Moles are small mammals from the Talpidae family. There are currently 42 species of moles worldwide, found in parts of every continent except Antarctica. They are adapted to a subterranean lifestyle, which comes from the words “sub” and “terra” meaning “under” and “earth or soil,” respectively. Moreover, moles live underground, and they survive on diets of insects, earthworms, snails, slugs, ants, and other insects. They are unique due to their strong musky scent and small, poorly-developed eyes. Since they live underground, they instead rely on their strong sense of touch and short, powerful forelimbs to maneuver through the dirt. If you have been experiencing unsightly mounds and molehills in your backyard, this guide will show you how to get rid of them using smells that moles hate.

These 6 scents will send moles tunneling their way right out of your yard!

Moles are most known for their intricate tunnel systems, which can extend up to 3 acres in length. Nevertheless, they are widely considered to be garden pests due to these expansive underground tunnels, which uproot garden vegetables and flowers. If you have been experiencing moles in your backyard, this guide is perfect for you. Read on to learn how to prevent these small mammals from wreaking havoc in your garden by utilizing these six smells that moles hate.

Red pepper and cayenne pepper are both smells that moles hate. Since they rely predominately on their sense of smell and touch, dousing your yard with spicy scents is a great all-natural, long-term deterrent for these yard pests. Simply pour a little cayenne pepper powder down the entrance of any mole hole that you find in your yard to implement this removal method. Plus, this poses no danger to any other animals, insects, or people that may be exposed to it.

Just like cayenne pepper, coffee also gives off a strong smell that moles hate. This makes it a fantastic repellant for gophers, moles, and other underground animals that might be infesting your yard. So, if you are tired of moles destroying your garden, try out this hack to get rid of them for good! You can simply sprinkle fresh or brewed coffee grounds throughout your garden to instantly get rid of moles in your yard. Since many people brew a cup of joe every morning, this is an economical and effective option to try out. If you notice new mole activity after the first application, repeat this process daily until the moles are officially gone. Following that, sprinkle new coffee grounds throughout your yard once every two weeks to stop them from returning.

Besides getting rid of backyard pests, coffee grounds have loads of other benefits for your lawn. They are rich in nutrients, especially nitrogen, potassium, and phosphorus. This makes them a great fertilizer for your soil. Coffee grounds can also be used to minimize weeds, kill slugs, and repel cats. To maximize its benefits, it should be spread across planting beds and gardens in a thin layer — much like mulch.

Eucalyptus or Peppermint Oil

Moles are repulsed by the potent scents of peppermint and eucalyptus essential oils. Due to their intoxicating scent, moles and gophers get uncomfortable and are inclined to move to a different area. To implement this method of removal, douse some cotton balls in either eucalyptus or peppermint oil and stick them in all mole hole entrances across your lawn. Then, cover the holes entirely with dirt. This process needs to be repeated for a few days to ensure the utmost effectiveness. Eventually, the overwhelming smell will cause all the moles in your garden to move to a different location. Alternatively, you can mix some essential oil with water and spray it liberally across the lawn. Another bonus to this method is that this repellant is a natural, non-toxic solution to repel moles and keep them off your property for good!

Castor Oil

The castor bean plant is toxic to moles, making it a great all-natural mole repellant. Rincin communis, or castor seed oil, is so potent that it can potentially even kill moles if they continuously consume it. Therefore, planting this crop in your yard dissuades moles from making their tunnels in your yard. Furthermore, castor oil is another popular tool for getting rid of moles and gophers already in the yard. This versatile oil is used for two main reasons. First, castor oil makes the soil smell very bad to these underground mammals. This will automatically keep them out of your yard. Secondly, it upsets their digestive tract if it is consumed. Their bodies are not designed to digest this type of substance, which can result in diarrhea if consumed. Because of that, castor oil is a very effective deterrent for moles and gophers in your yard.

Garlic

Garlic is another smell that moles hate. To prevent them from taking over your backyard, try crushing fresh garlic bulbs and placing them inside the entrance of any mole holes you can find. Repeat this daily until the moles are gone, and then again every couple of weeks to stop them from coming back. Another way to use garlic to get rid of moles is by crushing several cloves and mixing them with water to spray throughout your yard. Since they do not like strong scents, this is the perfect method to get rid of these pests in your garden. Alternatively, garlic plants are said to repel moles as well, although this is not yet a guaranteed solution.

Smoke

If all else fails, people use smoke to get moles to leave their intricate tunnel systems.

Moles despise the smell of smoke from quite a few different items. Because they are highly sensitive to smells, using smoke is a fairly foolproof way to get rid of these garden pests. Some materials you can burn include thyme, rosemary, or even tobacco. The smoke is used to “smoke out” the moles from their tunnels by placing them into the hole to fumigate their tunnel systems. This smell encourages moles to move on to a new area.
