spiders!!!

This morning I was relaxing and playing wii while Reed took his nap when I happened to notice a spider running across the ceiling. I was just about to kill it with a shoe when I noticed a red spot on its back. I didn't waste any time in killing the little buger! I know that black widows have spots on there abdomen, but after doing some research on the internet there are several different types of black widows. I don't know if the spider I killed was one but I am not taking any chances since we have a little one in the house. I have Orkin scheduled to come out first thing tomorrow morning. I think this will be a good thing because I have seen 3 spiders in the house over the past 2 days. I know I sound like a wimp but anybody who knows me knows I absolutly hate spiders!!!
