When you talk of a groundhog most people probably think that they only eat plant-based food like tomatoes, squash, grass, and flowers.
But they do also eat animals, just not as much as greens!
Groundhogs will eat other animals but mainly in the form of smaller insects as a source of animal protein, but they have also been observed to eat eggs and smaller rodents and bird nestlings. However, they are not considered dangerous to humans or pets.
It is important to remember that groundhogs don’t actively hunt as they are mainly (though not entirely) herbivores, but mainly seek out the animals that appear in their foraging for other foods or when digging.
They behave similarly to gophers and prairie dogs that are fairly close relatives to the groundhogs. These rodents also don’t eat a major amount of animals, and it seems like the relative amount diminishes with size. So the gopher is probably the least meat hungry of the three.

What Insects do Groundhogs Eat?
They mostly eat insects that they find in the ground when they are digging or under bark from older trees. Insects are most important for the groundhog’s diet in the spring and early winter when plant food is scarce.
They eat mostly slower insects, such as slugs, snails, beetles, and worms, as their sight is bad and they are not fast enough to catch, for example, flies or dragonflies.
Do Groundhogs Eat Mice and Rats?
No, Groundhogs are not known to eat adult mice or rats, but they may eat younger mice or weaker ones that cannot run away if the groundhog is given the chance.
They rarely eat other rodents though, as this is an evolutionary instinct to prevent diseases from infecting them as many diseases are shared within the rodent family.
Would Groundhogs Kill and Eat Chickens?
Groundhogs are not known to kill or eat chickens. They may try to kill baby chicks in chicken coops if they are given the opportunity but most groundhogs will not go near a full-grown chicken.
However, they may be hazardous to chicken eggs. If they come across an egg and it is cracked, they might try to eat it. A groundhog can pretty much eat any type of animal food that we humans will, so if you have a chicken coop just be sure to get all of your eggs before the groundhog gets there.
Do Groundhogs Attack Pets Like Dogs and Cats?
Groundhogs are not aggressive to pets unless you have a close, prolonged encounter with them. However, compared to gophers, they are bigger and have a higher chance of offending pets.
They are usually more scared of the pet than the pet is of them.
They may growl at dogs but this is not meant as an attack. Groundhogs are also very good climbers and they can actually climb trees if necessary. They also often have a hole that they have dug nearby to hide in.
This makes it difficult for dogs or cats to catch them.
Groundhogs often encounter cats and dogs when they are out foraging for food in people’s backyards. They will usually flee and hide if they come face to face with a large, four-legged predator.
On the contrary dogs and cats are the ones that can attack groundhogs, so be careful when letting them loose in your yard!
However, they are usually not in danger from the pets unless they are cornered.
Will Groundhogs Eat Other Small Animals?
The only small animals that are known to be regularly eaten by groundhogs are insects such as grasshoppers, worms, and beetles.
When they come across small insects such as grasshoppers they will usually try to catch them and eat them right away.
Groundhogs will usually encounter insects when digging their underground caves. The eggs of ground-dwelling insects are often located very close to the surface of the ground, so a groundhog would have a much easier time catching it than beetles or grasshoppers, and they are nutritious too.
To keep groundhogs out of your home compound or chicken coop, simply put up a fence or barrier that is at least 2 feet tall.
They are pretty good climbers but they cannot climb over something this size. If groundhogs are already living on your property be sure to clean up any fallen fruit around the area.
See my lists of ways to keep groundhogs out of your yard in my previous post here or at the end of this post.
Are Groundhogs Aggressive to Humans?
Groundhogs are not normally aggressive to humans. They will make loud noises, sometimes hiss at you, and maybe even try to nip at us if they feel threatened or cornered. But their small teeth usually cannot make a puncture wound that is very deep.
When they are with their children it is important to keep your distance. They can feel territorial and become defensive when their young are nearby.
When they feel that something dangerous is near, they stand on their hind legs and try to get a good look at the potential threat. Their only real weapon is their mouth, which they use for digging burrows, taking food apart, and warning other animals away.
