Perfect Beehive Entrance Reducer Dimensions While Making It
The entrance reducer is a very crucial part of a beehive. This keeps the colony protected. So, while making it you should maintain it’s proper dimension.
This post is going to guide you with proper beehive entrance reducer dimensions. Also, you will get helpful information on how to install and use it. This guide will be helpful to reduce beekeeping costs when getting started.
What Is A Beehive Entrance Reducer?
An entrance reducer in a beehive is placed to reduce the entrance of the hive. It is actually a barrier that contains 2 different sizes of entrances. In most cases, it is made of wood. But you will find made of metal too.
An entrance reducer having only one entrance is also available. But maximum beekeepers use the 2 entrance size one.
While making a new beehive a beekeeper must consider the perfect dimension for its entrance. Considering the right dimension an entrance reducer is made for the beehive. Then it is placed in front of the open entrance of the hive to reduce the space.
Why Should You Use A Hive Entrance Reducer?
You got familiarized with the beehive entrance reducer. Now you probably asking why should we use a hive entrance reducer.
A hive entrance reducer is mainly used to strengthen the difference of the colony. Reducing the entrance of the hive will prevent mice and other parasites from going through the hive.
This will prevent the steal of honey by parasites and bees from other colonies. Because the worker bees will be more strong to defend the small entrance against the enemy.
A large entrance means a large area needed to be guarded by the worker bees. So, the parasites have a large space to enter the hive easily. This will make the defense of the colony weak.
Also, during winter having a large entrance will lead to more extra moisture inside the hive. So, beekeepers might require to use a quilt box or moisture board during winter.
If the entrance is small, controlling moisture inside the hive will be easier for the bees. In simple words beekeepers like to use a beehive entrance reducer for 2 purposes.
- To protect the hive from predators like mice, giant lizards, etc. Thus an entrance reducer will enhance the defensiveness of the hive.
- To protect bees from excessive cold during winter.
Earwigs can also be a problem for your honey bee colony. Earwigs is small. So, using an entrance reducer won’t protect the hive from earwigs. If you see earwigs near your beehive. You must take necessary steps to get rid of earwigs from your beehive.
It is not mandatory for you to use a hive entrance reducer. If you made your beehive in such a way that the entrance is very small. You might not need an entrance reducer. It is completely up to you.
Most beekeepers use an entrance reducer to prevent swarming. Mainly for enhancing the defensiveness of the beehive. And I am also using it for the same purposes.
Thus, a beehive entrance reducer helps to keep the colony strong. A strong colony provides more opportunities to make more money from beekeeping.
What Are The Dimensions Of A Beehive Entrance Reducer?
The dimensions of a beehive entrance reducer vary depending on the structure of the hive and the type of bees you keep. Usually, the width is less than 4 inches and the length is 12 to 18 inches.
Depending on the frame size of the beehive perfect entrance reducer dimensions are given below.
| Hive Frame Size | Dimensions in inches ( L×W×H ) |
| 6 frame beehive | 12″×0.75″×0.7″ |
| 8 frame beehive | 12.2″×0.8″×0.76″ |
| 10 frame beehive | 16.5″×3.6″×1.2″ |
These dimensions are based on the ideal Langstroth hive. For the top bar hive, the frame size is not limited. So, the dimensions can be different for top bar hives.
What Should Be The Size Of The Holes In The Entrance Reducer?
I have already discussed the perfect dimensions for a beehive entrance reducer. You already know that an entrance reducer usually has 2 holes. So, what should be the size of these 2 different holes?
The ideal size for the large hole is 3 to 4.5 inches2 and for the small hole is 1 to 2 inches2. It can vary depending on the type of hive and the type of bees you have.
Well, honey bees can go through a hole size of 1/4 inch. But you should not keep the entrance hole as small as this. You should keep both hole sizes between 1 to 4.5 inches square.
How To Install & Use An Entrance Reducer In A Beehive?
When your entrance reducer is ready to use it’s time to install it in a beehive. The installation is super simple. You can install it in 3 simple steps. Whenever you are making any changes to your hive make sure to follow hive inspection rules.
- Step-1: Keep Your Bees Calm: You can use a smoker to calm and remove the bees from the entrance of the hive. Spray smoke a little bit at the opening of the hive.
- Step-2: Place The Entrance Reducer: Place the entrance reducer at the front of your hive opening mouth. Make sure the entrance mouth is in the upward direction.
Placing the entrance the hole in the upword direction have a benefit. After such orientation you will find less amount of dead bees than the down face orientation.
- Step-3: Switch The Hole When Needed: During summer you should use the large hole entrance. Because during winter a lot of bees will go outside through the hive. But during winter only a few bees will require to go outside. Also, a large opening might introduce very cold inside the hive. So, during winter you should place the small hole entrance instead of the large hole.
This is actually how I install and use an entrance reducer for my beehive. This is my favorite usage of this little stuff. You can choose whatever orientation you are interested in.
This video faces the hive entrance downward direction. But I like to use it in the upward direction.
If you do not want to switch between the openings you can place the large opening. If your region does not get too cold during winter. Then you do not have to use the small opening.
Also, if you use a moisture-controlling board then you also don’t need the small opening. You can use the large opening for the entire year.
Should The Beehive Entrance Be Top Or Bottom?
This question is asked by hundreds of beekeepers who are going to start their first apiary. Actually, both the top and bottom hive entrance has advantages and disadvantages. Considering those you can decide whether a top or bottom entrance is best for your beehive.
A comparison between the top and bottom beehive entrances is given below.
| Bottom Entrance | Top Entrance |
| The entrance is located at the bottom of the hive. | The entrance is located at the top of the hive. |
| It can easily be accessed by mice and other parasites. | It is usually hard to be accessed by mice and other parasites. |
| It provides good ventilation and temperature regulation. | The bees have to work hard to ensure proper ventilation. |
| The nurse bees can easily access the brood bees while coming from outside. | The nurse bees require more distance to travel to visit the brood nests. |
| Workers need to travel through the brood nest and other boxes to reach the honey super. | Worker bees easily can access the honey super. As the top entrance is just above the super, workers can easily store the honey on the super. |
| It is mostly used in the Langstroth hive | Mostly used in top bar hives. |
Though the top entrance has a lot of advantages over the bottom entrance, I like to use the bottom entrance for my hives.
Because using the bottom entrance makes temperature regulation easier. Also, feeding the broods and their nursing by worker bees is easier.
In the case of a top entrance, nurse bees require to travel more distances to visit the brood nest. This is why I like to use the bottom entrance instead of the top entrance.
If you use a bottom entrance then make sure to use a entrance reducer. Also, keep the hive bottom far from ground. At least, 2 to 3 feet above the ground. Mice guard can also be a good choice to enhance the security of the hive
You can go with a top entrance if you have any of the following issues.
- Too many mice around your beehive.
- Snowfall during winter.
- If you need to move your hive from one place to another.
While using a top entrance it might not be mandatory to use an entrance reducer. As it is not easily accessible by mice and other parasites. But using one will enhance the security of the hive.
If you want you can use both top and bottom entrance combinely. Having both top and bottom entrance all together will be halpful for bees during summer. They can easily access both brood nest and honey super. During winter you can close any one of the entrance to protect your bees from cold.
using two entrance might require to use mice guard, entrance reducer, and other protections. Because more entrance allows more ways for bees to access the hive. Equally more chances for predators to stole honey and broods from the hive
