Wasps. I hate them so much. Anything that can fly into my flat without being invited and sting me when I try to get it out, let alone call it's pals over to help him out... this kind of thing is NOT COOL. >=(

Also, I have a minor fear of very large numbers of ants. A few? No problem. A full massive load of them, covering a good area so that you can't see anything beneath them but more ants? Particularly, the door knob to my house?
