In a small bowl, combine the cinnamon sticks, cloves, chili flakes, and star anise. Stir to mix the ingredients evenly.
Fill the Bags
Spoon the spice mixture into the muslin or cotton bags, filling each about halfway. Tie each bag securely to prevent any spills.
Place the Bags Strategically
Place these anti-mouse bags near any potential entry points, such as doorways, vents, or small gaps. For extra protection, also put them inside cupboards, closets, or anywhere you suspect mice might enter or hide.
Refresh Every 1-2 Months
Over time, the scent of the spices may fade. Replace or refill the bags every 1-2 months to keep the scent strong and effective.
