So there have been a few around recently. Lots infact. I noticed the fuckers flying in and out of the roof, crawling under tiles. Inspecting in my loft space there's a small area I can only get to by wrigging down a four foot passage that's about 2 to 3 feet by 2 feet. At the end of this there's a chamber about four feet high by eight feet long by six feet deep. Sure enough there's a wasp nest there about the size of one and a half footballs. I've managed to spray it with wasp killing foam, twice, this evening. Everytime I spray a few wasps take umbrage and fly towards me. I exit banging arms and my head as I try to squeeze through gaps far too small for fast movement in. About to have another go. All a bit bloody scary really.
