Never thought we have to deal with underground squirrels in this area. We first saw it with a burrow dug up leading to underneath of our driveway. We didn't see it for three weeks and about a week now, we have been smelling something like a "dead fish smell" in the house, but couldn't figured out what it was or where it came from, until one day when the heat kicked in with the overwhelming order mixed in. We called Portland Critter Control and Tim was able to schedule me in last minute for a next day visit. Tim showed up on time, very professional and well equipped. First narrowed down and identified the area with the strongest order, then explained the process. Less than 10 minutes after he started, he spotted the dead squirrel and took care of it. The whole process took less than 20 minutes! Not only he took care of the issue for us, he also check other areas in the crawl space in helping us to prevent things like this from happening again! Not only he was professional, he also was very considerate. If I ever have to hire someone again for this type of job; I hope I don't, but Tim, Critter Control Portland would be my top choice!
