Moths. Can't bear to be in a room with one. I was about to go into my office building one morning and suddenly spotted a huge hawk moth clinging to the brickwork, right by the door. Couldn't go in! I had to phone a colleague to come out and get rid of it before I could go in. Urrgghh.
Lack of public toilets in towns.
I've got another 'keen'... Ouch!
