I'll chime in.  We had AZ Exterminating do a full-out caulk of our house because we have scorpions.  My husband wonders if we were seeing more scorpions after that because they were trapped in the house when we caulked.  Needless to say we switched to Assured Pest Control when we found a record 4 scorpions alive and kicking in one night in our front foyer and living room.\n\nSince switching to Assured [(623) 877-0726], we still see scorpions outside...dead or dying.  Haven't had any in the house in some time.
