OUR VERDICT

Kaput Gopher Bait uses the most effective ingredient in the battle against groundhogs and makes application simple and easy.

Our Review

Like many other products, Kaput Pocket Gopher Bait uses diphacinone as the active ingredient. Diphacinone makes this product ideal for all burrowing rodent species and works to attract the pests so they want to eat the poison. Place the pellets inside the tunnels and around your property and let nature take its course.

It can take several weeks to drive groundhogs out of your yard and stop them from building new tunnels. Re-application may be necessary in certain situations.

Rat poison works for groundhogs and it is legal depending on state law. Wear gloves when applying bait.

Identifying Groundhogs and Their Burrows

Groundhogs (or woodchucks) tunnel roughly two to four feet underground. Their burrows can range up to 15 to 25 feet long. A groundhog’s underground home will usually include two to five entrances that measure around six to eight inches. You will see a fresh mound of earth around them in most active groundhog openings.

If you’re unsure whether it’s a groundhog or a mole, groundhogs can be identified by larger heads and bodies and will often burrow near trees or foundations of buildings. A groundhog will tend to measure about 15 to 20 inches in length and have grayish-brown fur with both a stout body and legs. Groundhogs tend to emerge and eat in the early morning and in the evening hours. Moles tend to have narrower faces.

What is in a Groundhog’s Diet?

A groundhog will consume almost any edible fruit, vegetable, legume, or grass it can reach. This can cause expensive damage to farm crops and residential gardens and in a short time. These large rodents primarily eat greens, lettuces, berries, and vegetables such as carrots or corn, they will also consume worms, grubs, and even snails.

How to Kill a Groundhog

Making food as scarce as possible will help lure a groundhog to poison bait. This isn’t always doable in places such as farms. However, if you have a garden and can harvest a lot of the food within reach of a groundhog, and cut your grass short before setting bait, it will leave them fewer options for food. This will make lure bait poison more appealing.

Setting Bait Poison

Once you’ve identified a woodchuck burrow, use disposable gloves to place your bait. Be sure you follow all of the instructions for your selected product carefully. Generally, you can insert the poison deep into the opening of the burrow (use caution, a flashlight is a good idea).

Another option is to follow the direction of the tunnel a couple of feet and poke a small hole in the roof of the burrow, pour or place the bait inside, and then close the roof hole with a rock or sod.

Using Caution

It’s vital to use extreme caution when using groundhog poison. Keep it out of reach from any children, neighbor kids or dogs, and pets of your own. Most rodenticides can make people and pets either very ill or cause death if consumed. So, wear gloves, and dispose of dead rodents quickly, as the poison will still be in the body.

Follow your local health laws for getting rid of dead animals. If you have cats or dogs, it’s vital to dispose of the dead animals immediately, as the poison will still be in their body. Having your own animal get near to investigate is not something you want to happen.

Summary

Groundhogs can cause expensive damage to not only crops and gardens, but also to decks and the foundation under your porch or homes without basements. They’re not just a nuisance in the yard, this can cause problems with underground wires and plastic pipes.

It’s imperative to take care of a groundhog problem quickly. You can always try out live traps or call a professional. However, if your resources are tight or you aren’t home often enough to humanely deal with a live trap, poisons are an affordable option. Furthermore, they can prevent thousands of dollars in damage.
