Is I safe to spray raid in the back of a refrigerator?

My house is seriously infested with roaches, but my mom ignores the problem and refuses to call an exterminator. I don't leave my bedroom, so I bought a can of raid roach spray to kill off the nasty fucks in my room. I have a mini fridge and they're nesting in the back where the wires are. Could I spray that directly or would it mess up the wires? Could I spray a piece of paper and set it under the wires so the spray doesn't directly touch the wires but still reaches the bugs?
