A: Call a beekeeper! Swarms usually only hang around for a day or so (sometimes only a few hours) so you need to do it quickly. After this they leave for a more permanent home. If this happens to be in your roof, you will have a bigger problem.
Usually beekeepers are happy to collect swarms, but they will often charge a small call out fee to cover expenses.
Use the postcode locator on the swarms page to identify a swarm collector near you.
