Adjustable Plastic Mouse Guard & Hive Entrance Reducer

Universal Beehive Entrance Control – Robbing & Rodent Protection (432mm x 50mm)

Protect your colony and control hive traffic with this Adjustable Plastic Mouse Guard Entrance Reducer, designed to fit most standard UK beehives.

Measuring 432mm x 50mm, this versatile entrance reducer allows you to manage hive access, reduce robbing behaviour, improve winter defence and deter rodents such as mice from entering your hive.

With a clever break-off design, three different entrance widths can be achieved by snapping off the side sections to suit your hive setup.

Ideal for National, Langstroth, Warre and similar hive types.

Why Use a Hive Entrance Reducer?

A full-width hive entrance leaves colonies vulnerable to:

• 🐭 Mice entering during autumn and winter

• 🐝 Robbing by stronger colonies

• 🐝 Wasp and hornet attacks

• ❄ Cold drafts and heat loss

• 🌬 Poor airflow control

By reducing and controlling the entrance opening, you:

• Strengthen colony defence

• Support weak or nuc colonies

• Improve overwintering success

• Reduce stress during nectar dearth

• Manage hive ventilation more effectively

This makes it an essential part of winter hive management and robbing prevention.

How It Works

1. Snap off the two end sections from the main runner.

2. Fix the end clips to the hive floor using screws or drawing pins.

3. Slide the reducer board between the fixed clips.

4. Adjust opening width depending on season or colony strength.

Once installed, the reducer can be slid in or removed without tools.
