I have been using dryer sheets (like BOUNCE) for quite some time. Instead of throwing them away after laundry use I have instead placed them all over the house (behing furniture, under beds, etc...) to control insect population. Over all it has been very effective. But now I am wondering about its toxicity and human health hazard since some (if not all) carry carcinogens. I am having difficulties accessing government lists of namebrand toxic products. Any comment?
