Bees and wasps. Big bumble bees used to scare the dickens out of me, after one chased me into the house and then bumped against the glass patio doors for a few minutes after I went in, but I'm not so afraid of them anymore. But wasps give me the major creeps.

I'm afraid of heights a little bit, not too bad. Flying in an airplane doesn't bother me, and if there is a fence between me and the height it is OK, but if I am up a ladder, I panic and freeze and have a hard time getting back down.
