Today I found the first three adult Squash Bugs in the garden.
I know they've been active for about two weeks, having found a few egg masses like the one in the picture. This evening I covered about 1/2 the curcurbit leaves and removed about a dozen. They take 10 to 14 days to hatch, so if I can cover the whole garden every 7 days it'll help control them.
I'm not sure what to do about the Remay floating row cover next year. The summer squash outgrew the cover before I could use the Blue Hubbards and others as a really good trap crop. However, I found no egg masses after inspecting 1/3rd the summer squash. They definitely preferred the Blue Hubbard & Connecticut Field Pumpkins.
Maybe I'll plant a later row of summer squash under the cover next year? Decisions...decisions...
