If it wasn't for my daughter, I never would have thought of dryer sheets either. It's easy to blame the detergent, when it may be something as simple as changing from dryer sheets, to liquid fabric softener.
By the way, I do use the dryer sheets at work and at our cottage to 'try' to keep the mice away - the more fragrance, the better. I think it helps, and is certainly safer than the mothballs we used to use! ~Jan
