Most people think that caterpillars can’t cause too much damage in a garden. After all, they’re cute and fuzzy, and turn in to beautiful butterflies and moths—how bad could they be?

It turns out that caterpillars are very hungry eaters and can quickly damage or totally destroy many of your plants. If you think you have a caterpillar problem, follow these natural solutions to getting rid of the cute critters.

Soap and Water

An easy remedy to a caterpillar problem is a little soap and water mixture. Completely dissolve a small amount of soap in warm water, and then spray on the affected plants.

The mixture won’t harm your plants but will create a slippery surface that deters caterpillars from walking on or eating your plants.

Neem Oil

Neem oil is a natural pesticide that will keep caterpillars away but should be used with a light hand as it can harm beneficial bugs.

Dilute a small amount of neem oil (2 ounces or less) in one gallon of water, then apply with a light hand to the affected plants in the evening.

Pepper and Garlic Mixture

This potent mixture will work well for caterpillars as well as worms and aphids.

Simply combine 1 tablespoon of dried red pepper flakes, 1 whole minced onion, and 1 teaspoon of soap, then mix into a full gallon of water.

Blend thoroughly, and then let the mixture stand for at least 24 hours. Then spray wherever needed to keep caterpillars and their friends off of your plants.

Chili Spray

A home-made chili spray is another natural option for getting rid of caterpillars.

Combine 3 ½ ounces of dried, ground chilies with ½ gallon of boiling water for five minutes; remove from heat, then add ½ gallon of cold water and 2-3 drops of liquid soap.

Stir well, and let the mixture sit and cool for a few hours. Try the mixture on a small section of your affected plant(s), then check in after 24 hours.

If there are no adverse effects to the plant, then use the spray all over the plant(s) as needed.

Create a Habitat Friendly to Birds

In case you’ve forgotten your basics about birds, they like to eat caterpillars and other crawly things.

Install a birdhouse and/or some bird feed near the afflicted plants, and the birds will help significantly reduce the caterpillar population.

Word of warning: this is not the best idea if the caterpillars are affecting your fruit trees, as it will likely entice more birds to eat the fruit off your trees.

A very friendly bird to keep near your garden or other plants would be chickens. If you have the space for your own, let them wander throughout your yard and garden, and they’ll take care of the caterpillars.

Use Burlap

This is a strategy for trees that are afflicted by caterpillar invasions.

Wrap the tree trunk with some burlap (it doesn’t need to be completely covered), and the caterpillars will crawl under the “shade” during the heat of the day.

Once they’re all under the burlap covering, you can squash them, or move them by hand.

Cover Your Plants

You can use a thin mesh covering to cover all of your plants to keep caterpillars and other larger bugs off of them.

Laying down ground cover can also prevent moths and butterflies from laying their eggs in or around your plants, which can prevent a caterpillar problem from ever arising.

Complement Your Plants

Certain types of plants will naturally repel caterpillars, and can easily be incorporated into your garden or flower bed to keep caterpillars away.

Peppermint, lavender, mugwort, and sage are the most potent plants that will repel caterpillars. Not to mention, these plants smell great, are easy to maintain, and can quickly be incorporated into many of your dishes.

Remove them By Hand

An easy way to get rid of your caterpillar problem is to simply remove them all by hand and either dispose of them or place them elsewhere in your yard.

They are unlikely to return back to the affected plant, as long as you move them far enough away.

Other Methods

  • Spraying them with enough water to drown them can also be an easy fix.
  • Look for caterpillar eggs and dispose of them immediately.
  • Also make sure that you don’t have any sort of lights on in your garden or flower bed in the night, as this will attract moths, which may then lay their eggs in the area.

If left alone, caterpillars can cause a lot of damage to your plants, even laying eggs for their future generations to continue the trend. Be sure to check your plants regularly so that you can treat any caterpillar (or other pests) infestation as soon as possible.
