A little to soon to leave a complete review, but as far as customer service it was excellent on all levels of contact between us and customer service, quoting and the technicians. As far as the chemical that was used to deter the wasps we have seen a few but it has been cold. The one day it was warm we saw a few wasps but not approaching the areas where they normally go, kind of just flew near areas they always go. Time will tell and I will be watching. If all goes well in the next few weeks We are totally happy with everything. Great people.
