Signed up when we moved into our new home when we found a couple scorpions inside the house. Informed the pest control guy that was our main concern. They sprayed inside and outside. Found another scorpion a week and a half later, called and they said too soon to come back for one scorpion (one in the house is too many!) Another spray 1 1/2 months later and let the tech know we were finding more scorpions in the back yard. He sprayed again. Over the next 30 days found two more inside the house and 4-7 outside nightly! When the office called to let us know they were coming for our next scheduled spray, I informed them of our problem. The girl was nice but just suggested they would bring some sticky pads for the entry areas and we should spray inside the house again. The spraying was not working outside at all and sticky pads were not going to keep out all the scorpions gathering in our back yard. Went to a new company. Had to pay 60% of contract to cancel. The first night after the new company we only found one scorpion in the back yard. They had several methods they used including spraying inside the walls. Feeling much better now.
