John is very good and will explain things to me what he is doing and what I can do to keep the ants out. He will take the time to spray inside if I need it. He is quite thorough and I'm quite satisfied with the results.
“So what you have here is an air conditioning duct. The scorpions are not going to be inside the duct. Small amounts of moisture condense on the outside of your duct work, inside your wall. Little scorpions like that moisture. They end up cruising along the interior of your walls, along the exterior of your ducts. What happens is the get to an exchange like this where the air is leaving and they kind of work their way around. See how this is not sealed here? This is the leading way they are coming into your actual closet. It’s usually one or two sources that they are really able to access the interior of your house. They can be in your walls, but if they can’t get out of your walls then they aren't going to hurt you. They can fit through anything the width of a credit card, or 1/16th of an inch. Let’s put as many barriers as possible between them in the yard, and the interior of your wife’s shoes.”
