How to Get Rid of Groundhogs
You can use natural repellents, traps, scare tactics, gas cartridges, or your gun to get these furry, hole-digging lovers of vegetables and flowers off your land. Then, take steps (in-ground fencing, for example) to keep them away.
Understanding Groundhogs
Are groundhogs a friend or a foe? Groundhogs can be both. While they may make their presence known through burrows, they can also provide an important service by preying on garden pests. But if the groundhog activity becomes a nuisance and threatens gardens or home foundations, it’s important to remove them.
What are groundhogs?
Groundhogs, also known as woodchucks or whistle pigs, are a species of large rodent native to North America. They are usually grayish-brown and have small heads, short ears, and small eyes.
Groundhogs typically reach lengths of 20–27 inches (51–69 cm) and weigh around 6–10 lbs (2.7–4.5 kg). They are usually found in fields and wooded areas and can cause damage to gardens, lawns, and home foundations.
What attracts groundhogs?
Groundhogs are attracted to gardens and lawns because of the availability of food. They like to feed on clover, dandelion, alfalfa, and other plants found in these areas. Groundhogs also like to burrow near homes and yards for shelter.
Additionally, groundhogs are attracted to areas with water since they enjoy wallowing in shallow pools of water. This can be a problem as they often create holes near water sources and damage them.
11 Ways How to Get Rid of Groundhogs
1. Use Repellents: Repellents are one of the most effective ways to get rid of groundhogs. They work by emitting a smell or taste that the groundhogs find unpleasant, making them want to leave the area. Several types of repellents are available, including predator urine and commercial products containing mothballs or peppermint oil. You can also make use of repellers such as PredatorGuard’s Pestaway Ultrasonic Animal Repeller, which instantly scares pests away with a motion-activated blast of ultrasonic sound and strobe lights. 2. Install Fencing: Installing a fence around your garden or yard can effectively keep groundhogs out of unwanted areas. Choose a fence at least 4 feet (1.2 m) high, and ensure it has no gaps larger than 1 inch (2.5 cm). It should also be buried at least 8 inches (20 cm). 3. Trap Them: If you have a groundhog problem, trapping them can be an effective way to get rid of them. You can buy live traps that lure the animal in with bait and then trap it without harming it. Once caught, you can release the groundhog at least 3 miles (4.8 km) away from your home or garden. 4. Use Natural Predators: Groundhogs are preyed upon by natural predators such as foxes, coyotes, and hawks. Encouraging these animals to live in and around your yard can help to reduce groundhog populations. Planting native shrubs, keeping bird feeders in your yard, and maintaining a healthy bird population can all help to attract these predators. 5. Eliminate Food Sources: Groundhogs are attracted to areas with abundant food sources, such as gardens and lawns. To reduce the amount of groundhog activity in your yard, try to eliminate easy food sources such as fallen fruit and nuts from trees. Be sure to keep bird feeders away from areas where groundhogs may be present. 6. Remove Groundhog Burrows: If you notice a groundhog burrow on your property, removing it as soon as possible is important. The best way to do this is to fill in the entrance with dirt and rocks. This will encourage the groundhog to find a new home away from your property. 7. Remove Debris: Groundhogs like to hide and nest in areas filled with debris such as leaves, sticks, and wood piles. Removing these items can help reduce groundhog activity in your yard. 8. Use Solar-Led Lights: Groundhogs are nocturnal animals, so they tend to avoid areas with bright lights at night. Installing Solar-Led Deterrent lights around your property can help to keep groundhogs away. 9. Plant Repellent Plants: Planting certain plants in your garden or around your yard can help deter groundhogs from entering the area. Some good options include pennyroyal, garlic, and chives. 10. Use Exclusion Devices: If you have a groundhog problem, you can use exclusion devices such as one-way or two-way doorways to keep them out. These devices are designed to allow groundhogs to leave but not reenter the area, giving you an easy way to get rid of them without resorting to trapping or poisoning. 11. Use Sprinklers: Groundhogs don’t like getting wet, so you can use sprinklers around your yard or garden to keep them away. Motion-activated sprinklers are a good option as they will only turn on when the groundhog is present, deterring it from entering your yard or garden.
