Vinegar, baking soda and essential oils are versatile, eco-friendly ingredients that can be used to natural pest control in your garden. These household items can be combined into effective sprays and traps to manage common garden invaders like aphids, slugs and spider mites without harsh chemicals.
As a horticulturist with a passion for sustainable gardening, I’m excited to share some of my favorite natural pest control methods using simple, inexpensive ingredients you likely have at home. Protecting your garden doesn’t have to mean resorting to harsh pesticides – let’s explore how you can harness the power of nature to keep pests at bay.
Vinegar-Based Pest Control
Aphid Spray
- Mix 1 part white vinegar to 3 parts water in a spray bottle
- Spray directly on aphids and infested plant areas
- The acetic acid in vinegar acts as a natural insecticide

Slug and Snail Repellent
- Create a barrier of vinegar around plants susceptible to slug/snail damage
- The acidic vinegar deters these pests from crossing the barrier
- Reapply after rain or heavy watering

Baking Soda for Pest Management
Powdery Mildew Treatment
- Mix 1 tablespoon of baking soda per 1 cup of water
- Spray affected plants to inhibit the growth of powdery mildew
- The alkaline properties of baking soda disrupt the fungus

Essential Oils for Pest Control
Spider Mite Spray
- Mix 10-15 drops of peppermint or rosemary oil per 1 cup of water

Homemade Pest Traps
Fruit Fly Trap

For detailed instructions on making a fruit fly trap, check out this guide from the University of Nebraska-Lincoln Extension.
Slug and Snail Trap
- Bury a shallow container filled with beer or a yeast-sugar solution
- The fermented aroma lures slugs and snails, who then drown
