Snakes, cockroaches, deep sea fish - angler fish, and hatchet fish are pretty gross. And queen termites make me feel nauseous just looking at pictures of them.
I'm absolotely terrified of wasps. I break into a cold sweat if I know there's one in the house somewhere, but funnily enough I'm really fond of bumble bees. When my daughter was very small she liked stroking their little furry bodies with her finger, when they were inside flower-heads in the garden.
And spiders don't bother me in the least - can pick them up no problem.
