Dealing with wasps' nests requires the application of common sense by everyone involved - to decide how to do the job as quickly and safely as possible, whether on the ground floor or up in the eaves.
One the reasons we need common sense is that there are no prescriptive rules on how the job can be done. All options are open, including ladders and extendable poles.
It's the 'can do' attitude which enables common problems to be dealt with - and missions to the moon. Health and safety doesn't get in the way: the stinging criticism should be directed at the jobsworths not us!
