What Are Some Common Diseases That Affect Bees?

Bees are an essential part of our ecosystem and their health is of utmost importance. Unfortunately, just like humans, bees can suffer from various diseases and health issues. In this article, we will be discussing the most common diseases that affect bees and what can be done to treat and prevent them.

Varroa Mite Infestations

Varroa mites are one of the most prevalent diseases affecting honeybees and can cause serious damage if not treated swiftly. Varroa mites feed on the bees and spread viruses, which can be fatal to their health.


Varroa mites are usually introduced to a hive by other bees that have been carrying them. They have an incredibly fast reproduction cycle, allowing them to quickly infest an entire colony.

Symptoms and Treatment

Infected colonies often display signs of poor health like falling populations, reduced honey production, and higher death rates. Treatment typically involves the use of specialized Varroa mite treatments like Apistan strips.

American Foulbrood Disease

American Foulbrood is a bacterial disease caused by the spore-forming bacteria called Paenibacillus larvae. It primarily affects larva and can be deadly if left untreated.

How it Spreads and How to Control It

American Foulbrood can be spread through the hive in a variety of ways. It can be spread between bees via their bodies, via contaminated combs, or through contaminated honey. To control this disease, beekeepers should regularly inspect their hives and use antibiotics to treat infected bees.


Nosema is a fungal disease that affects the gut of the bee and can cause a variety of digestive issues. It is typically spread through contaminated water or food, and can be fatal if left untreated for too long.

Symptoms and Treatment

Infected bees often show signs of poor health like slower movement, changes in their scutellum, and changes in feeding behavior. Treatment typically involves removing infected combs, feeding the bees antibiotics, or treating them with systemic insecticides.

Wax Moths and Wax Beetles

Wax moths and wax beetles are two common pests that can cause serious damage to a bee’s comb. These pests eat the wax that is used to store the honey, and can lead to the destruction of entire colonies.

How to Control Them

There are a variety of methods that can be used to control wax moths and wax beetles. One of the most effective methods is to use a trap such as the WD-40 wax moth trap, which will attract and kill the pests.

Colony Collapse Disorder

Colony collapse disorder (CCD) is a mysterious phenomenon that has affected bee populations worldwide. It is a complex issue and many factors may be contributing to its occurrence, including disease, loss of habitat, and pesticide use.

Understanding the Mysterious Phenomenon and Its Causes

The exact cause of CCD is still unknown, but it is thought to be linked to a variety of factors, including diseases, loss of habitat, and pesticide use. Beekeepers must remain vigilant in protecting their colonies against these factors in order to ensure the health of their bees.


In conclusion, bees can suffer from different illnesses and health issues, just like humans. In this article, we discussed the most common diseases that affect bees and how to control and treat them. As beekeepers and bee advocates, it is important to be aware of these illnesses and how to prevent them. Doing so will help ensure the health and longevity of our beloved honeybees.
