Rats are SUPER smart, so you will probably need to bait but not set the traps for at least a few days to convince them that the traps are okay. Then bait and set all of your traps.
And I would have a half dozen traps or more, not just the two. If you have more than one rat (and when do rodents ever come singly? :no:) you’re going to need more traps. The goal is to catch ALL of them that night you finally set the baited traps, because if the rats see another rat getting trapped, they will become wary and you have to go back to feeding them off the traps for a few days again.
Good luck!
