Preventing mice from entering garages is crucial, as garages often provide easy access, shelter, and food sources for rodents. Even small gaps under garage doors can allow mice to squeeze inside. By installing a heavy-duty bristle strip along the base of the garage door, these gaps are effectively sealed while still allowing smooth door operation. This durable barrier blocks mice from entering, reduces the risk of nesting and damage, and adds an extra layer of long-term rodent prevention.
