Protect your colony during vulnerable seasons with this Galvanised Castellated Mouse Guard, available in National (450 mm) and Langstroth (400 mm) sizes.
Designed to prevent rodents from entering the hive while still allowing safe bee access and ventilation, this durable steel mouse guard is an essential part of autumn and winter hive management.
Each guard features a castellated entrance design to control bee traffic and reduce pest intrusion. Depending on the size selected, the reverse side offers additional ventilation or alternative opening options — giving flexibility based on colony strength, airflow needs and seasonal conditions.
Ideal for defending against mice, rats, wasps, robbing behaviour and Asian hornet pressure, this metal mouse guard helps maintain hive security without restricting worker movement.
The guard can be fixed directly to the hive floor or brood body depending on your setup. Simply create a small fixing hole and secure using drawing pins or suitable fixings.
