I am looking for recommendations for mouse control. I have deer mice in my attic (and maybe now in the crawlspace or at least in the walls). So far I'm only aware of two pest control companies that service the Methow Valley (for residential) - Harvest Valley out of Wenatchee and Mid-Valley in Omak. I'd like any feedback anyone has on working with either of them, or if you know of other companies.
If at all possible, I want to avoid using poison bait because of the effects on wildlife who may eat the poisoned mice. And I would strongly prefer a company (or maybe I need a separate recommendation here) who will work on securing any spots the mice may be getting in. I've used some of the expanding foam as a stopgap measure in a spot I know they are getting in, but they've chewed through it (I know, it needs steel wool or similar in addition to the foam - I'm just worried it's not going to end up being a simple project), but I know there may be more complex things to do to keep the mice out.
This is the first time I've ever had mice (house is well built and just 10 years old).
Thanks!
