Measures to Keep Groundhogs Away
Many scare devices like scare tape, lights sensitive to motion, etc., are also available for this purpose. You can also place a device capable of emitting high-frequency noise or pinwheels that spin at high speeds producing vibrations, at the entrance of the burrow so that they get irritated and vacate the place.
Cartridges releasing poisonous gases is another way to tackle this problem. These cartridges must be ignited before being inserted into the burrow, and the entry must be sealed with grass and stones.
When inside, these smoke bombs release carbon monoxide or sulfur dioxide which are toxic gases capable of suffocating an animal to death. This measure must be used on rainy days when a groundhog is not so active, and you are sure of its presence inside the den. This method is not feasible for human dwellings due to the toxic factor associated with it.
All you need to do is to attach a hose to your vehicle's exhaust outlet and insert it inside the burrow. Switch on the vehicle and let the fumes fill the burrow completely. The expelled gases will definitely choke the animal and force it to leave the dwelling. It is better to have a trap at the exit of the burrow so that the rodent gets caught in it.
Groundhogs love to feed on vegetables, fruits, garden plants, etc. This point is noted to devise a trick for their elimination. Sprinkle a decent amount of Epsom salt to impart a bad taste to these eatables. Being picky eaters, groundhogs will leave their den and move to another area in search of suitable food.
However, make sure you wash the eatables thoroughly when you pick them for consumption. To repel these creatures via foul smell, you can either place rugs soaked in ammonia or moth balls inside and at the exit points of the burrow. You can also pour fox or coyote urine in their burrow to scare them.
A chicken wire fence that stands 2-4 feet above the ground and runs about 1 foot deep can be used. To increase protection levels, you can bend the ends of the underground mesh at a right angle pointing towards the opposite side of the garden. This will prevent the entry even if the rodent tries to enter via burrowing.
Place the trap where the rodent visits frequently or right outside the burrow, and carry out this task in daylight when the target moves out in search of food. When the rodent enters the cage to feed on the bait, the door shuts down leaving it trapped. Trapped pests can be released in selected places suggested by local wildlife agencies.
This is a lethal method to eradicate groundhogs. Before using this method, you must be prepared to remove the corpse of the dead rodent once the poison has done its job. If not done on time, the smell will leave you nauseous.
Get some poisonous pellets from local stores and drop them in the burrow. If you buy a liquid poison, pour it directly into the den. Keep checking for signs of death of the rodent. Once confirmed, dispose or bury the corpse appropriately.
This must be the last option to eliminate these undesired pests, as shooting a live organism is not pleasing. If at all you need to take up this measure, make sure your state regulations allow shooting groundhogs in case they have become a problem.
Shooting these rodents is not difficult as these are slow-paced in nature. However, you need to have the patience to look for and chase them when they come out of the den in search of food and water.
Some Useful Tips For You
✔ Plant some vegetation such that it surrounds the entry and exit of the burrow. This will hinder visibility and make it difficult for the groundhog to move in and out of its den, thus compelling it to leave the place.
