Neem oil insecticide against garden pests

Essential oils are often used in different homemade pest deterrents. You can easily find neem oil extract for sale, as it is largely used by gardeners thanks to its insect-deterring effect and the fact that it can prevent powdery mildew on plants. In ancient Chinese medicine, neem oil was used to treat fungus infections, which some practitioners still use. In gardening, it is used against many vermin like aphids, mealybugs, whiteflies and others.

The main perk of neem oil bug spray for plants is that it is completely safe to use on fruits and veggies. Neem oil is an essential fatty acid; it is safe for us and our pets and doesn’t leave any residue in the soil. However, you should be careful with the oil, as it can harm some plants. Test-spray on a small area and wait 24 hours before spraying the entire plant. Spray in the evening, and don’t treat the plants more than twice a week.

Here is how to mix up your own homemade neem oil spray.
