well, called out to this one
how long have they been there, 3 days, lots of bees flying in the porch
well turned up, oh they have calmed down now and on inspection turnedout to be a colony in the floor gaining access via a small hole in the porch
3 days well the might leave with smoke
so heavy smoke.....just angry bees no movement
so fabi spray,,,,,,one minute spray...........not a sausage left the hole....so they have brood in there and the excessive bees must have been orienteering emerged bees....so not 3 days but at least 3 weeks
declined this one, not into cut outs, the entrance is in the corner of the porch
suggest a one way entrnace and retain them into a new box, but may need to relocate the entrance via a flexible tube away from porch
