23 Plants That Repel Garden Pests

An endless struggle within the realm of gardening is keeping away bugs and insects that want to harm your precious crop.

An easy way to naturally deter these pests is by planting the right herbs, flowers, and plants that discourage them.

Many of those that will be discussed below are also great additions around your patio and outdoor furniture.

These pest repelling plants naturally help to keep off ants, mosquitoes, and others when you’re outside enjoying the weather. Below is the list of plants that deter bugs in the garden and home.

1. Basil

Basil is among the plants that repel mosquitoes or gnats and your standard house-fly. It also works on thrips, flies, and aphids.

Another perk is that it grows easily in a pot on a windowsill, so you can have some in your kitchen as well as in your garden to keep you protected both inside and out.

Basil is easily incorporated in many recipes, so you’ll never run out of ways to use your basil once you start growing it.

2. Lavender

Not only is it a gorgeous flower, but using lavender can keep insects away, particularly flies, fleas, mosquitoes, caterpillars, and moths.

Not only does it add some color to your garden or windowsill, but lavender also adds a sweet and relaxing fragrance to the home or garden.

In addition to growing it in your garden or a pot, you can also tie small bundles of the herb over doorways and near windows to keep insects out of the house.

3. Lemongrass

Lemongrass is a key ingredient in many mosquito-repelling candles and oils.

This ornamental grass grows as an annual in most locations, but it will be nice and tall and potent during peak mosquito season.

4. Mint

Mint is a great mosquito repellant herb as well as a tasty addition to many dishes.

However, it tends to grow aggressively, taking over any garden bed it may be planted in or near.

The best bet is to plant it in a container. Not only will this contain the herb where you want it, but it will also make it easier to move it to a different location (such as atop your patio table) as needed.

5. Rosemary

If your veggies are being endlessly harassed by bugs, you may want to plant some rosemary nearby.

Rosemary grows well in-ground or in a container, and is also a good choice for most ornamental landscaping.

As it grows it will hold off most bugs, but you can also use the herb to make a natural repellent spray.

Simply add some dried rosemary to boiling water for half an hour, then strain into a container that contains just as much cool water.

Store the mixture in the fridge in a spray bottle and use it when needed.

6. Bay Leaves

Bay leaves are great at keeping away flies that might otherwise lay their eggs in your garden.

Another bonus is that bay leaves are a savory addition to many soups, stews, and pasta.

7. Dill

Dill is another double-duty herb. It’s very successful against garden insects such as aphids, spider mites, cabbage loopers, tomato hornworms, and squash bugs.

To protect these specific plants, add it to your garden in the vicinity of the vulnerable items.

8. Petunias

Another common garden flower, petunias are just as productive as they are pretty. These easy-growers are great at protecting your garden from aphids.

Companion planting with petunias also helps rid your garden of tomato hornworms, asparagus beetles, leafhoppers, and squash bugs.

You can find them in almost any color you prefer, and they tend to grow very easily, whether in-ground or in a container.

9. Fennel

If you have a problem with slugs and snails attacking your garden, fennel should be planted in or around your garden. The plant also repels aphids.

10. Thyme

This herb discourages whiteflies, ants, maggots, stink bugs, corn earworms, cabbage loopers, and tomato hornworms.

It isn’t extremely aggressive (like mint) so can easily be incorporated throughout your garden to protect your cabbages and tomatoes.

11. Alliums

Plants belonging to the Allium family are great for driving away slugs, flies, aphids, and cabbage worms. Some examples of these plants include chives, leeks, and shallots.

Find the one that’s right for you and your garden, and plant it close to anything from peppers to broccoli to carrots to keep them safe from pests.

12. Chrysanthemums

These are excellent flowers to plant in your vegetable garden to control nematodes, spider mites, harlequin bugs, Japanese beetles, and even lice and fleas.

Chrysanthemums have a natural ingredient called pyrethrum which is a strong all-round insect-repellant.

These flowers add a nice pop of color anywhere you want to plant them in your yard to protect your garden from unwanted pests.

13. Marigolds

These flowers give off a scent that repels mosquitoes and aphids, and sometimes even rabbits!

They make for a beautiful border around your garden and will help protect the health of your other plants as well.

14. Nasturtiums

If your garden seems to be loved by squash bugs, beetles, or whiteflies, you’ll definitely want to companion-plant some nasturtiums.

Nasturtiums release a scent in the air that naturally keeps off many insects without harming any other plants or even the beloved bee.

15. Onions

Although they’re mostly known for turning off your date, onions are also great for getting rid of certain harmful insects.

Now, they’re not a total bug deterrent like some of the other plants, but they are great at deterring cucumber beetles and even carrot maggot flies.

Some farmers also plant onions near their tomatoes and kale to help keep aphids at bay.

16. Calamint

Yet another mint family member, calamint is great for keeping at bay cabbage worms and cabbage loopers, as well as moth larvae.

This mint cousin, however, spreads very easily like mint itself, so be careful where you plant it.

17. Garlic

Garlic protects your blueberries, roses, and raspberries from Japanese beetles, as well as from aphids on your lettuce.

It may also reject stink bugs, spider mites, ants, and caterpillars, so it’s a great companion to any plant that might be susceptible to those pests.

18. Catnip

A perennial member of the mint family, catnip doesn’t proliferate quite as much as mint does, so you’re safe to plant it directly in your garden.

It protects eggplants, radishes, and other plants that are susceptible to flea beetles.

19. Tansy

Many gardeners will plant tansy near their roses to keep away Japanese and cucumber beetles.

It’s believed that it gives off a scent that confuses the pests, making it difficult for them to find the rose bushes and make their homes there.

20. Borage

This herb works best on garden pests such as hornworms and cabbage worms.

It also makes a nice-looking addition to your garden and will support your local honey bee population.

21. Castor Oil Plant

This should first be prefaced by the warning that castor should be grown with caution — it is poisonous to humans and animals if ingested.

That being said, if you plant it with care and only where appropriate, it is excellent at getting rid of moles and voles. 

22. Tomatoes

That’s right, planting tomatoes can help protect other plants in your garden.

However, be sure to plant at least one companion plant nearby that will, in turn, protect your tomatoes from pests.

In particular, they will keep your asparagus free from pests as the scent of the plant gets rid of asparagus beetles.

Since many gardeners plan to have tomatoes anyway, it’s helpful to know that they can perform a double-duty.

23. Citronella Plant

The scent citronella is obtained from the Cymbopogon nardus plant. It is a member of the geranium family and resembles spiky ferns.

Mosquitoes hate the smell of the citronella plant. 

Simply planting it in your garden is not enough to drive them away; however, crushing or touching the leaves will release its oils.

The scent from the oil is what they hate, preventing them from coming near.

Takeaway

This is an extensive list of pest repellent plants to consider growing.

These are quite easy to cultivate. If you take the time and plan it correctly, you can have the best companions near each of your plants, dispelling most harmful insects and protecting the health of your garden.
