Will paint thinner kill bed bugs?

Paint thinner is a flammable liquid. Using it to kill bedbugs is more likely to burn down your house. There are sprays made for bedbugs. Bedding can be washed, and dried at high temperatures (heat kills them on bedding). If you do not have a dryer, after drying bedding on the clothesline, place it in a black plastic bag, leave bag in the sun for a day.
