We use Massey for pest control, including termite control and inspection, lawn treatment, tree and shrub treatment, and irrigation maintenance, and always have. They are dependable, friendly, and come right out if I give them a call. I have no complaints.
Are they too expensive? I don't know. I'm willing to pay for dependability and competence. I'm sure Dean's and Fertigator are fine too, but I'm operating on the "if it ain't broke theory."
