Get after it yourself. I know the company may technically be responsible but get some traps.
A trap won't solve anything at this point. I don't think I would have a problem catching momma, but she will eat a hole in the house to get back to her babies. If she can't get back to them, I then have dead raccoons in the ceiling. The worst part is, they're in between the first and the second floor, with no way to access them.
