We would not recommend spraying your child's backpack with any product. Children are in direct contact with their backpack for a long period everyday, and they would be coming into contact with any insecticide sprayed onto the back for a long period too. It would be better to just use a heat treatment on the backpack. You can put the backpack into the dryer on medium or high heat for about an hour to kill any insect or insect egg that may be present.
