Over this last season, I have done 4 trap-outs. I have read on the forum, that generally speaking, using just the cone traps, don't usually get the queen. I am feeling pretty lucky, out of the 4 I did, all 4 ended up with queens. I'm sure it's nothing I did right, probably just dumb luck. Whatever it is, I'm happy. They were each up for a total of 6 weeks.
