Your guy, Ken, showed up right on time. After surveying the area inside and outside of the house and doing a little "dusting" for my wasp problem, he took another look around and made a good catch of finding the semi hidden location of where the wasps were congregating and beginning to make their nest, so he dusted a little more in that area. It's been 5 days and I have not seen any accumulation of wasps around the house. Thanks!
