I don't like birds flapping around me but since that doesn't often happen it doesn't present a real problem ...but ... spiders!!!! I simply cannot deal with them sensibly. The last one that appeared when my husband wasn't home I sucked up the hoover as I usually do - and two days later in the transparent dust trap at the top of the stick vacuum cleaner, there the spider was, running merrily and healthily around. And he was a big boy too!! Urgghhhh!
