Outdoor Plants That Repel Ants

There are many species of ants all over the world and they can be a real pain to deal with in your home, yard or garden. Even though they feed on fleas, caterpillars, and termites, they also provide a hideaway for destructive insects that harm plants and infest our homes. For some people, sprays and chemicals come in handy in the fight against ants and are readily available. However, in these days of heightened awareness of the environment and the increased desire to use organic and eco-friendly substances, more people are shying away from the use of these chemicals. So, how can you combat the menace of ants in your home or garden? It is as simple as planting some herbs and shrubs!

We are going to give you a list of outdoor plants that can help keep ants away, but please note that this is in no way an exhaustive list.

Rosemary

Both gardeners and homemakers understand the importance of rosemary not only to spice up their cooking but also to repel ants. All that is required is to buy flowerpots, plant the herb, and place those pots around your patio or porch. You can also plant rosemary in your flowerbeds or borders.

Mint

Most of us enjoy a refreshing cup of mint tea from time to time without knowing that this refreshing plant can also act as an ant deterrent. Mint starts out slowly when planted but grows quite aggressively after the first year. You can either grow mint from seed or by removing a small piece from an existing plant, making sure to remove the piece with the root intact. Mint seeds sprout around twenty days after planting. To prevent your garden from being overrun by mint, plant it in a pot or container and bury the pot the ground. This will curtail its growth and keep it from spreading. This plant has an overwhelming scent that repels ants and can grow tall and wide enough to provide ample coverage. This makes it perfect for planting near doors and underneath windows.

Lavender

Even though it is loved by humans and very useful to them, ants detest lavender because of its oils and very pungent scent. Lavender is a versatile plant because it works not only as an aromatic ingredient in any potpourri mix, but also works well as an indoor fly repellent.

Thyme

Who would have thought that the thyme that lends aromatic goodness to salad dressing and other culinary delights would also help to repel ants? But yes, it does! This herb loves the sun and grows slowly, thriving in cracks as well as along sidewalks or flowerbeds. Once grown, it will keep spreading perennially. Even though it does not smell as strongly as other plants that repel ants, it works equally well.

Tansy

Also known as golden buttons because of its little clusters of aromatic yellow blossoms, tansy blooms in the summer. This plant is a wide spreading herb that does not die once it takes root. It grows in a clump and can grow as tall as four feet (1.2 meters) tall and about one and a half feet (0.45 meters) wide. It is also self-seeding and multiplies by spreading its roots underground. Since it spreads fast and wide, you can control it by cutting it back before it flowers or by simply pulling it out by hand.

Caution!

Wear gloves before touching tansy to avoid any toxins being absorbed into your skin.

It has antifungal and antibacterial properties which made it useful for lining coffins in the past. Nowadays, the leaves and dried flowers are used in floral bouquets.

Common Yarrow

Common Yarrow, also known as soldier’s woundwort or milfoil, is a shrub-like plant which grows perennially. It can grow up to ten inches (25.4 centimeters) tall and sixteen inches (40.6 centimeters) wide with either shade or full exposure to the sun. It is quite effective in repelling ants and can be planted from seed or from a cutting taken from an already established plant. It blooms between June and September and its flower and leaves can be harvested for floral arrangements. It is also purported to have medicinal properties and can be used to treat wounds.

Pennyroyal

Pennyroyal is a relative of mint and can be quite invasive, so if you plant it in your garden, without proper care, it could overrun it. It is, however, an effective ant repellent with a sweet aroma and supple purple flowers. If you want to use pennyroyal as a companion plant for those that are prone to pest invasion, one tip is to plant it in a container before burying it in the ground. This will curtail its spread while also protecting the other plant. Pennyroyal is a versatile plant with an aesthetic value that will make whatever effort you put into cultivating and curtailing it worth your time.

Garlic

Garlic can trace its origins to Central Asia and is available in over 600 varieties. It is a perennial plant that grows well in well-drained soil with exposure to sunlight. It is arguably one of the plants that is most used for ant deterrent or pest control purposes. Folklore suggests that garlic can scare away unwanted guests such as vampires, evil spirits, and ants. While we cannot provide any proof of its efficacy in dealing with evil spirits or vampires, it has been proven to be an effective ant deterrent. When you plant garlic around doorways and beneath windows, it ensures that you will not be disturbed by any pesky, irritating ants. Garlic is also an excellent addition to your culinary repertoire with proven medicinal value. So, plant this versatile bulb around your kitchen doorway or garden borders and you will not regret it!

Marigolds

A number of ornamental plants have been discovered to act as ant deterrents and marigolds are one of them. One advantage of marigolds is that it is a plant that does not spread fast, so they will not overrun your garden while protecting it. Marigolds are annuals, so you will have to replant them every year. This could be either an advantage or a disadvantage depending on how you look at it as well as how this works for you and your garden.

There is also no need to expose your household to harmful chemicals. By simply planting these aesthetically-pleasing herbs and ornamental plants around your home, you will not only be protected from ants but will also have delicious homegrown herbs readily available to cook with.
