Sevin will work on that. Two applications and mine are gone completely. I keep checking once a week at least.
Did Sevin, an insecticial soap and a 3 in 1 spray but nothing slowed them down. Yes, put it out in the early morning during their breakfast time and late in the day. Gave up on pinching them to death because they were too quick. Had to pull up all the squashes. The bugs then ran to the lettuces, greens, broccoli and kohlrabi and started on the jalapenos but thankfully it got too hot for them so they disappeared. Evil nasty things. Had them last year but not this bad.
