Gardening is a rewarding experience, but dealing with persistent pests can be a nightmare. Fortunately, you don’t need to rely on harmful chemicals to protect your plants. Baking soda, a natural and affordable household ingredient, can effectively repel garden pests, helping you maintain a thriving vegetable patch or flower bed. In this guide, we’ll explore seven common garden pests that baking soda repels and how to use it for maximum effectiveness.
How Baking Soda Works to Repel Garden Pests
Baking soda is an alkaline compound that disrupts the bodily functions of many pests. It dehydrates soft-bodied insects, interferes with their digestion, and even repels larger critters due to its unpleasant taste and texture. By using baking soda strategically, you can create a natural barrier against pests without harming your plants or the environment.
