We called SOS after our pediatrician recommended them to us. I, too would recommend them to anyone with a scorpion problem. We had two different exterminators out to spray but it was not cutting it. I truly think sealing is the way to go. It's been four months and we've only found one inside that was essentially trapped. This was after finding 1-2 a week. Everyone is so knowledgeable and a pleasure to work with; they treat everyone like family. Great company and effective service! Hopefully the next scorpion I see will be suspended in a glittery resin paper weight.
