Place a suitable bait in the trap, ideally a piece of bread toasted with bacon or a piece of bacon itself.
Mice will not disdain a nut, even if you live in a strictly vegetarian household.
Pull the folding spring mechanism to the farthest position, and while holding it with your finger, carefully rest the support pin into the recess in the bait plate. The less you insert the thorn into the groove, the more sensitively the trap will react. A properly set mousetrap should snap even with a light tap on the table. When handling a wooden trap, you do not need to use gloves; unlike rats, mice are not bothered by the human scent.
Lean the trap against the wall perpendicular to the floor. The mouse, while scurrying around, will run directly into the bait, and the snapping mechanism cannot miss.Regularly check the trap and reset it or replace the bait if necessary.
Set traps in the late afternoon or evening. The mouse is a nocturnal animal, so you increase the chances of success if you set the trap before nightfall. In the dark, you might unnecessarily disturb the mouse.
Set the trap in places where mice are likely to appear. Place them along the walls where the mice most frequently scurry. They avoid open spaces and do not like to run across them. They usually emerge through cracks in the walls and floors.
You should place traps where mice might be searching for food sources. So not under the bed, but rather in the pantry or the kitchen. A suitable place to set traps can be traced by the tracks in the dust on the floor or by mouse droppings.
