Does Flooding a Gopher Hole Work? A Deep Dive into Gopher Control

▶

The short answer is: flooding a gopher hole can sometimes work, but it’s rarely a reliable or effective long-term solution for gopher control. While the immediate satisfaction of seeing water disappear down a gopher burrow is tempting, several factors make it a dubious strategy. It might temporarily displace a gopher, but it’s unlikely to drown it, and it certainly won’t solve the underlying problem of an inviting habitat.

The Limited Effectiveness of Flooding

Flooding rarely achieves its intended goal for several key reasons:

• Extensive Burrow Systems: Gopher burrows are incredibly complex networks, often spanning hundreds of feet and including multiple levels. The water will likely seep into the soil long before it reaches the gopher, especially in well-drained areas.
• Pocket Gophers are Adept Swimmers: Despite living primarily underground, pocket gophers (the species most commonly referred to as “gophers”) are surprisingly capable swimmers. They can hold their breath for extended periods and navigate through flooded sections of their tunnels.
• Burrow Design for Drainage: Gopher burrows are often designed to allow for some degree of drainage, preventing them from becoming permanently flooded during natural rainfall. This built-in drainage system works against your flooding efforts.
• Soil Type Matters: The effectiveness of flooding heavily depends on the soil type. In sandy or loamy soils, the water will quickly drain away. Clay-rich soils might hold water longer, but the gopher could still find air pockets within the burrow.
• Temporary Displacement, Not Eradication: Even if you manage to flood a section of the burrow and force the gopher out, it will likely simply relocate to another part of its extensive tunnel system or, at worst, move to a nearby area of your property.
• Waste of Water: In many regions, water conservation is crucial. Using large amounts of water to flood a gopher hole is often an inefficient and environmentally irresponsible solution.

Ultimately, flooding is a hit-or-miss tactic with a low success rate and potential drawbacks. Focusing on more effective and sustainable methods is generally recommended.

Better Alternatives for Gopher Control

Instead of relying on flooding, consider these more reliable gopher control strategies:

• Trapping: This is often the most effective and humane method. Several types of gopher traps are available, including box traps and scissor-jaw traps. Learning how to properly set and bait these traps is crucial for success.
• Gopher Baits: Baits containing zinc phosphide or strychnine can be effective, but they should be used with extreme caution, especially in areas with pets or children. Follow all label instructions carefully and consider the potential risks to non-target animals.
• Predator Encouragement: Attracting natural gopher predators, such as owls, hawks, snakes, and foxes, can help control gopher populations. Providing suitable habitat for these predators can be a sustainable long-term strategy.
• Gopher-Resistant Landscaping: Using wire mesh around the roots of vulnerable plants and trees can prevent gophers from accessing them. Choosing plants that gophers find less appealing can also help.
• Professional Pest Control: If you’re struggling to control gophers on your own, consider hiring a professional pest control company. They have the experience, equipment, and knowledge to effectively manage gopher populations.

Frequently Asked Questions (FAQs) About Gopher Control

Here are 15 frequently asked questions about gopher control to further inform your gopher management efforts:

1. What’s the difference between a gopher and a mole? Gophers create crescent-shaped mounds of soil with offset burrow entrances. Moles create volcano-shaped mounds and leave raised ridges on the surface. Gophers also eat plant roots and tubers, while moles primarily feed on insects and earthworms.

2. Are gophers harmful? Yes, gophers can cause significant damage to lawns, gardens, agricultural crops, and even underground infrastructure like irrigation lines. Their tunneling can also create tripping hazards.

3. How can I tell if I have a gopher problem? Look for fresh mounds of soil, plugged burrow entrances, and damaged plants. You might also notice tunnels collapsing under your feet.

4. What’s the best time of year to control gophers? The best time to control gophers is typically in the spring and fall when they are most active.

5. Can I use ultrasonic devices to repel gophers? The effectiveness of ultrasonic devices is debated. While some users report success, scientific evidence supporting their efficacy is limited.

6. Are there any natural ways to repel gophers? Some gardeners use castor oil-based repellents or plant gopher-repelling plants like daffodils or gopher spurge. However, these methods may not be entirely reliable.

7. How do I properly set a gopher trap? Consult the trap’s instructions carefully. Typically, you’ll need to locate the main burrow, dig it open, place the trap inside, and cover the opening lightly with soil.

8. What bait should I use for gopher traps? Common baits include carrots, apples, peanut butter, or commercially available gopher bait.

9. How often should I check my gopher traps? Check your traps daily. A trapped gopher should be removed promptly.

10. Is it legal to trap and relocate gophers? Regulations regarding trapping and relocating gophers vary by location. Check with your local wildlife agency for specific rules and permits. In many areas, relocation is discouraged or illegal due to the potential for spreading disease and disrupting ecosystems.

11. How can I prevent gophers from returning after I’ve controlled them? Maintain a well-maintained lawn and garden. Consider using gopher-resistant landscaping techniques and encouraging natural predators.

12. Are there any specific plants that gophers are attracted to? Gophers are particularly fond of alfalfa, clover, and many garden vegetables and fruit trees.

13. Can gophers damage my home’s foundation? While less common, extensive gopher tunneling near a foundation can potentially weaken the soil and contribute to settling or cracking.

14. What are the risks of using gopher baits? Gopher baits can pose a risk to pets, children, and non-target wildlife. Use them with extreme caution and always follow label instructions carefully. Consider using tamper-resistant bait stations.

15. How much does professional gopher control cost? The cost of professional gopher control varies depending on the size of the area, the severity of the infestation, and the methods used. Get quotes from multiple companies to compare pricing.

While the idea of flooding a gopher hole might seem like a quick and easy solution, its effectiveness is questionable at best. A combination of strategic trapping, habitat modification, and professional assistance (when needed) will offer the most effective and sustainable approach to managing gopher problems. Remember to always prioritize safety and environmental responsibility when implementing any gopher control methods.
