Do you dust the DE on your plants or make up a solution with water? Very interested in the DE angle as that would mean I wouldn't have to patrol for the JBs as often (although the frequent rains we've been getting would mean more application of the DE). DD's raspberries get covered in the pests. I tap mine into a bucket of water with a little dish soap (otherwise they'll swim for 24 hours or more) so I'm always out patrolling for the JBs. I've noticed that they arrived late this year and that there aren't as many of them. Most of mine fly in from other yards right into my sunny garden.
