The Victor Electronic M240 Rat Trap uses four "C" batteries to power an electrical trapping system that senses a rat's entry into the trap and then electrocutes it. Although the trap kills in a relatively clean way, the rat may expel a small amount of waste or blood during the process. As rats can carry diseases, you should check the trap after every kill and clean away any materials on the plates to prevent the spread of disease.
Put on a pair of gloves and a mask.
Turn off your Victor M240 Electronic Rat Trap.
Take a trashcan and the trap outside – unless you already have both outside. Hold the trap over the trashcan, turn the trap over and dump the rat into the can.
Remove the four "C" batteries.
Dampen a lint-free cloth with hot water and then wipe the plates with the cloth to remove any expelled waste or blood. Throw away the cloth. If necessary, use additional damp cloths until you've cleaned the plates completely.
Set the trap aside outside to dry for at least an hour.
Reinstall the batteries after the trap has dried. Apply a small amount of a nut butter as bait to the inside back of the trap via one of the holes.
Return the trap to its original location or move it to another area where you've seen rats. Turn on the trap.