Groundhogs are not the fierce creatures that we see in stories and movies. They do not attack people unless they feel threatened or if they think you will harm their children. But there is one other type of groundhog that can be very dangerous to humans.
If you live near wooded areas, chances are that you have seen the groundhog at least once in your life. They are usually around during the spring or fall months because that is when they search for food to store up for winter.
How to Prevent Groundhogs from Entering your Backyard?
There are several ways to prevent pests like groundhogs and gophers from invading your backyard. I have listed som of my favorites below.
1. Using ultrasonic sound devices
Groundhogs, like other bigger animals that may invade your garden, tend to have a very good hearing. This means that loud or consistent noises will scare them away or at least shorten their visits.
These are my favorite ultrasonic emitters. Click to see the price on Amazon.
One of my favorite technologies to keep pests away from my backyard is these cool solar-powered ultrasonic sound emitters that you can buy from Amazon.
In my experience, they really work, and the solar panels on top save you the time and money of changing batteries all the time. So probably the easiest solution listed here.
This may, however, not be the best solution if you have pets like dogs and cats, as they will get scared by ultrasound as well.
2. Fencing
You can make a fence in your garden using pie plates, wires, and/or plastic mesh to prevent the groundhogs from getting to your fruit. Make sure that it can’t be dug under, climbed over, or squeezed through.
The best fencing material for this purpose is a cattle panel or hog panel as they are very sturdy and can withstand even quadruped animals such as goats, cows, and deer. However, most chicken fencing types will do.
3. Using Scarecrows
Scarecrows placed near your fruit trees can keep the groundhogs away for a while. You may want to change them every couple of days or so because the groundhogs will realize they’re fake and not be scared anymore.
4. Using Reflective Materials or Light
Groundhogs do not like light, so a great way to deter them from your tomato plants is by using lighting around the area. These come in many forms with solar panels etc. but you can use anything that will provide strong light over a large area, such as lanterns.
The Broox Solar Animal Repeller uses light and ultrasonic sounds to deter animals from your garden.
Compact discs (CDs) are a great way to keep groundhogs away from your tomato plants. They act as reflective surfaces so that when the groundhog approaches, it will see its reflection and leave the area. This is because they think there is another animal in the area with them.
5. Using Traps
You can make a simple cage trap with a wire mesh, a piece of cardboard, and some fruit inside. Make sure that you place this somewhere safe for pets and out of the way.
You can also just buy a live trap, as the sturdy metal ones shown here:
A live groundhog trap is a humane way to get permanently rid of groundhogs in your yard.
A version with thick gloves for safe handling.
6. Using Poison
Using poison is not recommended as it can kill groundhogs, your other wildlife, and pets that may be nearby or that you own. Only use this as a last resort because there are better ways to keep them away from your fruits than harming them and making their families suffer too.
7. Use Motion Activated Sprinklers
Like most animals, groundhogs hate surprises, and they will run away if suddenly sprayed with water. I like this solution because it is humane, simple, effective, and does not require much time to set up. Having a motion-activated sprinkler is a very efficient solution, but does require a garden hose.
My favorite sprinkler option here is the Havahart 5277.
The Havahart 5277 is a motion-activated sprinkler that is activated by the movement of animals up to 25 feet away and sprays them with a harmless water jet, frightening them off and keeping them at bay. The included metal stake makes it easy to install in your garden, and the sprinkler can be rotated 180 degrees for maximum coverage.
This may, however, not be the best solution if you have pets like dogs and cats, as they will get scared as well if you let them outside.
In conclusion:
Groundhogs are actually omnivores rather than herbivores. They have a diet that consists of vegetation, eggs, and small insects. However, they are not aggressive to humans most of the time unless they feel threatened or if they think you will harm their children.
They are not known to eat chickens, but they might try to eat their eggs. They are not aggressive to pets unless you have a close, prolonged encounter with them, but they might eat their food!
