We have had bees coming and going to one of our chimney pots for over two years. Hence unable to light he wood burner for fear of fire. We are in Cobham Surrey. Anyone able to assist? It would be nice to be free of them and have a warmer ottage this winter!
Suggest pest control to kill bees and possibly chimney sweep to destroy nest combs. Although a lot depends on whether you have a metal flue liner, then the nest may be outside of your main woodburner exhaust.
If they can't destroy it you'll need a builder to assess the situation and may need some major structural work doing depending on exactly where the nest is in your chimney
It's incredibly difficult to remove bees from inside chimneys and this time of year you are running out of time for a re-housing job.
This was a job better tackled in the early summer.
Sorry to be so pragmatic, but you don't have many choices, other than another cold winter.
