Buy them chocolates and flowers. Give them honey. Keep them sweet. You may not be able to get them out without hiring scaffolding/ removing bricks and that will cost you a bomb. Tell them to light the fire and burn something that really smokes like damp grass. Put out a bait hive. Pray.
Thanks Poly Hive. I've suggested that. Good to know it was the right advice. They went in yesterday. Hopefully a fire will encourage them to move on...
Funny thing was I thought both my hives had already swarmed. Of course they may not be my bees, but the neighbour is very close to where I keep them.
I was called to a swarm in a chimney last year. I got there a few hours after they arrived. Some thick smoke from my smoker got them out of the chimney and onto the side of it.
On the subject of smoke, fire and bee swarms, take a look at this image. This was taken on Sunday morning, the cars had been set alight about 3am, in the apex of the roof there is a swarm of bees, the smoke and flame didn't bother them at all!
Thanks Jimmbee. I'm in Newcastle-u-Lyme - so not that near you I'm afraid - and the house is an old Victorian one. Very high! The neighbour is being wonderful and we're frantically smoking them. Though they don't seem that bothered.
Seems they're definitely my bees. They saw them rise out of my garden! Think I might be in for a bit of expense here!
Get a good fire going first and build up some heat, then get it smoking with corrugated cardboard or other paper products. Worked for me in a neighbour's chimney last year. Only prob might be that an old chimney might have leaks into a roof space that the bees could exploit to nest in the roof.
