Groundhogs (woodchucks) primarily loathe strong, pungent odors, consistent human presence, and predators. The most effective deterrents they hate the most include predator urine (fox or coyote), castor oil, ammonia, and garlic/pepper scents.
To get groundhogs (woodchucks) to leave your yard, start by making your property unappealing. Clear tall grass, brush piles, and seal off spaces under sheds or decks. Apply strong sensory deterrents like cayenne pepper, garlic, or castor oil around burrow entrances to drive them out.
Yes, vinegar can help deter groundhogs, as they have highly sensitive noses and despise the pungent scent. However, it is a temporary fix and must be used carefully so you don't damage your plants or yard.
Groundhogs are repelled by pungent scents that mimic predators or overpower their sensitive noses, specifically castor oil, garlic, cayenne pepper, ammonia, and lavender. Applying these scents around burrow entrances and garden perimeters can deter them from returning, with commercial repellent options like Deer Out and Messina Animal Stopper acting as effective commercial options.
Cayenne pepper – Our Farmers' Almanac readers swear by this method: Simply pour cayenne pepper close to the groundhog's holes. Buy a large container (bulk size) so you can create a small pile. When it rains or is windy, you'll have to reapply. It's actually the smell and the heat they don't like.
If you block a groundhog (woodchuck) hole, the groundhog will simply dig it back open, dig a new exit, or another animal may move into the vacant den. Before blocking any hole, you must verify the den is abandoned to avoid trapping the animal inside, especially during spring when dependent babies may be present.
Groundhogs are one of only a few mammals that are true hibernators. Around late October to early November, groundhogs retreat to their underground burrows to hibernate through the winter. In early fall, groundhogs eat large amounts of food to build their fat reserves in preparation for their long slumber.
Putting mothballs down their holes, or pouring down Clorox is only a temporary cure. Even if they leave, they'll be back.
Groundhogs (woodchucks) are diurnal, meaning they are active during the day. They are most active during the early morning and late afternoon/evening when they leave their burrows to forage for food.
The active ingredient in antifreeze is ethylene glycol, which is a dangerous poison. Each year hundreds of animals, both domestic and wild, are attracted to its sweet taste. When large amounts are swallowed, convulsions and coma occur. Smaller doses can result in irreversible kidney damage.
When deciding how to repel groundhogs, one option is to make your own repellent by diluting hot pepper sauces with water and spraying it on plants. You can also use Epsom salts to get rid of groundhogs, although this tends to wash away easily when it rains.
Mix ammonia with washing detergent, vinegar, hot pepper, and soap and pour the mixture down each hole. This may have to be repeated for a few days until the groundhogs go away.
Answer: There are several effective methods for plugging groundhog holes, including using a mixture of soil and gravel, using a commercial groundhog hole plug, or filling the hole with expanding foam. The best method for you will depend on the size and location of the hole.
The primary predators of groundhogs are hawks, foxes, coyotes, bobcats, dogs and humans. However, motorized vehicles kill many groundhogs each year.
Groundhogs are primarily diurnal and most active during the early morning and late afternoon/early evening. They leave their dens during these times to forage for food, spending the rest of the day basking in the sun or sleeping, particularly avoiding the extreme heat of midday during summer.
Yes, many gardeners and homeowners use Irish Spring soap to deter groundhogs, but its effectiveness is mostly anecdotal and often temporary. Because groundhogs have a very strong sense of smell, the intense fragrance of the soap can act as a mild, short-term repellent.
What's the best way to get rid of groundhogs?
There are no registered poisons specifically manufactured for groundhogs, but they are highly susceptible to general rodenticides (like rat/mouse poison), toxic chemical baits (like mole/gopher bait), and lethal burrow fumigants. Additionally, household items like antifreeze (ethylene glycol) are highly toxic to them.
Sodium Nitrite is fatal to other animals in addition to pigs, so the risk from non-target consumption must be considered. To help prevent consumption by other animals, field tests for sodium nitrite used custom feeders designed to only allow feral hogs to access the bait.
Groundhogs are among the few mammals that enter into true hibernation. Hibernation varies with latitude, but generally begins near the end of October or early November and continues until late February and March.
Groundhogs do hibernate! They are one of the few true hibernators that can also be nuisance wildlife. As the temperatures drop and food sources become limited, groundhogs enter a deep hibernation state to survive the cold winter months.
Michigan's official groundhog, Woody the Woodchuck, predicted six more weeks of winter. Monday marks Groundhog Day, and Woody agreed with what Punxsutawney Phil predicted, after he saw his shadow and predicted there would be six more weeks of winter.
Yes, Epsom salt can help deter groundhogs, but it is not a permanent solution. Groundhogs dislike the bitter taste and smell, but the remedy washes away easily and is considered a mild, anecdotal deterrent rather than a foolproof fix.
Normal household bleach is 6% sodium hypochlorite. You can dilute and let sit out in the sun and it will break down and degrade very quickly. Dilute it in a bucket of water, and you can just pour it out in the grass the next day or really probably sooner. Also, chlorine in normal amounts will not harm a septic system.
A groundhog (or woodchuck) typically lives 2 to 3 years in the wild, though they can occasionally reach up to 6 years. In captivity, away from predators and harsh conditions, their lifespan jumps significantly, ranging from 10 to 14 years.
