What should you do if a mouse is in the bed? - briefly
First, switch off the lights, approach the rodent calmly, and capture it with a humane trap or a cup and cardboard, then release it outdoors away from the house. Afterwards, launder the bedding in hot water and inspect the bedroom for gaps or holes to seal.
What should you do if a mouse is in the bed? - in detail
If a rodent appears in your sleeping space, act quickly to protect yourself and eliminate the intruder. First, remain calm and avoid sudden movements that could provoke a bite. Turn on the lights to increase visibility and reduce the animal’s sense of danger.
Next, secure the area. Shut the bedroom door and close any adjacent doors to prevent the mouse from escaping into other rooms. If possible, place a sturdy object—such as a box or a piece of furniture—between the mouse and the bed to create a barrier.
Proceed with removal. Wear thick gloves to protect your hands. Use a humane trap, a snap trap, or a bucket method: position a container against the wall, coax the mouse with a small amount of food (peanut butter works well), and slide a piece of cardboard underneath to slide the animal into the trap. Once captured, release the mouse far from the residence or dispose of it according to local regulations.
After the animal is gone, sanitize the bedding and surrounding surfaces. Wash sheets, pillowcases, and blankets in hot water (minimum 60 °C). Vacuum the mattress and floor to collect droppings, urine, and any shredded material. Apply an appropriate disinfectant to the mattress cover and nightstand.
Finally, implement preventive measures. Seal entry points by inspecting walls, baseboards, and windows for gaps; use steel wool or caulk to close openings. Store food in airtight containers and keep crumbs cleared from the floor. Reduce clutter that could serve as nesting material. Consider placing snap traps or electronic deterrents along walls to monitor future activity.
By following these steps—containment, safe removal, thorough cleaning, and structural sealing—you minimize health risks and discourage repeat incursions.
