Home Remedies to Control Garden Pests

“The glory of gardening: hands in the dirt, head in the sun, heart with nature. To nurture a garden is to feed not just the body, but the soul.”

This famous quote by English poet Alfred Austin beautifully summarizes how gardening makes a person happy and healthy from the inside out.

Those who love gardening take care of their plants just like their children.

Among other things, you worry about slow-moving insects and other pests that can cause significant damage to your vegetable, plants, herbs and flowers.

Slugs, snails, earwigs, caterpillars, aphids, earworms, ants and mites are just some of the destructive pests that should not be allowed to roam free in your garden.

While pesticides can take care of these problem insects, they are typically not environmentally friendly and often contain harmful chemicals that you don’t want on your homegrown produce.

Fortunately, many natural remedies can help control garden pests without damaging the plants or soil.

Here are the top 10 home remedies to control garden pests.

1. Neem Oil

Neem oil is effective at saving plants infested with aphids and other harmful pests, such as mealy bugs, cabbage worms, beetles, leaf miners, ants and caterpillars.

The organic compounds in neem oil act as insect repellents and are also effective in controlling the spread of many types of fungi that infect plants.

Even the U.S. Environmental Protection Agency has found that cold-pressed neem oil is safe and does not pose a risk to people or the environment, when used according to label directions.

  • To make a foliar spray, pour 1 quart of warm water, 2 teaspoons of neem oil and 1 teaspoon of dishwashing liquid into a spray can. Spray the solution on the foliage and stems, making sure that it gets to places where insects usually hide. Spray every 3 days for at least 2 to 3 weeks.
  • Alternatively, you can use neem-based products available in the market to get rid of harmful garden pests. Follow the instructions on the label.

Always water the plants a few hours prior to spraying.

2. Diatomaceous Earth

Diatomaceous earth, made from fossilized water plants called diatoms, works as a good all-purpose insect repellent and treatment.

It can help you get rid of insects like aphids, ants, mites, earwigs, bedbugs, adult fleas, beetles, cockroaches, snails and slugs.

It is deadly to animals with exoskeletons, like most insects. The microscopic fossils have razor-sharp edges that can damage the insects’ outer shell, causing them to dehydrate and die.

  1. Fill a shaker container with diatomaceous earth.
  2. Sprinkle it on the garden bed and the surrounding area to deter pests from reaching the plants and kill those that may have already invaded.
  3. Repeat as needed.

3. Peppermint Oil

Another great way to control pests in your garden is through the use of essential oils from bioactive plants like peppermint. This herb has strong antimicrobial and pest-repelling properties.

In addition to peppermint, you can also use other essential oil like that of rosemary, thyme, eucalyptus, lavender, clove, spearmint, basil, and citronella.

4. Hot Pepper

Pepper works as a broad-spectrum, organic treatment for a number of garden pests, including aphids, lace bugs, cabbage maggots and spider mites.

According to the National Pesticide Information Center in the U.S., pepper works as a deterrent for a range of pests that eat or damage shrubs, trees and smaller plants.

Slugs and snails are attracted to beer. It’s not the alcohol but the yeast or yeast by-products that attracts them.

  1. Fill a few empty cans with beer.
  2. Bury the cans in your garden soil up to the rim.
  3. Leave them overnight so that the creepy creatures can move into the beer and drown.

  5. Repeat daily as needed until you are satisfied with the result.
