27 Solutions to Get Rid of Bugs on Plants Naturally

Whether you’re a professional farmer or a backyard gardener, you will come across harmful garden bugs, which can destroy your hard work seemingly overnight.

However, there are many solutions available for getting rid of bugs and plant pests organically. These range from natural store-bought pesticides to even things you probably already have in your home.

Below are some of the best home remedies and organic methods to stop pesky insects from eating your plants.

Here’s how to get rid of plant bugs naturally.

1. Beneficial Insects

While many bugs fall under the pest category, some are helpers — repelling or feeding on the pests you want to get rid of.

As a result, keeping a supply of ladybugs, spiders, praying mantises, dragonflies, hoverflies, and other beneficial garden insects around will reduce damage to your garden and help ensure healthy crops.

Besides, you can also buy most of these insects.

2. Companion Planting

Much like the helpful insects mentioned above, companion planting is an organic method of deterring pests.

Companion planting isn’t just limited to flowers either — you can plant vegetables and herbs such as onions and sage. Moreover, the seeds for many of these vegetables, herbs, and plants are very affordable.

3. Diatomaceous Earth

Diatomaceous earth is great for insect control. When the powder gets inside the exoskeleton of bugs, it sucks the moisture out of them.

Liberally sprinkle the DE around your plants for an effective killing shield against any potential pest problem. Moreover, it’s safe for humans to handle, but must be reapplied after a rainstorm.

4. Organic Liquid Soap 

Dilute soap with water to make a homemade bug spray for your plants. The solution also creates an effective shield against a wide variety of pests.

Combine five tablespoons of organic liquid soap in a gallon of water for an instant soapy water spray solution.

However, keep an eye on your leaves for any burns, signaling you to dilute the mixture even further.

5. Neem Oil

Neem oil is a superb natural insect repellent for plants.

Mix 4 teaspoons of it with 2 teaspoons of liquid soap in a gallon of water and spray the insecticidal solution on plants.

Now watch the insects run for cover as their hormones are thrown completely out of whack.

Traps

There are many kinds of traps for garden insects, some of which don’t harm them at all.

6. Sticky Trap

Using sticky traps is an effective way to control flies and pesky insects. You can also make a DIY trap of any yellow or blue paper that’s covered in a sticky substance.

7. Grapefruit Halves

Your morning breakfast can become your daily shield against insects.

Once you’ve eaten the fruit, use the rind as bait to attract snails and slugs and watch them slowly march nearby. Get rid of them as they appear.

You can also cut a grapefruit in half and scoop out the inside. Once that’s done, place the empty shell near affected plants in the late afternoon.

Slugs and snails will crawl right in to take cover. Finally, scoop them out the next norming and squish them or feed them to the birds.

8. Beer Container

To prevent snails and slugs from noshing on your plants, set out a little dish of beer to attract them.

The slimy little guys like the stuff.

The smell coming from the dish will lure them in and drown them. Afterward, scoop them out and dispose of them.

Essential Oils for Pest Control

There are some essential oils that are effective at repelling garden pests.

The basic application is 10-15 drops of oil to a cup of water. You will then place the solution into a spray bottle and apply it to the affected areas.

However, be careful when using, as some oils can also repel insects that are useful to a garden.

9. Peppermint

This one is famous for its pleasant aroma and its ability to keep out certain critters such as the mealybug [1], beetles, flies, rodents, caterpillars, and ants.

10. Chrysanthemum 

Easier to use than it is to say, this flower contains pyrethrin, which is a natural bug killer.

Chrysanthemum oil is especially useful against aphids, fleas, and ants. It kills them.

11. Pine 

Pine oil is highly effective against mosquitoes [2]. Mosquitoes find the smell utterly repulsive; therefore, they will avoid your house and garden when the oil is diffused.

12. Tea Tree 

Great against mosquitoes and ants, you can make a simple solution of tea tree oil and water and apply it with a sprayer.

Apart from those two, stinging insects and bugs also seem to hate it.

13. Thyme 

This extremely distinctive smell is not only good for controlling sucking insects, but it’s also effective against fungi, bacteria, and viruses.

