Do you think you have a swarm of bees? There are lots of different insects flying around in the Summer months so the first thing to do is identify exactly what they are.
The Britsh Bee Keepers Association have a great page to help with this here
If you have established that you definitely have a honey bee swarm then enter your postcode on their web page to find your nearest swarm collector. Unfortunately we do not collect honey bee swarms or attempt removal of any insects from property.
If the BBKA are unable to help we would recommend the services of Cheshire Pest Solutions who are fellow beekeepers but can also deal with virtually any pest problem. Call Jim Lancaster on 01260281845
If you have a problem with a wasps nest then give Paul Jones of /www.thewaspnestremover.com/ a ring on: 07598447351
