Just bought a new house and my daughter and son-in-law gave me a one-time pest spraying as a housewarming gift. Randall was very thorough, polite and pleasant to have at my new home. He sprayed inside and out, no smell or residue. He sprays at my daughter's house quarterly and it has made the world of difference with ants and souders. My granddaughter saw ants outside at my old home and said. We need to call Randall, he will come get the bugs out.
