JT Eaton Bait Blocks

  • Also works for squirrels, chipmunks, mice, and rats
  • Easy to use
  • 144 blocks per container

Cons

  • Can take up to a week of consumption for results
  • Dangerous to pets and children

OUR VERDICT

We like the amount of bait in this bucket as well as the effectiveness. This is ideal for people who have an ongoing or chronic problem with gophers and/or other rodents.

Our Review

When gophers are tearing up your lawn and garden, you want them dealt with quickly and permanently. If they’re inviting themselves to your yard, invite them to a picnic featuring JT Eaton Bait Blocks. With the active ingredient diphacinone, these specially formulated peanut butter flavored blocks attract gophers and eliminate them after they feast.

The blocks are ideal for placing throughout your lawn and garden, and inside gopher tunnels. Placing a multitude of blocks inside the tunnel and topping the entrance with a heavy board or brick should ensure the end of that nuisance.

The pail comes with 144 blocks and a tamper evident resealable lid. JT Eaton even offers a 1-year limited warranty to protect against defects. Family owned and operated since 1932, JT Eaton strive to manufacture and sell only the highest quality products available.

Wear gloves each and every time you place bait blocks or whenever disposing of dead rodents. Be sure to keep this bait out of reach from children and pets.

Tomcat Mole Killer Worm Bait

Pros

  • Effective against groundhogs and other burrowing rodents
  • Works within a few days
  • Only takes a single feeding
  • Visually appealing lure.
  • Rated highly by users
  • Made in the USA

Cons

  • On rare occasions, ineffective with a single use
  • A smaller amount of bait than some products
  • Caution must be used regarding children and pets

OUR VERDICT

The visual food lure of a food source (earthworm) and high ratings make this our favorite worm bait. This is a fantastic option for those who only need a small amount of bait, or who tried other poisons with little success.

Our Review

We like Tomcat Mole Killer Worm Bait for its intelligent design. This poison is shaped like an earthworm, which is an occasional addition to a groundhog’s diet. While groundhogs eat mainly vegetables and grasses, they will supplement their food supply with snails, worms, or grubs.

This is an ideal bait for those who only have a couple of groundhogs to deal with and do not need a large container of poison. To use this worm bait, first, check for active groundhog tunnels. Only 10 worms come in a package, so be sure you have active burrows first. While wearing gloves, place the “worm” deep into an active groundhog burrow where pets or a child cannot reach.

As another method, you can poke a tiny hole in the roof of a groundhog burrow, place the worm inside, and then recover the gap with a stone or bit of sod. Recheck the tunnel for activity a couple of days later. Be sure always to wear gloves when disposing of dead rodents or groundhogs and do so within health law guidelines.

Identifying Groundhogs and Their Burrows

Sometimes a groundhog can be confused with other large rodents such as moles. Groundhogs burrow roughly two to four feet below ground. Their burrows can extend up to 15 to 25 feet. These underground homes often have two to five entrances/exits that will measure roughly six to eight inches with a fresh mound of earth around them.

Additionally, groundhogs have larger heads than moles. A groundhog will tend to measure about 15 to 20 inches in length and have grayish-brown fur with a stout body and stubby legs. Groundhogs tend to emerge in the early morning and in the evening, during these daylight hours, to feed. If you’re a dog owner, this can be troublesome if your dog spots the groundhog and goes nuts every time this burrowing animal emerges.

What Groundhogs Eat

Groundhogs come out to feed mostly during the early morning and evening daylight hours. They feast primarily on grasses and vegetables. Occasionally, they will also consume grubs, worms, and snails. If you have fruits and vegetables within their reach, woodchucks can take out a whole garden in one day.

They can also cause massive damage to agricultural crops and will eat berries, corn, apples, carrots—nearly any edible fruits and vegetable they have access to.

How to Catch a Groundhog

If you have tall grass or an ample garden for groundhogs to feast on, it can be helpful to cut your grass short, and harvest your garden in the lower areas groundhogs can reach. This is by no means necessary, but reducing their food supply will make baiting these animals easier.

If you have pets, keep them inside during times the groundhog might emerge to feed on the bait, so they aren’t scared off before they get to it.

Adding to Bait

Even when using bait with an enticing lure, you can always add food to the mix to make it more appealing to groundhogs. Sweetly scented fruits like cut strawberries or cantaloupe work particularly well as a groundhog lure. If you mix bait blocks, granules, or even a bait “worm” in with just a little fresh fruit, you’ll increase your chances of getting woodchucks to eat the bait.

Check After Setting

After groundhog bait is set, wait a couple of days and check the area for signs of activity or dead rodents. Most poisons will take two to three days to work, although some will be effective within one full day. Depending on your situation and the constitution of the animal, it may take a couple of doses.

Regardless, use the utmost caution when setting bait. Keep in mind other animals will likely find these baits appealing, too, especially if mixed with fresh food. So, be sure to apply the poison deep within a groundhog tunnel and out of reach from kids and pets. Once you find a dead rodent, wear gloves and dispose of them quickly according to health laws in your area.

Summary

Groundhogs will often burrow deeper than animals such as moles and more often near trees, under decks or porches, even under homes on a slab. This means they hold the potential for very expensive costs in damage not only to crops and gardens, but also to decks, tree roots, and underground wires or plastic piping.

Live traps or calling a pest professional are options. However, if you’re tight on funds or do not have a place to relocate a live animal, these baits are an affordable, straightforward option. Be sure to use the proper cautionary measures, bait properly, and you should have a groundhog-free yard in a short time.
