Typical swarm locations
Collectors cover swarms in the terraced streets of Blackwood High Street and the hillside roads above, in the allotment and garden plots on the valley slopes, along the Sirhowy River corridor and Cwm Sirhowy Country Park, in the bramble and elder scrub on former spoil heaps west of the town, and in the chimney eaves of the older terraces towards Pontllanfraith.
