For that mission impossible. If you intend to be or have been in this business for any length of time, there will be a time when, in the spring of the year, you encounter a female raccoon that has had young in your client's attic. YOu have caught the female and located the young, but they are in a spot in the house that will require you to rent a buildozer to tear down the house to retrieve those young! This is not a feasible option! In these cases the only option is to relase the female and try to harass her to move the young, either to a more accessible location that you can retrieve them or out of the dwelling completely. Don't waste your time on radio's and moth balls. About one ounce of this product will make the female remove her family from the dwelling in no more that 48 hours. It almost always workds on the first night but has not taken over two days yet. You must enter the attic to apply this liquid. Place the liquid on a tennis ball, then screw the ball to a large nylon piece of rope. Toss the ball in those hard to reach places near the den and retrieve. Do this in every spot of the attic except near the exit hole. In two days mark the hole to make sure there is no activity. Then seal up the hole.
