How can I catch a mouse in the house without a trap using a jar at home? - briefly
Place bait (e.g., peanut butter) at the bottom of a wide‑mouthed jar and set a smooth ramp or cardboard strip that leads up to the opening, encouraging the mouse to climb in and become trapped. Then slide a thin piece of cardboard under the jar, lift it, and transport the mouse outdoors for release.
How can I catch a mouse in the house without a trap using a jar at home? - in detail
A glass or plastic jar with a smooth interior surface works best for a humane capture. Select a container that holds at least one liter of liquid; the opening should be wide enough for the mouse to enter but not so large that it can easily escape once inside.
First, prepare an attractive bait. Peanut butter, bits of cheese, or small pieces of fruit placed directly on a piece of paper towel create a strong scent that draws the rodent toward the jar. Attach the bait to the inner rim or a small stick that reaches the bottom, ensuring the mouse must step onto the bait to reach it.
Next, position the jar on a flat surface near known activity zones—behind appliances, along walls, or near droppings. To prevent the container from rolling, place a thin wedge of cardboard or a rolled towel underneath one side, creating a slight tilt that encourages the mouse to move toward the lower edge where the bait sits.
When the mouse steps onto the bait, its weight will tip the jar onto its side, causing the opening to face upward. The animal will scramble into the container to reach the food, and the jar will fall into a stable position, trapping it inside. Immediately secure the lid with a rubber band or tape to avoid accidental release.
After capture, transport the jar to an outdoor area far from the home, preferably at least 100 meters away. Open the lid slowly, allowing the mouse to exit on its own. Dispose of the bait and clean the jar with hot, soapy water to eliminate scent trails that could attract other rodents.
To increase success rates, repeat the setup in multiple locations and monitor daily. Replace bait if it loses scent strength, and ensure all entry points—cracks, gaps under doors, and vent openings—are sealed after removal to prevent future incursions.
