My daughter was stung one night by a scorpian while in the house. The little bugger blended in perfectly with our carpet and was not easily seen, but I was able to find it and make sure it wouldnt sing anyone again. Needless to say, I went into freak out mode and called around. Blue Sky came up in my internet search and I explained what happened and they were very understanding and rearranged some things and were able to come out the same day. They explained what they did and how it keeps the scorpians away, they provided me with a one time option or a every other month service, which I opted to do. I have not seen a scorpian since, in addition, there are no spiders or other little buggers. I get calls the day before they are scheuled to come out. They also have a no scorpian guarantee - luckily I haven't had to take advantage of that.
