Typical swarm locations
Swarm collectors in Runcorn are called most often to the older sandstone and brick properties in the old town below the bluff, to the garden trees and fascia boards of the new-town estates on the hill, to the hawthorn hedgerows along the Mersey Valley paths, and to the riverside scrub and bramble below the Silver Jubilee Bridge. The chemical-works brownfield land on Astmoor and Weston Point attracts colonies from April.
