Hummelkurt,
Congratulations!!! X:X
I'm more than a bit jealous....I'm a new Beek but have had 5 swarm traps out for probably a month now and I'm still 0-For! :(
Many of experienced folks on here can offer some solid advice, but if I'm not mistaken, don't be in a hurry to take it down....give them a few days to get established.
Good Luck! :)
