It might work well especially if you could get a motion sensor to find the bats. Light does make a difference.
I have had a problem where they come down behind the brick rather than into the actual attic
Changing the electronic rappeler to an audible sound seems to be working now but it worked for a little over a month on the bat setting
after cold weather I found a place near the soffit above the brick that they are entering so will fix it then
