So I got sucked into another extraction which is most likely above my skill level but no on in my bee club is stepping up to help.
Homeowner has an oak tree that goes thru their back porch and a screech owl family lives in it via a small hole (they are small birds). It got swarmed big time. My friend from a wildlife rehab center went with me and we put a camera with the video going on a string down the hole followed by a small flashlight and took video...no owls. We are hoping they left when the scout bees started and the babies were big enough. Either that or we missed them but two many days have gone by, no way would they be alive by now.
Next step is to try to extract with the homeowner's cooperation so I built another Hogan type trap and will string it up there tonight. I'm hoping I learned from my last one enough...details I didn't think (know about) before, like keeping the tunnel dark so they head toward the light, yes they do chew thru paper; make sure the homeowners really will cooperate and not just give lip service. I'm making the husband put the box up; It entails climbing a ladder and we are already on a porch on a hillside.
So wish me luck, if we can't get it up and attached I'll have to try the funnel at the entrance without a box and then plug the hole in a few weeks. Homeowners showed me two other feral hives on their land in other oak trees...they are open to swarm traps and starting their own hive.
Here is a picture of the tree I'm dealing with.
