Here is a simple recipe that helps keep insects away from ones vegetables. No chemicals needed. Also look for more information on gardening and things in my new book coming out this spring.
1 un-peeled onion
1 un-peeled head of garlic
1 tablespoon cayenne pepper
3 pints water
1 Chop onion and garlic and combine all ingredients in a saucepan. Simmer 20 minutes.
2. Cool and store in jars in the refrigerator for 6 weeks.
3. Strain and store in jars.
To use, dilute 8 tablespoons of concentrate per gallon of water. Add 1 tablespoon of dish washing liquid. Red pepper spray is a good general insect spray and is an effective repellent against insects and animals.
