GLUE is not effective most of the time as it depends on the size of the rat.
RAT POISON is not recomended specially if you have children at home.
MOUSE TRAP is the only option which will work to some extent but make sure you dont leave any food lying outside when u place a trap as the rat will always go for what is easy.
