Mr. Khan (from Pesticon) is extremely knowledgeable, thorough, and professional. He started the visit by asking me to tell him all the necessary information about what I had observed regarding my new mouse problem. Then he systematically inspected each of the areas where I had noticed activity/noise, and set bait stations in those areas. He set additional bait stations in a few other areas that are common mouse problems, even though I had not noticed activity there, just to be thorough. Next, he went outside to inspect any possible entry points, and was able to figure out which of those points were giving the critter(s) access. Mr. Khan sealed all possible exterior gaps around pipes, etc. I also asked him to take a look in my attic, even though I had not heard any sounds coming from the ceiling, and he discovered what looked to be mouse activity from the past, showing me photos he took; just in case, he distributed poison in the attic. Mr. Khan gave me detailed instructions about what to look for in the coming weeks and months so that I know how to track progress. He also told me what to be cautious of regarding my dog, in order to protect her from finding a dead mouse that had ingested poison. Overall, I found the service provided by Mr. Khan to be very professional and pleasant, and I was very impressed with his level of expertise. And Pesticon as a company provided prompt attention to my request for help, with good communication from the office staff before and after Mr. Khan's visit. They charge a very reasonable price and guarantee their work. Highly recommend.
