How do I get rid of these damned cluster flies?
My roof space is full of cluster flies. They find a way into the house, gather and die at the windows. How can I get rid of them?Cleaning expert Stephanie Zia says, "Cluster flies can squeeze through the smallest of cracks, so having all window and roof seals checked and filled with sealant or quick-drying cement may work, though pest-control experts say even this might not be enough. However, once inside, they are relatively easy to eliminate with insecticides, a vacuum cleaner or special traps. The Cluster Buster (£15.95, from pestcontrolproductsonline.co.uk) is designed to attract and capture them on the windows where they gather. Their presence in the trap attracts even more flies. If using a vacuum, target inactive hibernators first, then move on to active ones. For serious swarms, contact the council."
