Disease-resistant bees

This is not really a natural treatment for chalkbrood, but more a piece of advice or a proactive approach you can take. You can reduce the risk of chalkbrood by breeding and maintaining disease-resistant bees

For instance, certain bee strains (like Apis ceranaCarniolan honey bee, or the Western honey bee) show a natural resistance to pests and diseases. Again, this is not a natural treatment for chalkbrood, but something you can do to prevent it. 

And it’s not that difficult to do. Breeding for disease resistance is not a new concept.

Applied correctly, it is not only an effective natural treatment for chalkbrood by curbing the spread of the disease, but also bolsters the bees’ immune system, empowering them to naturally resist the disease.

Vitafeed Green

Another product that has gained traction in recent years is Vitafeed Green. This all-natural liquid extract blends walnut, marjoram, and thyme essential oils. But what makes it so unique?

Well, each of these oils brings its own set of benefits to the table. Walnut oil fortifies the bees’ exoskeleton, marjoram bolsters their immune system, and thyme, known for its antifungal prowess, combats chalkbrood. 

And that’s not all. Vitafeed Green goes beyond just these oils. It’s crafted to boost bee health and stimulate the growth of their colonies. A robust colony can adapt to environmental changes, like adjusting ventilation and heat, which is crucial in fending off fungi. 

Remember, fungi love damp, poorly aired places, and a weak bee colony can’t ventilate its hive effectively.

Another feather in Vitafeed Green’s cap is its ability to stabilize the pH of the bee gut, keeping it in the sweet spot between 6.3 to 6.6. This balance is a shield against harmful bacteria and fungi. 

Plus, its antioxidant properties pack a punch against both the pesky Varroa mites and the chalkbrood-causing fungi.

Whether you’re looking to kickstart colony growth in spring or prep your bees for winter, Vitafeed Green is your go-to. And the best part? A liter of this magic potion can treat up to twenty beehives. 

Just mix it with sugar syrup, and you’re good to go. Being a “green” product, it’s kind to the environment, leaves no residues, and is a pure boon for the bees.

probiotic treatment for honey bees

Organic mixtures and probiotics

Over the years, I’ve encountered several organic mixtures and probiotics that have shown promise in combating chalkbrood and enhancing the overall health of the hive.

BeeVital Chalkbrood Organic Mixture

One natural treatment for chalkbrood that has truly impressed me is the Beevital Chalkbrood Organic Mixture

This organic blend is meticulously crafted to inhibit the growth of the chalkbrood fungus. Not only does it contain natural ingredients renowned for their antifungal and immune-boosting properties, but it also actively helps the bees eliminate the affected brood. 

This encourages our buzzing friends to remove the mummified larvae, a clear sign of chalkbrood.

The beauty of BeeVital lies not just in its effectiveness against chalkbrood but also in its user-friendly application. 

You can introduce this treatment during spring and autumn, or really, whenever you notice signs of an outbreak. And the best part? It doesn’t taint or damage the honey during the flow. 

Simply apply 20ml-30ml of the mixture directly from the bottle between the infected brood frames. For optimal results, it’s recommended to repeat the treatment two to three times at intervals of 7-10 days.

Moreover, BeeVital works best when used with a ventilated floor and roof, ensuring that humidity, a common culprit in fungal growth, is kept at bay. 

And remember, while BeeVital is a fantastic tool in the fight against chalkbrood, good beekeeping practices are essential. Regularly cleaning and washing your equipment can further enhance the effectiveness of this organic mixture.

Strengthening hives with beneficial bacteria

Another avenue that has shown significant promise is the introduction of beneficial bacteria to the hive. Just like humans, bees have a gut microbiome that plays a crucial role in their health. 

Introducing probiotics, or beneficial bacteria, can enhance this microbiome, making the bees more resilient to diseases like chalkbrood.

These probiotics in bees work by outcompeting harmful bacteria and fungi, ensuring a balanced gut environment. Additionally, they aid in the digestion of food, ensuring that the bees get all the essential nutrients they need.

The brainy folks at the University of Canberra, especially Dr. Murali Nayudu, have been diving deep into this. They’ve been on a detective mission since 2018, trying to figure out how these probiotics can shield bees from chalkbrood. And the news is promising!

As you may know, chalkbrood, caused by the fungus Ascosphaera apis, can wreak havoc on hives, severely affecting honey production and making colonies more vulnerable to other diseases and pests.

However, Dr. Nayudu discovered that healthy bees have a bustling city of good bacteria in their guts. And when bees get sick with chalkbrood, this city gets a bit quiet. But with the right probiotics, we can bring the buzz back!

The next step? Giving the bees a special sugar drink mixed with these probiotics. It’s like a bee smoothie that can help them bounce back from chalkbrood in just a few weeks! Plus, it keeps them energetic, which is super important for keeping their homes clean and safe.

Dr. Nayudu’s current focus is on isolating bacteria capable of eliminating the chalkbrood fungus. His aim is to cultivate a unique probiotic strain dedicated to bee health.

Natural methods to ensure optimal pH in bee health

The gut pH plays a pivotal role in determining the health of bees. A balanced pH in the bee gut ensures that the beneficial bacteria thrive while keeping harmful pathogens at bay. These beneficial bacteria aid in digestion, help in nutrient absorption, and boost the bees’ immune system.

An imbalance in the gut pH can lead to a host of problems. It can make the bees more susceptible to diseases, reduce their lifespan, and even affect honey production. 

Ensuring the proper pH levels in the bee gut is not as daunting as it might seem. In its infinite wisdom, nature provides us with several tools to achieve this balance.

  1. Natural feed: One of the simplest ways to maintain gut pH is by providing bees with natural feed. Avoiding artificial or processed feeds can go a long way in ensuring a balanced gut environment.
  2. Herbal supplements: Certain herbs, when introduced to the hive, can help in balancing the gut pH. These herbs not only provide essential nutrients but also have properties that promote a healthy gut environment. One excellent option I would recommend here is the HIVE ALIVE Bee Food Supplement. If you are on a budget, Hive Alive Fondant Bee Food Supplement can also work really well.
  3. Probiotics: As discussed earlier, introducing beneficial bacteria can be a game-changer. These bacteria not only aid in digestion but also help in maintaining the right pH levels.
  4. Regular monitoring: Monitoring the hive’s health can provide insights into any pH imbalances. Early detection and treatment can prevent potential catastrophes down the line.
