How can I overcome my disgust of roaches?

I love all living creatures... except roaches. I don't want to torture them and would prefer to find a way to give them q quick kill however I can barely look at one, let alone kill it. Having woken up in the middle of the night to find one taking a stroll on my arm has left me with a horrible phobia of them. My mom would always tell me that they are afraid of people and that kept me sane until that one night. A couple of days later I found a huge one in my bathroom. As a result, I locked the bathroom placing a towel under the door and used my next door neighbors bathroom throughout the day until my husband came home to kill it. I literally freeze whenever I see one and I get this strange numbness on the base of my neck so yeah, I have a real phobia. I have a dog so placing any sprays in areas where she can get to it is out. I keep seeing some kind of electric sonar pest repellents that you stick in a socket. Do they do anything? I spray roach repellent along the outer side of my balconies, the wall and the upper outside balcony door frames which helps as I find some creepy crawlers dead in the morning. I doubt dogs eat roaches... or at least I hope not. We live near a woody hillside and they come in from there. Any ideas, suggestions? Thank you.
