All the Things You Didn’t Know Bees Do for Us

Humans rely on bees probably the most out of all insects in the world, but not just for honey or pollination. No, they’re actually also working away in labs and even giving us parts of their very home to help humans out. 

So if all you know about bees is that they flit from flower to flower, think again. Here are some of the fascinating ways bees have helped humans even more than just making all the flowers and food bloom across the world.

The Humble Honeybee and Medicine

The sweet taste of honey is almost certainly the first thing you think of when you think of bees. But honey isn’t just food. Medical grade honey, taken from honeybees, has been developed to help treat burn wounds. It has antibacterial properties that prevent infection, and its use has proven to be effective against a type of bacteria that are resistant to up to 13 types of antibiotics. On top of that, even honey used in large amounts didn’t make the bacteria more likely to become resistant to its antibacterial properties. 

Though research is ongoing to fully understand medical grade honey’s capabilities for treating wounds, researchers are also exploring other ways bees can help us, including with their venom 

It might sound counterintuitive. Isn’t venom-anything bad for you? Well, apparently not.

In 2020 researchers found that honeybee and bumblebee venom killed cancer cells in triple-negative breast cancer, an invasive, fast-spreading, and hard-to-treat cancer. And it killed the cancer cells without harming healthy cells. 

Dr. Ciara Duffy, who headed the study, also tested a small component of honeybee venom called melittin that can be produced synthetically and found it had many of the same anti-cancer effects.

We found both honeybee venom and melittin significantly, selectively and rapidly reduced the viability of triple-negative breast cancer and HER2-enriched breast cancer cells.

Synthetically-produced melittin means we can protect the honeybee population. It also means scientists can make it more effective as a cancer cell-killing agent by adding new components to better recognize and target cancer cells. Duffy’s team has also started testing melittin on ovarian cancer cells, which has also proven effective.

None of Your Beeswax! …Well Maybe Just a Little

It’s common knowledge that bees pollinate plants, which lets those plants produce food for us to eat. But, how much do they actually help us?

Oh, just about 30% of the world’s dietary supply. Which means every three meals a day a human eats, an entire meal can be attributed to the hard work of bees.

While other insects and animals do contribute to pollination as well, bees as a species are pulling the most weight. But it’s not just the domesticated bees living in stacks of bee boxes on the sides of fields doing this work. Studies have shown that having wild bees and honeybees interact increases the pollination efficiency of honey bees, specifically in a sunflower field. The best way to ensure that interaction is having natural habitat nearby farms so wild bees can live nearby, while still pollinating crops.

But beyond helping our food grow, and making honey from it, bees also create beeswax. It’s the substance the bees use to actually make their hives and the cells that they store honey and larvae in. For bees it serves as the building block of their home, but it also has several properties that make it useful for cosmetic purposes. 

Products like lipstick and cream use beeswax as a stiffener, which keeps the product adhered to the face better. But it also has antiseptic properties that protect the skin. It creates a thin film on the surface of skin and protects it from bacteria. This makes beeswax a good natural ingredient in cosmetic products. 

Bee Brainpower

Worker honeybees live for 15 to 38 days in the summer, and they have a lot of flowers to visit and paths to memorize in that barely two month lifespan. A bee’s brain is smaller than one cubic millimeter—a sesame seed is two to four millimeters—so researchers at Virginia Tech wanted to analyze how bees were able to keep so much knowledge in that tiny brain of theirs.

Professors Read Montague and Brian Smith put bees in a laboratory and tested how different scents, which would be flowers in the real world, sent specific signals in the bees brain as they tried to learn about a new environment. Some of the brain chemicals bees have are the same in humans, and can lead to new discoveries about how brain chemicals play into learning or brain disorders.

These are evolutionarily very, very old systems that we still have in our brains. Your can condition the bee on stimuli in the world that are relevant in a person.

Dr. Read Montague, professor with the Fralin Biomedical Research Institute at VTC

They’re continuing to study how chemicals like dopamine, serotonin, tyramine, and octopamine release in a bee’s brain to help them learn and possibly apply those findings to better understand how human brains learn as well. 

Busy, Busy Bees

Bees do a lot for us, even if we don’t always see it. The yellow-striped flyers have contributed to the ecosystem for generations, happily buzzing away while people collect their honey and beeswax, and now are studying every part of them to further medicine and research. But not everything about honeybees is always peachy.

Though they’re not endangered, honeybee populations have been on the decline. Exact numbers are hard to pin down, considering there are wild hives out there we don’t know about, but 2025 started with 2.63 million colonies in the U.S. and ended with an estimated loss of 50% of hives. Fortunately, they seem to be recovering this year, but it’s important to do all we can to support honeybee populations. 

One way to help bees is to make our system of agriculture more sustainable. Habitat loss contributes to wild bees population decline, so the less new farmland we have to make from their habitats, the more they can thrive both in human-kept hives and the wild. Learn how you can support sustainable practices like regenerative agriculture and keep habitats safe from further development.
