The payment is an automatic deduction. They do the spraying for critters and they come on average about once a month. The one individual, Ralph, we've known for over 20 years and the guy - aside from the fact that he's exceptionally professional - is also personable. He comes to the door, chats and has a wonderful virtue of remembering things about you and your family. He asks how our son was doing in college, etc. It had nothing to do with pest control but he humanized the service for sure. Everything they've done over the years as far as meeting our pest control needs has been exceptional. They are extremely dependable. We were bothered by some tree rats that were in our yard and they put a bait box and serviced it and it took a long time but over a span of several months we were able to get rid of the tree rats. They were successful in getting in our house, they got up into the attic area of our house and we could hear them at night. It was extremely disconcerning to my wife so on Ralph's next visit I shared this story with him, I said they must have some way of getting in the house. I looked at the places where they could get in and I gave up and couldn't find it. In about 30 seconds Ralph walked around the house and found the juncture of eaves was the point. We had to get a ladder to get up in there to see they had chewed an entrance. Ralph relocated the bait box at that entrance, they took the bait and problem solved. We waited a couple of weeks because the last thing I wanted was to seal that hole with them inside. After a couple weeks we sealed it, returned the bait box to it's original position and life's been good. There was no extra charge for all of that. It was included in our monthly service. We've been using them for 20 years.
