It seems there is a yellow jacket nest close to our front porch. We couldnt eat lunch there this afternoon due to them. So I put out a homemade yellow jacket trap, and it seems to be working good, saw lots of them nearby, some already inside it. Will have to check it this evening when it gets dark. Thank you Lord for Your wisdom in dealing with this naturally without all kinds of nasty chemicals that hurt innocents creatures like honey bees and butterflies.
