Beekeeping Pests and Predators:Common Pests in Beekeeping

Varroa Mites
Varroa mites are among the most significant pests in beekeeping. These tiny parasites attach themselves to bees, feeding on their bodily fluids and transmitting diseases. A severe infestation can lead to colony collapse.
Wax Moths
Wax moths lay their eggs in beehives, and their larvae feed on beeswax, causing significant damage to the hive’s structure. Regular inspections and maintaining hive hygiene can help in controlling wax moth infestations.
Nosema
Nosema is a microscopic fungus that affects the digestive system of bees. Infected bees have a shortened lifespan and may exhibit abnormal behavior. It’s essential to provide bees with a clean water source to prevent nosema.
Beekeeping Pests and Predators:Predators of Honeybees
Bears
Bears are notorious for raiding beehives in search of honey and bee larvae. Electric fences and other deterrents can be effective in keeping bears away from apiaries.
Birds
Certain bird species, such as the bee-eater, feed on bees. While they don’t typically pose a significant threat to bee colonies, it’s good to be aware of their presence.
Wasps and Hornets
Wasps and hornets are natural predators of bees. They can invade hives, kill bees, and steal honey. Beekeepers can use traps and other methods to control wasp and hornet populations near their apiaries.
Managing Pests and Predators
Effective management of pests and predators requires a combination of proactive measures, regular inspections, and timely interventions. Here are some strategies:
- Regular Hive Inspections: Conducting regular hive inspections can help in early detection of pests and diseases.
- Hive Hygiene: Keeping the hive clean and free from debris can deter many pests.
- Natural Predators: Introducing natural predators, such as beneficial insects, can help in controlling pest populations.
- Chemical Treatments: While chemical treatments can be effective, they should be used judiciously to avoid harming the bees.
Beekeeping Pests and Predators: Advanced Management Techniques

Beekeeping, a practice that dates back thousands of years, has evolved significantly with the advent of modern technology and research. However, one challenge that has remained consistent for beekeepers is the threat posed by pests and predators. In this second part of our series, we delve deeper into advanced management techniques, focusing on Integrated Pest Management (IPM) and its significance in today’s beekeeping world.
Integrated Pest Management (IPM) in Beekeeping
Integrated Pest Management, commonly referred to as IPM, is not a new concept but has gained prominence among beekeepers in recent times. IPM is a holistic approach that seeks to control pests using a combination of strategies that are safe, effective, and economical. This method ensures a sustainable level of control, minimizing the adverse effects on the environment.
History of IPM
The genesis of IPM can be traced back to the post-WWII era when synthetic insecticides were introduced in the United States. These insecticides were effective in reducing pest density rapidly. However, they also inadvertently killed natural predators, leading to a quick resurgence of the target pests. This cycle necessitated repeated applications, which sometimes also affected beneficial pollinators like honey bees.
By the 1950s, the term “integrated control” was coined, emphasizing a balanced mix of chemical and biological control. The primary goal was to use insecticides in a way that had minimal effects on the biological control complex. This approach evolved into what we now know as Integrated Pest Management.
Beekeeping IPM Principles
Beekeeping IPM revolves around eight fundamental principles:
- Acceptable Pest Levels: The focus is on control rather than eradication. It’s often impractical and costly to aim for complete elimination.
- Preventive Cultural and Regulatory Practices: Measures like the national “Honey Bee Act” of 1922 restrict the importation of live adult honey bees, reducing the risk of introducing foreign pests and diseases.
- Monitoring or Scouting Practices: Early detection and understanding of pest biology can offer non-chemical control options.
- Genetic Control: This involves the development or selection of pest-resistant bee strains.
- Mechanical Control: Tools and techniques, such as hand smashing or trapping, are used to maintain pest populations below a threshold.
- Physical Control: Methods like freezing temperatures can be used to control pests like wax moths in stored comb.
- Biological Control: Beneficial insects or pathogens can offer safe and sometimes economical pest control methods.
- Chemical Control: While synthetic pesticides play a role, the emphasis is on using them judiciously and in combination with other strategies.
Advantages and Disadvantages of Beekeeping IPM
Advantages:
- Sustainability
- Reduced chemical usage
- Extended life of chemicals
- Economic benefits in the long run
- Reduced risk of hive product contamination
- Lesser exposure to chemicals for beekeepers
Disadvantages:
- Requires more time and commitment
- Often involves multiple strategies
- Regular evaluation is necessary
IPM Economics in Beekeeping
The beekeeping industry must adopt the IPM approach to navigate the current economic challenges. With issues like acaricide-resistant mites and contaminated honey, IPM offers a sustainable solution. It minimizes chemical use in the short term and prolongs the life of specific chemicals in the long run. Beekeepers must be vigilant, adaptable, and proactive in their pest management plans to stay ahead of potential threats.

Beekeeping Pests and Predators: A Deep Dive into Specific Threats and Their Management
Beekeeping, while rewarding, presents a myriad of challenges, particularly from pests and predators that threaten the health and productivity of bee colonies. In this third installment, we will delve deeper into specific pests and predators, their impact, and advanced techniques to manage them.
Honey Bee Parasites, Pests, and Predators
Varroa Mite (Varroa destructor)
The varroa mite is often considered the most significant malady of honey bees. This external parasite feeds on the fat bodies of adult bees, prepupae, and pupae, leading to weakened bees and the spread of various viruses.
Honey Bee Tracheal Mite (Acarapis woodi)
This internal parasitic mite lives within the tracheae or breathing tubes inside the thorax of adult honey bees. They feed on the hemolymph (bee blood), weakening the bees and reducing their lifespan.
Small Hive Beetle (Aethina tumida)
Originating from Africa, the small hive beetle can cause considerable damage to bee colonies. The larvae of this beetle feed on honey, pollen, and brood, leading to fermented honey and a slimy hive.
Bee Louse (Braula coeca)
Contrary to its name, the bee louse is a wingless fly. While they do little harm, they can be found on both worker bees and queens.
Greater Wax Moth (Galleria mellonella)
The larvae of the greater wax moth can cause significant damage to beeswax combs, especially in weak or unattended hives. They feed on the wax, leaving behind a web-like mess.
Ants
While ants are generally not a significant threat, certain species can invade hives in search of food. They can be a nuisance to beekeepers, especially when they establish colonies close to the hives.
Mice
Mice can be a significant threat, especially during fall and winter. They chew through combs and frames to build nests, and their presence can deter bees from using the affected combs.
Skunks
Skunks can pose a threat as they scratch on hive entrances and consume large numbers of bees. Their nocturnal raids can weaken bee colonies, especially during spring.
Bears
Bears are a significant threat to beekeeping operations. They can destroy hives, equipment, and consume brood and honey. Once a bear discovers an apiary, it can repeatedly return, causing extensive damage.
Beekeeping Pests and Predators:Brood Diseases

American Foulbrood (Paenibacillus larvae)
This bacterial disease affects the brood and is considered the most destructive of the brood diseases. It can lead to the death of larvae and pupae, resulting in a spotty brood pattern.
European Foulbrood (Melissococcus pluton)
Another bacterial disease, European Foulbrood, affects bee larvae. It’s less severe than American Foulbrood and can be managed with proper hive hygiene.
Chalkbrood (Ascophaera apis)
This fungal disease affects bee larvae, turning them into hard, chalk-like mummies. Proper ventilation and strong colonies can help manage this disease.
Sacbrood
Caused by a virus, Sacbrood affects bee larvae. Adult bees detect and remove infected larvae, ensuring the disease doesn’t spread extensively.
Frequently Asked Questions (FAQs)