What damages can groundhogs do?
Groundhogs can cause a variety of damages to your property. They are known to dig deep burrows and tunnels that can weaken the structure of buildings, patios, decks, retaining walls, and foundations.
Groundhogs also love to feed on garden plants and vegetables and can quickly strip away all of a garden’s vegetation in just one night.
In addition, they can carry diseases such as rabies and ticks, which can harm humans. Finally, groundhogs are notorious for chewing on outdoor wiring, leading to costly repairs.
How to prevent groundhogs from coming back
1. Maintain Your Property: Regularly inspect your property for signs of groundhog activity and repair any damage you find as soon as possible. This will help to deter groundhogs from making a home on your property in the future. 2. Trim Bushes and Fences: Groundhogs like to hide in overgrown bushes and fences, so be sure to trim these items regularly. This will also help you spot any signs of groundhog activity more easily. 3. Check for Entry Points: Groundhogs can fit through surprisingly small gaps, so inspecting your property for any potential entry points they could use to get inside is important. Seal any small openings with mesh wire or expanding foam to prevent groundhogs from returning. Groundhogs can cause a lot of damage to your property, so it’s important to take steps to get rid of them. By eliminating food sources, removing burrows and debris, using Solar-Led lights, planting repellent plants, and using exclusion devices or sprinklers, you can prevent groundhogs from entering your yard and help protect your property from future damage.
Frequently Asked Questions:
What do groundhogs hate? Groundhogs dislike loud noises, bright lights, strong smells, flowing water, or tight spaces. They also dislike certain plants such as pennyroyal, garlic, and chives which can be used to keep them away from your property. What smell do groundhogs hate the most? Groundhogs hate strong odors such as ammonia, garlic, vinegar, and predator urine. Spraying these scents around your property can help to deter groundhogs from entering the area.
Additionally, you can also use commercially available repellents to keep groundhogs away.
What home remedy kills groundhogs? No home remedy will effectively kill groundhogs. The best way to eliminate them is by trapping or using exclusion devices such as one-way doorways. You can also use various deterrents, such as Solar-Led lights, repellent plants, and sprinklers, to make your property less appealing to groundhogs. How do I get rid of a groundhog under my shed? The best way to remove a groundhog under your shed is by using an exclusion device such as a one-way door. This will allow the groundhog to leave but not reenter the area, giving you an easy way to eliminate them without trapping or poisoning. Alternatively, you can also use deterrents such as Solar-Led lights.
How to Get Rid of Groundhogs
Besides bringing news of a longer winter or an earlier spring, cute, furry groundhogs can destroy your lawn and garden. So, how do you get rid of groundhogs?
You can use natural repellents, traps, scare tactics, gas cartridges, or your gun to get these furry, hole-digging lovers of vegetables and flowers off your land. Then, take steps (in-ground fencing, for example) to keep them away.
But first, let’s take a closer look at groundhogs and the damage they can cause.
What are Groundhogs?
Groundhogs, also known as woodchucks or “whistle-pigs,” are a type of rodent called a marmot, a member of the squirrel family. Although related to ground squirrels, they grow to be much larger — about 2 feet in length and 10 pounds in weight.
Primarily herbivores, they will occasionally eat smaller rodents and insects. Brown with round bodies, ever-growing teeth, and long, strong claws used for digging their burrows, groundhogs can live up to six years in the wild. They make their homes in the wooded areas of the United States, parts of Alaska, and Canada.
How to Identify Groundhog Damage
Groundhogs hibernate from October through early February. When awake, groundhogs burrow, mate, and forage for food. Homeowners should look for signs of groundhog damage, including:
- Teeth marks
- Claw marks
- Damaged plants
- Dirt mounds
- Burrow holes
Keep in mind that these are also the hallmarks of other critters like moles and voles. Once you’re sure groundhogs are your culprit, and especially if they have burrowed beneath your garage, shed, foundation, or other structure (which can cause a host of issues), it’s time to send them packing.
