Just to update this I went ahead and called TruGreen the day I made the first post (5/24). They said they would be out in 7-10 days.
I had to call them on Friday to ask why they hadn't come out yet. They apologized and "set me up an appointment" for Tuesday 6/21.
So we'll see. If they are no-shows tomorrow I'll be getting my money back. But, before I get too hissy, I should probably ask if anyone knows if they'll come out if it rains? Seems rather silly to me to show up and try and spray stuff in the rain, but what do I know?
