The sales rep told us that you would be able to use current wall application for inside bug control found out that you can't use home teams external wall unit..and you don't do flys either ..??? disappointed with the communications from what was said your company will do and can't do..your sales rep primary fault..your individual who actually does the spraying did a great job he was a plus for you..you got an extra star for him other wise 2 stars (communication)....selling your product..
