About 30 years ago, the worst house guest ever arrived in honeybee hives in the United States. As a result of forcing the bees to become their literal host, the parasitic Varroa mites have passed viruses that have decimated entire colonies, contributing to the loss of 40% of the colonies in the U.S. But scientists may have found a solution to the viruses these mites are spreading. And that solution is from mushrooms!
As Bret Adee, a third-generation beekeeper stated in an interview with NPR about the mites, “Killing a bug on a bug, without killing the main bug, is really tough.” 3
So let’s take a look at how mushrooms are being used to combat the deadly viruses these mites have brought into hives!
Sometimes a catastrophe is exactly the catalyst we need to go out and learn more about the world. And on the best occasions, we learn that the best solutions don’t require a big change to our practices.
This is an innovation you can bring up whenever bees or mushrooms come into your conversation. (Which, let’s be honest, should be a lot!)
Fungus, to put it concisely, is awesome. With what’s believed to be over 5.1 million different species , we now know they connect the world through microscopic threads called mycelium and they offer a buffet of benefits—including the antibiotics you and I have to thank for protecting us against deadly bacteria.
And now, it appears they have yet another function. Fungi from genera Fomes and Ganoderma have been enlisted to create an antiviral for honeybees! 5
This short video produced by the great Louie Schwartzberg’s for bioGraphic shows us how!

What have been the impacts of this mushroom mixture?
In a great piece from WIRED, written by Robbie Gonzalez, we get a great look at how all of this works. Here’s a little snippet about the results of introducing the mycelium extracts of reishi and amadou mushrooms into hives:
“In both indoor experiments and outdoor field tests, bees that fed on mycelium extracts fared significantly better than those that drank only sugar water. In caged bees infected with DWV [Deformed Wing Virus], the researchers observed an 800-fold decrease in virus titres (a measure of the level of virus in the bee’s system) among bees dosed with amadou extract. The effect was less powerful in the field, which are less strictly controlled than lab trials—colonies fed reishi extract saw a 79-fold reduction in DWV, those fed amadou extract a 44-fold reduction—but the results were still highly significant. (In other field tests, bees fed reishi extract saw a remarkable 45,000-fold reduction in Lake Sinai virus—another disease ravaging honeybee populations.)”
