natural bug spray Brew a pot of coffee and let it cool. Pour into spray bottle and spray on plants. It freaks out the bugs and gives your plants (if they are the type that need it) a tiny shot of nitrogen.
sprays all the plants citrus juice and garlic. The citrus kills off aphids, while the garlic repels slugs, and discourages any aphids from crawling back again. Here’s how to make it: Ingredients 2 large lemons 3 cloves of garlic 1 tablespoon of crushed chillis 1.2 litres of boiling water
Gallon of water, 1 chopped onion add to gal of water. let it sit under the sun for 3days and spray it over your veg plants, n flowers to keep bugs from eating the leaves. I personally used it on the lawn and around the windows n doors to keep the bugs n mosquitoes away and it worked. I read this in magazine from old sturbridge village. Cant recall what year.
