Leafhoppers and Planthoppers
There are over 12,500 varieties of leafhoppers and planthoppers, that feed on the sap from plants, grass, and trees but most are harmless to the plant.

Ways to Get Rid of Leafhoppers and Planthoppers

Just leave them – By either using the Yellow Sticky Traps or looking over your plants and the amount of leafhopper and planthoppers is small, do nothing. Seldomly are they are a huge threat and there are plenty of natural enemies for them to contend with, like ladybugs and spiders.
Floating row covers – When plants are young you can install floating row covers. The ones below allow sun and rain to get through but not the insects.
Apply insecticidal soap – the thing about insecticides and leaf and planthoppers is that they would only be effective on immature insects. Adults could easily escape and just come back.
