If you’re looking for a way to control pests in your garden without using harmful chemicals, here’s a step-by-step guide on how to naturally kill pests in your garden:

Identify the pests

Identifying the pests in your garden is the first step in controlling them. Look for signs of damage, such as holes in leaves, chewed stems, or wilted plants. Also, look for the pests themselves, such as aphids, caterpillars, or snails.

Remove pests manually

One of the most effective ways to control pests in your garden is to remove them manually. This can be done by picking them off by hand or using a vacuum cleaner to suck them up. If you’re dealing with slugs or snails, set up a beer trap by filling a shallow dish with beer and placing it in the garden.

 The slugs and snails will be attracted to the beer and will drown.

Use natural repellents

There are several natural repellents that can be used to deter pests from your garden. For example, planting marigolds can help repel aphids and other pests. Garlic, onion, and hot pepper sprays can also be effective in keeping pests away. 

Mix one tablespoon of minced garlic, one tablespoon of minced onion, and one tablespoon of hot pepper flakes in a quart of water. Let it sit for 24 hours, strain, and spray on plants.

Use companion planting

Companion planting involves planting certain plants together that can help deter pests. For example, planting basil with tomatoes can help repel aphids, whiteflies, and tomato hornworms. Planting lavender near rose bushes can help repel aphids and spider mites.

Encourage natural predators

Encouraging natural predators, such as ladybugs and praying mantises, can be an effective way to control pests in your garden. You can do this by planting certain plants that attract these insects, such as yarrow, dill, and fennel.

In conclusion, there are many natural ways to control pests in your garden. By identifying the pests, removing them manually, using natural repellents, using companion planting, and encouraging natural predators, you can keep your garden healthy and pest-free without using harmful chemicals.
