I have spittle bugs at the base of most of my strawberries. What is safe
to
use? I have sprayed with a sharp stream of water and washed some off, but
the next day they are back or more are there. I don't want to kill the
strawberry plants. They are just starting to ripen.
I have them planted in raised beds and this is the second year in the
ground.
Thanks
