Q.Can leafhoppers affect the lawn and/or plants and are they associated with scales?
I recently had a major infestation of scales on my jasmine plant that is planted in the ground. I also have a huge population of leafhoppers all over my lawn. I was wondering if somehow they are related. I have also ordered some live beneficial nematodes to combat the leafhoppers mistakenly as I have since found out that wont help, so can I use insecticidal soap with the nematodes?

They are not directly linked together, but anytime an insect draws sap, then it will likely draw more pests. This will compound the issue.
Insecticidal soap is not a very effective treatment for infestations. This is more for seeing a single insect, or maybe a small cluster and treating them there. This will require some pesticides, whether you choose natural or organic.
