Typical swarm locations
Collectors handle swarms along the Forth and Clyde Canal willow, elder and himalayan balsam corridor, in the Dalmuir Park mature trees and formal planting, on the rosebay willowherb and bramble of the former industrial and railway land, along the Clyde riverfront elder and gorse margins, and in chimney stacks and eave voids of the inter-war and Victorian terrace properties.
