I have a similar 'ug' feeling towards spiders. I have found two methods most effective:

1) Find a tolerant girlfriend (or partner of your chosing) willing to take care of the dirty work without judging you for standing on a stool in the corner, or (after you stop srieking) accusing her of being an inhumane murderer.

2) A trick I leaned when still in Toronto with a coakroach problem. I lived on the 13th floor and when I found one or the little bastards (on the cieling especially - argggg), I would get a bucket full of hot water and a broom stick and get him into the water to roast a bit, then throw him out the window - meanwhile yelling abusive warnings to the rest of his family that if they do not leave them and their 72,000 children will suffer the same fate. It didn't solve the problem, but it definitely made me feel better...
