Item #M311
The Mouse Guard is constructed from high quality stainless steel and is designed for a 10 frame hive. Place the mouse guard in the entrance of your hive in order to prevent unwanted mice from entering the hive. The 3/8" holes are the right size for worker bees to enter and exit the hive and will keep the mice out. This is great to implement during your winter preparations and will also assist in good ventilation throughout the winter.
