    But first, you can watch this video to understand why groundhogs are so hard to get rid of!

    What Is a Groundhog Repellent or Deterrent?

    A groundhog repellent or deterrent is exactly what it sounds like. It can be a spray, granule, or ultrasonic device which keeps groundhogs, also called woodchucks, away from certain patches of land. Many people use them around their garden, outdoor sheds, vegetables, or other potential targets.

    But before you decide to target your groundhog problem with repellents, double check that groundhogs are really the pests that you’re dealing with.

    How Do Repellents Work?

    After you ensure that groundhogs are the problem, you have to choose the right repellent. Most repellents which are sprays or granules, produce an odor which is unpleasant for groundhogs.

    The animal will smell it and be deterred from approaching the plants beyond the barrier. Some also contain materials which are toxic when ingested and could hurt the groundhog, like ammonia.

    An ultrasonic deterrent is different. These small devices supposedly emit a high-pitched sound on a frequency humans can’t hear. It’s extremely unpleasant and groundhogs will avoid them as much as possible.

    Chemical vs. Ultrasonic

    The main difference between these two options are the inherent risk for the groundhog or the plants near the repellents. Chemicals are more effective but some can be harmful to animals and humans. Sometimes they will leave toxic byproducts behind as well.

    Ultrasonic repellents or deterrents are more expensive but don’t include toxic elements. However, scientists are still undecided about whether they actually work or not, which can be bad news for the homeowner who invests in one.

    These repellents use noise or ultrasonic pulses in the ground to scare away groundhogs.

    What Are the Risks of Repellents?

    As with any repellent, there is always the risk of chemicals being ingested or sinking into the soil in the area where it is applied. Nowadays, a lot of deterrents are non-toxic, but users should always be wary of ingredients like ammonia.

    There is also a chance that the groundhog will ignore the deterrent. If this happens, then your garden and plants are still at risk of being eaten. Most pest control experts recommend trying a different repellent in this case or spraying some type of pepper spray on plants that are being nibbled.

    How to Use a Repellent

    Most repellents come with instructions that should be followed to the letter. Failing to do so can result in unintended and unpleasant consequences, such as ingesting toxic chemicals or even attracting a different form of wildlife. For instance, coyote urine might bring different visitors to the yard.

    As with most outdoor pest control products, be sure to read the instructions and follow them carefully.

    Know Your Enemy

    One of the most important steps to using any form of repellent or deterrent is to know your groundhog’s habits. If you have a creature that really likes your vegetable garden, than the repellent needs to be near that area.

    If your friendly neighborhood woodchuck constantly digs under the garden shed, then the deterrent should be placed there instead.

    Do Groundhog Repellents Work?

    Groundhog repellents are a mixed bag. Some of them work, but others don’t seem to have the desired effect. The most common reason for a deterrent not working is that the woodchuck itself is simply too determined or tenacious to be stopped by a spray or noise.

    If this is the case, consider looking into a groundhog trap to catch the persistent pest.

    How Much Does a Deterrent Cost?

    Most woodchuck deterrents are relatively inexpensive. Almost all products contain multiple uses and are guaranteed to last for at least two weeks to a month.

    Some ultrasonic repellents will be more expensive, but they last closer to six months.
