I hate killing anything, but I needed to start killing squash bugs and their babies, or I wouldn't have any cucumbers this year. Now they're on my winter squash. Anyhow.......I discovered a good way of finding them (besides actually seeing them out in the open). I noticed that many of the dead, dried leaves have adults and youngins' inside them. So I just pull off the dead leaves and squish the leaves. Or I cut the leaves off into a waiting bucket of water and soap. I don't use chemicals, so this seems like a fairly useful way of killing them. (And then I apologize to them. )
