A customer contacted us about a major squirrel problem in his attic in Bloomfield Hills, MI. It was obvious where the squirrels were getting in because they chewed a huge hole behind the gutter on the fascia board. Upon inspection of the home and attic we identified a black squirrels as the prime suspects. By removing the gutter and installing the one way squirrel door we were able to safely and humanely exclude the squirrels from the attic without setting traps. We will be going back this week to repair the opening and install the gutter.
