It is generally seen that we get to know a rodent’s presence by the droppings littered around the house or from chewed cardboard/food too. It is ideal for placing the bait/traps in places where there is increased activity such as feces/urine traces, hair, chewing marks, or from a place where their squeaking noise is audible. Always keep the baits/stations near a wall as rats/mice are not good with vision and always run near the walls or so. But ensure to place them out of reach to children and pets.
