## Do-It-Yourself Insecticide for Vegetable Gardens
Protecting your vegetable garden from pests is essential for a bountiful harvest. While commercial insecticides can be effective, they can also be harsh on the environment and your family’s health. Here’s a guide to creating your own effective and safe DIY insecticide for your vegetable garden:
## Natural Insecticide Ingredients
The following natural ingredients have insecticidal properties and can be used to create effective homemade insecticides:
Garlic: Garlic’s pungent odor repels insects and its sulfur compounds have insecticidal effects.
Chili: Capsaicin, the compound that gives chili peppers their heat, is effective against many insects.
Peppermint oil: Peppermint oil’s strong scent repels insects and has insecticidal properties.
Diatomaceous earth: Diatomaceous earth is a fine powder made from fossilized algae that kills insects by dehydrating them.
Neem oil: Neem oil is an extract from the neem tree that has insecticidal, fungicidal, and antiviral properties.
Rubbing alcohol: Rubbing alcohol is effective against soft-bodied insects like aphids and spider mites.
Soapy water: A simple solution of water and dish soap can kill soft-bodied insects by dissolving their protective outer layer.
