Yes. Often times the pheromone left behind by rodents that have already visited the trap will help draw other rodents to it. Be sure to add fresh bait to help lure the rodents in. If you have a rat that has managed to set off the trap but did not get caught (very rare with the Trapper T-Rex Rat Trap) you may want to disguise the trap a bit to avoid a rat that is trap shy. You can simply place the trap inside of a shoebox with holes cut on either end to allow the rat to enter. This will look different to the rat and the rat will usually not avoid the trap inside.