How to Get Rid of Groundhogs
Whether groundhogs are rifling through your garden or burrowing underneath your foundation, deck, or shed, try these methods of ridding the nuisance from your land.
1. Use Natural Groundhog Repellents
There are no commercial chemical repellents specifically to control groundhogs, but pesticides targeting other rodents placed at the entrance to a groundhog’s hole reportedly will work.
Natural repellents that some people swear by include:
- Spray coyote, fox, or dog urine: Spray, drizzle or pour this near a groundhog’s hole to repel groundhogs. They fear predators, including coyotes, foxes, and dogs, and smelling their urine is a warning to stay away. If you don’t have a dog, some people claim putting used kitty litter just inside a groundhog’s hole will ward off this pest.
- Spread dog fur and human hair clippings: Groundhogs dislike people and man’s best friend is a foe, so sprinkle some of Fido’s fur or hair collected from a salon or barber shop around your flower bed to deter groundhogs.
- Use ammonia: A rag soaked with ammonia placed near the entrance of a groundhog’s hole acts as a giant “Keep Away” sign. Other strong scents groundhogs don’t like include talcum powder, mothballs, Epsom salt, and garlic.
- Use red pepper: Groundhogs, like many people, don’t like spicy foods, so sprinkle red pepper flakes or cayenne pepper, or spray a mix of water and chopped peppers near groundhog tunnels and holes. You’ll have to reapply your pepper flakes or pepper spray after rain.
- Fertilize with blood meal: This groundhog repellent also does your plants good, as blood meal is an organic fertilizer. Consider this a win-win — the groundhog will be gone and your vegetables will be healthier.
- Avoid antifreeze: Don’t try this, as antifreeze as a poison for groundhogs is a myth. While one farmer says it works, experts say it doesn’t. Don’t waste your time.
2. Trap and Release Groundhogs
Here’s how to live trap a groundhog (humanely):
- Set your live trap close to but not blocking the burrow entrance.
- As bait, use a slice of cantaloupe or other fruit. (Replace the bait daily, as fresh bait works best.)
- Once trapped, it’s recommended that you release your groundhog away from your yard (obviously) and away from cities, towns, and other populated areas. If you are releasing the groundhog on private property, get that owner’s permission. Check your state’s laws covering releasing a trapped groundhog.
Pro Tip: Check state rules on groundhog traps. Cage-type traps are recommended, and body-gripping may not be allowed. Foothold traps require special skill and experience.
Note: Trapping is not favored as a method of groundhog removal. According to the University of New Hampshire Extension, “Several factors make this a less attractive approach than you may think: Translocating a woodchuck from its home is subjecting the humanely trapped animal to a prolonged, very stressful ordeal that often ends in its death.”
It’s also possible you may inadvertently trap other wildlife, or that the captured groundhog might be carrying rabies.
3. Target the Groundhogs’ Home
The Humane Society recommends making the groundhogs’ home inhabitable (flooding and fumigation are two examples) to get them to leave.
Flooding
Groundhogs don’t like a wet den (who does?), so flooding works to get groundhogs out of their home and looking for drier land on which to dig their extensive tunnel systems.
Fumigation
Gas your groundhogs. The Missouri Department of Conservation suggests fumigating burrows with cartridges available at your neighborhood farm or home supply stores. Gas cartridges release carbon monoxide in lethal amounts in a groundhog’s burrows.
How to plug a groundhog hole:
- For fumigation to be effective, seal the groundhog’s holes so the pest can’t escape.
- Once you’ve placed the gas cartridge in the groundhog’s entrance, seal the burrow.
- Watch for nearby holes. If you see smoke, seal those, too.
Note: Gas cartridges contain combustible materials, so don’t use them near buildings. Also, don’t breathe the smoke from the cartridges.
4. Use Scare Tactics
Most attempts at frightening groundhogs don’t work well. Scarecrows that are moved around regularly or used on scarecrow sprinklers can offer temporary relief, but they don’t work long-term to frighten groundhogs into digging up someone else’s yard.
