, especially around children and pets. It’s often recommended to plant it around the perimeter rather than interspersing it, or to avoid it altogether if safety is a concern.
  • Gopher Plant (Euphorbia lathyris): This plant’s milky sap is believed to deter gophers.
  • Marigolds (Tagetes species): The strong scent of certain marigold varieties is often cited as a deterrent.
  • Lavender (Lavandula species): Its potent fragrance may be off-putting to gophers.
  • Rosemary (Rosmarinus officinalis): Similar to lavender, its aromatic properties might deter them.
  • Peppermint (Mentha piperita): The strong menthol scent is a well-known repellent.

Important Note on Plant Effectiveness: While these plants are often recommended, scientific evidence for their consistent efficacy is sometimes limited. They work best as part of a broader strategy rather than a sole solution.

How to Stop Gophers from Returning: Sustaining Your Garden’s Protection

Once you’ve managed to deter or remove gophers, the challenge is to prevent their return.

  • Maintain Barriers: Ensure any hardware cloth barriers remain intact and properly buried.
  • Continue Monitoring: Keep an eye out for new mounds or signs of activity.
  • Natural Repellents: Periodically reapply natural gopher repellent sprays or baits to maintain a less-than-welcoming environment.
  • Encourage Natural Predators: While not a direct method, a healthy ecosystem can support predators like snakes, owls, and hawks that naturally prey on gophers. Avoid using broad-spectrum pesticides that harm these beneficial creatures.

Frequently Asked Questions (FAQ)

Q1: Are gophers dangerous to humans or pets?

While gophers are not directly aggressive towards humans or pets, their tunnels can create tripping hazards. Their burrowing activity can also destabilize soil around foundations or patios. If ingested, the castor bean plant, sometimes used as a repellent, is highly toxic.

Q2: How long does it take to get rid of gophers?

The time it takes to get rid of gophers varies depending on the severity of the infestation, the methods used, and the persistence of the gardener. Trapping can yield results within days to a couple of weeks, but it may require ongoing effort to manage new arrivals. Natural repellents may take longer to show effects and require continuous application.

Q3: Can I use ultrasonic devices to deter gophers?

Ultrasonic devices that emit high-frequency sounds are often marketed as gopher deterrents. However, their effectiveness is highly debated, and many studies suggest they have little to no lasting impact on burrowing animals. Gophers can become accustomed to the sounds, or they may simply avoid the immediate area without being truly repelled from the property.

Q4: What is the best time of year to trap gophers?

The best times to trap gophers are typically during spring and fall. During these periods, gophers are more actively foraging as they prepare for breeding or to store food for the winter. Wetter soil can also make it easier to locate their tunnels.

Q5: What if I have a severe gopher infestation?

For severe infestations, a multi-pronged approach is essential. Consider combining effective gopher trapping with robust barriers like hardware cloth for vulnerable areas. You might also consult with a professional pest control service that specializes in humane and effective gopher removal methods.

By employing a combination of natural gopher repellent strategies, effective barriers, and proven gopher trapping techniques, you can significantly reduce and, in many cases, eliminate gopher problems in your garden. Protecting your plants from these determined burrowing animals requires vigilance and a well-rounded approach to garden pest control.
