Wow. I just used your advice... actually I put a piece of yellow paper in a plastic sheet protector and then sprayed it with PAM cooking spray.I went inside to put the PAM away, came back out not more than 5 minutes later, and there were 6 or 8 teeny tiny black flying critters stuck in the oil. If these are pests, I am delighted, but is there any chance they are pollinators?
