Temperatures are in the 70s, the leaves are turning green, the bees are buzzing, the birds are chirping, etc,. etc., etc. I want to get an early start with yellow jacket traps and get them out when the queens start flying. I know there are experienced experts here, and I'd love to tap that knowledge. I know from reading that it takes about a week for a 2-litre soda bottle trap to "ripen" to be ready for the yellow jackets. What I'm wondering is when is it time to put them out? Seems to me if all the other bugs are flying, the yellow jackets are probably thinking about it, too.
