I'd give 4.5 but only have the option of 4 or 5. The only reason not a full 5 stars is because it took a while to hear back from them when I requested a call-back as I could still hear mice in our attic. this could be in part because of the holidays so I'm not overly fussed about it. Fortunately the service includes 3 re-calls if the problem isn't solved on the first go around.
I was able to get the first appointment very quickly and the service was quick and efficient. 2nd service was more thorough as it was done in the daytime and therefore the technician could review the exterior of the home for access points. It was located and plugged. Additional traps were placed so hopefully that does the trick and the field mice decide to stay in the field!
Only reason why not a full 10 is I'm still hearing mice in the attic 5 days after 2nd treatment. Perhaps because their exit is now blocked and so they can't get out and will just meet their maker over the next few days. Not sure how long it normally takes mice to die after eating the poison.
Overall I'd recommend.
