If you’re looking for a startup business, may I recommend pest removal, especially of the bat variety. We have a critter currently holed up in our spare bedroom and finding someone to not just remove it, but also inspect the attic for entry points is impossible. Of the 5 numbers I found via Google in SE Michigan, 2 don’t do bats, 1 doesn’t service our area (thanks Google), 1 didn’t answer, and 1 said they could be out “maybe next Tuesday”.
If you don’t mind flying rodents, skunks, or whatever else stalks people’s houses, there is some serious money in it and no shortage of demand apparently. Me, I have to figure out how I’m going to take out a 4 ounce bat with a tennis racket (which I have yet to procure) in a confined space slightly smaller than the space needed to swing the tennis racket.
Expect updates on broken light fixtures, broken mirrors, or a recounting of the excruciating process of getting rabies shots. Or, perhaps all of the above.