Ultrasonic noise and vibrations can scare away groundhogs, moles, and other digging pests. Solar stakes that send ultrasonic pulses cause the ground to vibrate. The shaking leads groundhogs and other nuisance pests to seek safer quarters elsewhere.
5. Shoot Them
Yes, you can remove groundhogs and other nuisance pests with a gun in Missouri and other states. The Missouri Department of Conservation recommends checking with local authorities regarding firearms use and adds this note: “A young, medium-sized, properly prepared groundhog makes excellent table fare.”
How to Prevent Groundhogs from Moving in
Once you’ve said goodbye to your groundhog problem, here’s how to keep them from returning:
1. Build Fences
An in-ground fence is your best option for keeping groundhogs away from vegetable gardens and flower beds. The PennState Extension suggests a fence at least 3 feet high and buried 12 inches underground. Chicken wire or another sturdy wire fencing material is best to keep groundhogs, gophers, and raccoons out of your space.
“As an additional measure, place an electric wire 4 to 5 inches off the ground and the same distance outside the fence,” the Extension office advises. “When connected to a fence charger, the electric wire will prevent climbing and burrowing.”
You can also use hardware cloth buried 1 foot into the ground to deter groundhogs from burrowing under decks, foundations, and the like.
Pro Tip: Before installing any type of fencing or barrier, make sure there aren’t any inhabited burrows nearby. You don’t want to accidentally trap groundhogs inside and cut off their food and water.
2. Maintain Your Yard
Regularly trimming grasses, shrubs, and trees removes cover groundhogs use to evade predators. If sufficient cover no longer exists in an area, groundhogs may feel less safe and set out in search of a new home.
3. Use Plants as Deterrents
Plants with strong fragrances, such as lavender, will keep groundhogs out of your garden. The Farmers’ Almanac says groundhogs also dislike the smell of these herbs:
FAQ About How to Get Rid of Groundhogs
So, you think you know groundhogs? Maybe. Let’s see if you know the answers to these frequently asked questions. If you miss all of these, well, you’ll have to read the questions again and again until you can answer them correctly, sort of like the movie “Groundhog Day.”
Before deciding to get rid of groundhogs, understand that unless they’re causing a problem, they should be left alone.
Groundhogs play an important role in our ecological system. Their abandoned burrows can become homes for other wildlife, such as foxes, skunks, and rabbits. They provide food for predators, including hawks, owls, coyotes, and eagles. Their occasionally problematic digging can even help aerate the soil and recycle nutrients.
Like their squirrel and chipmunk brethren, groundhogs also don’t reproduce rapidly. Only socializing with a partner when it’s time to mate, adult females carry their young for about one month before giving birth to two to six pups. So, “infestation” isn’t a word you’d associate with these animals.
Groundhogs spend most of their time inside their burrows, emerging a few hours during the day to gather food. When they are out and about, they do their best to avoid humans.
If you happen upon a rabies-infected groundhog, it may attack unprovoked. Other than rabies, groundhogs are not considered harmful to people and do not usually transmit other diseases to them.
When is the Best Time to Try to Get Rid of Groundhogs?
The best time to plug a groundhog’s hole as a removal method is between July and late September. You don’t want to be ousting a groundhog right before hibernation nor during the time females are pregnant and raising their young.
How Do I Get Rid of Groundhogs Under my Shed?
To get rid of groundhogs under your shed, use the same tactics to get rid of them from any other part of your land. Around the perimeter of your shed, try the following DIY methods:
• Spray predator urine
• Spread dog or human hair clippings
• Use ammonia or red pepper
Why is a Groundhog Called a Whistle-Pig?
If you have ever heard a groundhog screech when alarmed, whistle-pig makes perfect sense. Scientific American notes that a groundhog emits a high-pitched whistle as a warning to other groundhogs in the area.
And what is the origin of the woodchuck name? It doesn’t have anything to do with wood. “Wuchak” is what the Algonquin called a groundhog.
When to Call a Pest Control Pro
If your groundhog problem needs more attention than you’re able to give, call in a wildlife pest control professional. A licensed expert will assess your property for signs of groundhogs and create a custom plan to help you get rid of them.
