I’m in rural southern Illinois, and while we have both types of bugs around here, the squash and shield bugs have done more to stop me being a squash grower than anything. There are so many shield-type bugs around here – my kale and Brussels sprouts were damaged by harlequin bugs, and I’ve seen green shield bugs on my tomatoes today. At least I have ways to control the Japanese beetles and grasshoppers – nothing seems to stop shield/squash bugs short of squishing them.
