Honey bee colony removal from chimney, Penrhos, Pwllheli, 3 August 2011

The colony is believed to have entered the chimney on 9 July.

The client arranged for scaffolding which was installed in the back garden of No.3 in the terrace on 2 August 2011.

Below: The bees were entering through an 'elephant's foot' cap on the pot at the southernmost end of the south east side of the stack. The flue probably connects to a disused fireplace in the bedroom of No. 2 in the terrace.

Below: before work commences, three disused flues with elephant's foot caps were covered over with plastic bags to prevent bees entering them. The bags were left in place for several days after the nest was removed.

Below: The nest was attached to the lower rim of the cap, to the sides of the pot and to a small extent to the upper end of the flue.

Below: after the combs were removed, bees still in the chimney were removed with a bee vacuum which takes the bees alive with surprisingly few casualties.

Below: a comb detached spontaneously after the cap was removed and a further comb fell during removal. Both took a considerable number of bees with them. These were taken into the bee vacuum using a long tube attachment.

Below: the elephant's foot cap was fitted with a bee-proof mesh. Before replacing, some drops of Dettol and 'Bee Go' both repellent to bees, were put in the cap.

8 August 2011

The client requested that all five remaining disused flues on this 8-flue stack have their caps insect-proofed in the manner shown above. Only a couple of dozen bees were found at the stack on returning after an absence of five days.

 

Recommendation

After any work on chimney stacks, disused flues should be bee-proofed either in the way illustrated in the photo immediately above, or by fitting a ventilated cap with a built-in insect mesh, for example C-Cap.
