Bees nest removal from a chimney

Bees nests are currently the biggest problem as a pest in the UK and throughout the county of Cheshire. So far i have been called out to over 30 bees nests in the last 9 days, some are easily removed by calling out the beekeeping assocication and some have to be destroyed. Bees are protected unless they are causing problems to the household, therefore have to removed. If the nest cannot be removed by the Bee Keeping association, maybe inside a cavity then a pest controller will need to destroyed by the use of insecticides. This nest probably held around 5,000 - 7,000 bees and were colonised deep inside a chimney flue and took some serious dislodging.
