Moles can quickly take a toll on the beauty of your backyard and garden area. Even though they’re not particularly interested in eating your tomatoes, carrots, roses or even the grass on your lawn, they can still destroy them by burrowing beneath your soil in a frantic search for earthworms.

Getting rid of moles, especially if you only have one or two in your yard every once in a while, usually doesn’t require professional help. In many cases you don’t need to trap or kill them either. With the right mole deterrent, you can get moles out of your yard and keep them out.

How to Keep Moles Away

If you look online for ways to get rid of moles, one of the first things you’ll probably see is some sharp, pointy looking traps. Products that contain poison designed to kill the moles in your yard are probably second to pop up in your search.

There are other options to get rid of moles in your yard without killing them. In fact, there are a wide variety of deterrents that are effective in a lot of different situations. They’re also quite cost-effective when compared with hiring an exterminator.

Ultrasonic Repellents

Ultrasonic for molesUtilizing technology designed to drive moles away from your home is one of the most humane and effective solutions currently on the market. With ultrasonic mole repellents, the moles that call your garden or backyard home may be on the hunt for a new place to live shortly.

Ultrasonic mole repellents work by emitting a sonic pulse, typically between the 400Hz and 1,000Hz range, into your soil where moles burrow. This pulse is unpleasant to moles, though it doesn’t hurt them, making them want to find another place to look for worms and rest other than your yard.

Most ultrasonic mole repellents cover around 500 to 700 square feet of land in your backyard, but you can easily use multiple repellents to cover a larger area. Ultrasonic mole repellents also work well when combined with other repellent options.

Ultrasonic mole repellents are one of the safest options if you have domestic pets in your backyard. Cats and dogs won’t be bothered by the ultrasonic noise and there are no harmful chemicals or poisons for them to get on their paws or in their mouth.


When it comes to DIY mole removal, mothballs are probably not the first option that came to mind. As effective as they can be for protecting your fine wool garments, they may also help you in the garden with your mole problem if used the right way.

MothballsWhy mothballs though? Because moles don’t like strong scents like this and they often send them looking for a more comfortable place to rest and find food. If you have pets, make sure they’re kept away from the mothballs and they don’t end up eating them in the process!

  • Start by locating the entrance to a trench or hole that has been dug by a mole in your yard. You may find just one or two holes or there may be a lot of them. Make sure you take the time to find every entry point that will need treating with mothballs.
  • Sprinkle a few mothballs into every entry point moles have created in your backyard or garden area. Use a small garden shovel to push the mothballs further into the hole. You can even add a little bit of soil to block the exit slightly, trapping the scent and making it effectively stronger.
  • Check for signs of life every few hours until the moles have left your area. At this point, you can use that same garden shovel to shore up the holes and keep the moles from returning once the scent has dissipated.

Repelling Granules

Mole repelling granules are a product that you’ll find in almost every hardware store and garden store. That’s because they’re cost-effective and easy to use when it comes to getting moles out of your backyard or garden.

These types of repellent granules come in a few different formulas, but in almost all cases, the main ingredient is castor oil. Like the mothballs mentioned above, castor oil is a very unpleasant scent to moles and it usually makes them scurry away from a hole or trench quite quickly.

Tomcat granules

Following the manufacturer instructions when using mole repelling granules is important, but there is a basic guideline you should follow to get the most out of these products:

  • Spread mole repelling granules over the area that needs to be treated. For larger mole infestations, this may mean a few to a dozen different areas.
  • Sprinkle a small amount (about 1/2 cup) of the mole repelling granules directly into the entrance of mole holes or trenches. This will make the process a little more effective in terms of overall coverage.
  • Using a hose or sprinkler, water the area for 15 to 20 minutes, helping the granules spread out in the area and penetrate the soil, making them more effective.
  • Repeat the process in different areas of your garden or backyard. You may need to do this a few days in a row to get the maximum effect and keep moles out of your backyard.

Unlike many options for deterring and catching moles, mole pellets generally contain a poison that is designed to get rid of moles by killing them. In some cases, these pellets may deter moles who are interested in the area when placed properly though.

Typically, mole pellets contain zinc phosphide, which will kill moles within 24 hours when used correctly. There’s also very little risk when it comes to using products that contain zinc phosphide in your garden, though pets and children should be kept away at all times.

An Eastern mole can live up to six years.

Use these basic tips when trying to take care of your mole problem with mole pellets:

  1. Identify active tunnels in your backyard or garden. Active tunnels will have a raised roof and signs of activity within the last 24 hours. Mark the areas where you find active tunnels with a garden flag or other marker.

  2. Punch a hole in the top of the active tunnel areas and add about one teaspoon of pellets per area. Close up the holes with a garden shovel to help seal in the pellets.
  3. Check the areas where you added mole pellets every 24 hours. Mole pellets that contain poison like zinc phosphide will typically remain active for a long time in dry environments. Once you water your grass or garden or it has rained outside, most lose their effectiveness within three weeks and may need to be reapplied. Keep mole pellets out of reach of domestic pets and children at all times.

How to Deter Moles

Moles aren’t the brightest enemy you’ll face in your garden, and the fact is that they can’t even see very well! That doesn’t mean that deterring moles is always an easy task. Once they’ve left your yard though, that doesn’t mean they won’t ever come back.

For many avid gardeners and homeowners, the answer isn’t always more repellents or poison though. Sometimes deterring moles from being interested in your backyard or garden is as simple as what you plant.

  • Alliums. These easy to grow bulbs attract butterflies and repel moles.
