Offer Your Aphids Homemade Lemonade

If the aphids on your trees and garden plants don’t respond to the old “spray ‘em off with the water hose” method, give them a little homemade lemonade. Like ants, their occasional herders, aphids abhor citric acid, which is a key ingredient in the makeup of lemons, oranges, grapefruits, and other citric fruit.

Lemon peel is especially strong, so grate a teaspoon of it and steep it in a pint of hot water overnight. Then strain it through a coffee filter or cheesecloth, add three drops of insecticidal soap (to make it stick), and put into a spray bottle. The mixture may end up smelling pleasant to you as you spray it on your plants, but it’ll send those bugs packing in no time.
