I hate bugs in general, but most common ones don't bother me too much. Spiders are a notable exception, though I've managed to get over my phobia of smaller ones to be able to kill them without pause. I am still irrationally terrified of big spiders, especially hairy ones.

Wasps also freak me out a bit. I'll also kill all bigger bugs (centipedes, etc), but smaller ones (moths, flies, etc.) I just ignore unless they start bugging bothering me.
