Live Traps. Live traps use the rodents’ natural tendency to investigate and wiggle into holes. In these traps, the rodent can get in but cannot get out. This is often through a wind-up mechanism triggered by touch. When the rodent goes into the hole, the mechanism snaps it to the other side of the trap where it is captured. These traps must be regularly inspected and emptied. In addition, once captured, the rodent must be humanely killed or released where it won’t reenter the home or building or be of harm to others. Glueboards. Glueboards are not usually very effective in rat control, as these larger rodents can sometimes pull themselves loose from the glue or, if caught by only a foot or two, it can simply drag the board around stuck to its body.
