I am a new customer, my father recommended you. The tech came out to the house and was here about 20 min I only seen him in the back yard walking around with a back pack sprayer. When I reviewed the ticket . It said he was here for much longer which was not the case. And also it stated he applied 3-4 different chemicals he only walked around the house once. Maybe all the chemicals are in one tank. If I am wrong please let me know .
