I've discovered a bumble bee nest in my garden. It's on the top of my conservatory roof. We found a lot of dead bees and dozy bees in our washing and all day today outside (first really warm day of the year here) I could hear a constant buzzing. Investigated and they're in a bird house on our conservatory roof. It's a swarm. Coming in and out constantly and a constant noise. The bird house is full and covered in bees 
Google says they'll go after a season's up and a bee charity recommends leaving them but does concede there are people who will remove them but say it's not very ethical.
I'm quite frightened of bees and am a writer. Sitting on the patio (where I intended to write all summer...) I can hear the swarm. I know bees are endangered but I would really like them gone. AIBU?