14. Lavender 

Flying insects seem to hate lavender oil. What’s more, you can use it to relieve itches from bug bites.

15. Lemongrass

Lemongrass oil is an excellent repellent for fruit flies, mosquitoes, and fleas. This also makes it handy to have around the house.

16. Orange 

Orange oil is a wonderful repellent against ants, spiders, cockroaches, mites, termites, flies, and even wasps.

17. Cinnamon 

This is an effective oil for use in the garden and around the home.

Cinnamon oil makes a great deterrent for aphids (greenflies), earwigs, silverfish, mealybugs, scale insects, and mosquito larvae.

It also works great for bed bugs.

18. Basil 

Basil oil not only repels caterpillars, but also flies, weevils, and moths. Moreover, you can burn the oil and let the smoke permeate your garden.

19. Mugwort 

Mugwort oil is a strong toxicant against the Red flour beetle [3].

Household Items

There are many items that you may already have in your house that can be extremely effective at either killing or driving away pests.

Items such as hot peppers, eggshells, or even just plain soap and water — are effective at removing infestations.

20. Garlic

Garlic’s strong smell will help to keep away moles, gophers, and voles. Place the cloves in their tunnels. However, be sure to replace them periodically. 

You can also make an organic spray to use on other insects by blending 2 bulbs in a cup of water. Strain before using this natural insecticide.

21. Egg Shells

Eggshells are great for your garden soil because they not only supply calcium but also discourage slugs and snails.

The sharp edges of the crushed shells will painfully scrape their gooey bodies.

22. Pepper Spray

Not the canister, however, you can use normal pepper to make a solution that will repel caterpillars, spider mites, mayflies, and maggots.

For the recipe, puree 5 hot peppers in 2 cups of water. Next, add a teaspoon of liquid soap. Finally, strain and use this insecticidal spray on insects.

23. Coffee Grounds

Coffee makes a great natural insecticide for plants. You love it, but bugs and most animals hate the stuff.

Consequently, place coffee grounds in areas where there are bugs in the garden soil and rodents are a problem.

It also keeps away ants. Plus, it’s a great way to recycle your used coffee grounds.

Physical Action

This is an effective measure against bad insects that require little to no money at all.

If you see a plant with a minor infestation, you might be able to pick off the pests or remove a section of it without having to uproot or destroy the entire plant.

24. Pull Out Weak Plants

By pulling out weak plants that are likely to get infected and maintaining healthy soil, your garden will be much less appealing to pests.

If you do pull up an infected — or even suspected-infected plant, be sure to wash your hands. Also, disinfect the tools so that possible diseases don’t spread the next time you use them.

25. Barriers

Nets, fences, and anything that puts a strong defense between your crops and whatever wants to munch on them.

You can even use floating row covers, which block invaders but still allow sunshine in. 

26. Handpicking

Go through your garden and manually pluck off anything you don’t want on your plants — egg sacs, adults, and larvae.

27. Water Pressure Sprays

Use a water hose pressure to wash pests off of your plants. However, ensure the plants are resilient enough to withstand the pressure.

A powerful blast of water can dislodge anything that may be eating your crops — aphids, mites, weevils, bugs, etc.

Other Ways to Get Rid of Pests Naturally

  • The best way to get rid of the critters is never to have them in the first place.
  • Make your garden less desirable for them to live within by keeping it clean.
  • Avoid planting the same crop over and over in the same bed. This will  help decrease soil-dwelling pests.
  • Build up your soil. Healthy soil produces healthy plants which are better able to withstand pest attacks.
  • There are also flowers you can use to control pests. Growing these plants on the edge of your garden helps keep certain critters away.

While there are many different methods of ridding your garden of destructive insects, this list highlights quite a few organic and eco-friendly options.

Above all, with these remedies, you should be able to work towards a pest-free garden while feeling happy about the methods used.

    • Bernice, please identify before you nullify! Many beneficial insects look like bad guys. Take clear photos, or get a sample and ask a Master Gardener or local Agriculture Department to identify. Then, if it is a pest, use least toxic methods.
