J.F. Oakes markets the Pro-Pest Ready To Use (R.T.U.) Silverfish Trap with food attractant, which is considered to be safe for humans and pets. Its smart design makes trapping silverfish and other insects and larvae that damage books, library and museum collections a snap: Just remove the food attractant from its packaging, open the trap and place the food attractant in the center of the trap bottom. Place the trap on smooth surface, and replace as needed.
