Painting a beehive is a common practice among beekeepers, but it is important to consider which parts of the hive to paint. While painting the outside of the hive can provide protection from the elements and help regulate temperature, it is generally recommended to leave the inside of the hive unpainted. This is because paint can contain chemicals and VOCs that may be harmful to bees, and the smell may interfere with their pheromone signals. Additionally, bees naturally apply propolis, a varnish with antiseptic properties, to the unpainted wood, which helps maintain the health of the hive. Therefore, it is advisable to avoid painting the inside of a bee colony to create a safe and healthy environment for the bees.
| Characteristics | Values |
|---|---|
| Painting the inside of a bee colony | Not recommended |
| Reasons for not painting the inside | Paint contains chemicals that may be harmful to bees, bees prefer the natural smell of wood, painted wood cannot absorb moisture, natural antimicrobial and antifungal properties of wood are lost, bees may chew on the paint, paint may interfere with pheromone signals |
| Alternative to painting the inside | Use a protective coating or stain, use water-based coatings with low VOCs, use a natural resin/wax mixture |
| Reasons for painting the outside | Protects the hive from weather and sun damage, helps regulate temperature, hides the hive, makes different sizes of boxes easily distinguishable |

What You'll Learn
Paint fumes are harmful to bees
Painting the inside of a bee colony can be harmful to bees due to the fumes emitted by the paint. While painting hives can protect the wood from the elements, there are potential dangers to bees that should be avoided.
Firstly, paint fumes can disrupt bees' pheromone signals. Most paints, even low VOC types, contain chemicals that bees should not inhale or ingest. VOCs, or volatile organic compounds, are released as gases from paints and can cause irritation to the eyes, nose, and throat. Exposure to high concentrations of VOCs for extended periods can also lead to long-term damage to the body's systems. Therefore, it is recommended to use low-VOC or no-VOC paints and allow sufficient time for off-gassing before introducing bees to the hive.
Additionally, the smell of paint can drive bees away and interfere with their pheromone signals. Bees have evolved with the smell of wood, not paint. Unpainted wood can also absorb moisture, whereas painted wood cannot, impacting the hive's moisture control. Furthermore, wood has natural antimicrobial and antifungal properties that are lost when sealed with paint, which typically contains chemical pesticides unsuitable for bees.
To summarize, paint fumes can be harmful to bees as they can disrupt their pheromone signals, drive them away, and expose them to potentially harmful chemicals. It is essential to choose the right type of paint and ensure proper ventilation and curing time to minimize these risks.

Paint can interfere with bees' pheromones
Painting the inside of a bee colony is not recommended as it can interfere with bees' pheromones. While painting hives can protect the wood from the elements, it is best to only paint the outside and leave the inside unpainted.
Paints, even low VOC types, contain chemicals that can affect bees and their pheromones. VOCs, or volatile organic compounds, are chemicals that evaporate from paint as it dries and cures, a process known as off-gassing. These chemicals can interfere with the pheromone signals within the hive, disrupting the bees' communication. Additionally, the smell of paint, even if not harmful to the bees, may drive them away.
To prevent these issues, it is recommended to use paints with VOCs under 100, and ideally 50 or lower. Water-based paints with low VOCs are generally considered safer for bees. It is also important to allow sufficient curing time for the paint to off-gas before introducing bees to the hive. This ensures that the paint is fully dried and any potential interference with pheromones is minimised.
In nature, bees live inside unpainted hollow logs, so leaving the interior of the hive unpainted simulates their natural living conditions. Unpainted wood also provides some moisture control within the hive, which can be beneficial. By sealing the wood with paint, the natural antimicrobial and antifungal properties of the wood can be lost, and commercial fungicides added to paint may not be suitable for bees.
Overall, while painting the outside of a bee colony can provide protection and longevity, it is best to avoid painting the inside to minimise any potential interference with the bees' pheromones and natural behaviours.

Paint prevents bees from chewing the wood
Painting the inside of a bee colony is generally not recommended. While painting the hive is a good way to protect the wood from the elements, most sources advise against painting the inside where the bees live.
Bees have been observed to chew on painted surfaces, particularly entrance reducers, when they try to make a larger opening. The bees will chew on both the paint and the wood, effectively scrubbing the paint off. This behaviour has been observed in hives painted with low VOC paints, which are generally considered safer for bees.
Additionally, the smell of paint, even if not harmful, may drive bees away or interfere with pheromone signals within the hive. Unpainted wood can absorb moisture, whereas painted wood cannot. Unpainted wood also has natural antimicrobial and antifungal properties, which are lost when sealed with paint. Commercially produced fungicides are added to most paints, which are chemical pesticides not suitable for bees.
Therefore, it is recommended to leave the inside of the hive unpainted to prevent bees from chewing on the painted surfaces and to avoid potential issues with smell and moisture absorption.

Paint colour can help the hive blend in
Painting the outside of a beehive is a good way to protect the hive's wooden surfaces from the elements. However, the inside of a beehive should be left unpainted. The paint colour of the exterior of a beehive can help the hive blend into its surroundings.
In suburban areas, beekeepers often paint their hives to match the colour scheme of their house or surrounding buildings. In rural areas, beekeepers may opt for colours that blend into the foliage. For example, in warmer climates, painting hives white or another reflective colour can keep the hives cooler during the summer. In colder northern areas, darker colours can help absorb more of the sun's warmth during the winter.
Additionally, beekeepers with multiple hives arranged closely together may use different colours to help the bees identify their hive. Bees can become confused when hives are stacked closely together, and they may migrate to the outermost hives. To reduce this "drift", some beekeepers decorate the front of their hives with distinctive shapes and colours.

Paint can protect the hive from the elements
Painting the outside of a bee colony can help protect the hive from the elements and make the hive last longer. The outer surfaces of hives are exposed to the sun, rain, temperature fluctuations, and other elements. When left unprotected, most wood will quickly begin to break down under this stress. Joints will begin to crack, wet areas will rot, and flat surfaces will warp. These problems can advance to the point where the interior of the hive may be exposed.
Paint helps protect wooden hive parts from the rain, snow, sun, and other weather elements. In hotter climates, painting hives white or another reflective color keeps the hives cooler during the warm summer months. In colder northern areas, a darker color can help absorb more of the sun's warmth during the winter. Keeping the hives warmer makes a big difference in how much honey is needed to survive through spring.
Before painting your hive, you will need to coat the hive in an exterior primer first before putting on the final coat of paint. The color of the primer is not important, but it is important to seal and protect the wood, help the final coat of paint adhere better, and help the surface paint resist moisture and mildew.
However, it is important to note that the inside of the hive where the bees live should be left unpainted. Most paints, even the low VOC types, contain all kinds of nasty things that you don’t want your bees to eat. The smell, even if not harmful to the bees, may drive them away or interfere with pheromone signals within the hive. The smell of wood is something they evolved with—the smell of paint is not. Unpainted wood can absorb moisture, whereas painted wood cannot—which is why the outside of the hive should be painted.
