Used as a direct contact spray, the coffee tea can be used to kill all kinds of scales, mealy bugs, aphids, white flies, and even spider mites on any plant. I have not had to use anything else in my whole nursery for 8 years. Used coffee grounds will kill mosquito larvae in the cups of bromeliads, and will repel fire ants. Just think, if people made coffee tea out of all the used coffee grounds that just Starbucks produces, there would be 25,000,000 less gallons of pesticides being used each and every day! Tom
