Roof rats and Norway rats
Rodent Control in Irving
The School IPM program at Texas A&M reports that rats are wary of anything new, so traps should sit unset for several days, then be placed along runways with the trigger side against a wall and left about a week. It also advises sealing every opening larger than 1/4 inch in foundations, walls, fascia and roofs, since roof rats typically enter from overhanging trees or power lines.
