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, they can simply drag the board around. Glueboards are generally considered less humane than other traps because they do not kill the rodent; they just keep it stuck until it starves to death or until it is dispatched by the person who set the trap (an unpleasant task, to say the least).
