How do I get a bees / wasp nest removed?
Bee and wasp nests should only be removed by experts and it's an unfortunate fact that pest controllers usually destroy wasp nests as they are notoriously difficult to move; therefore be sure that removal is necessary.
Your local authority can supply contact details of people who could remove nests.
