As humans, we often associate insects with annoyance and fear. This is why the business of pest control exists! We swat them away, spray them with pesticides, and generally view them as pests.
However, what many people don’t realize is that insects have played an important role in the medical industry, providing invaluable benefits to our health and well-being.
Here are just a few examples of how insects have made significant contributions to the medical field:

Maggots for wound healing
Maggots, the larvae of certain fly species, have been used for centuries to help heal wounds. These tiny creatures are surprisingly effective at cleaning and debriding wounds, removing dead tissue and promoting healthy tissue growth. They are now used in modern medicine to treat chronic wounds, burns, and other conditions.
Bee venom for arthritis
Bee venom has long been used in traditional medicine to treat a variety of conditions, including arthritis. Recent research has shown that bee venom contains compounds that can reduce inflammation and pain in joints, making it a promising treatment for this debilitating condition.


Silkworms for tissue engineering
Silkworms produce a strong and flexible silk that can be used to create a variety of medical products, including sutures, grafts, and tissue engineering scaffolds. The silk is biocompatible, meaning it doesn’t cause an immune response, and it can be easily shaped to fit a variety of needs.
Crickets for protein production
As the world population grows, finding sustainable sources of protein is becoming increasingly important. Crickets, and other insects, offer a viable solution to this problem. They are highly efficient at converting feed into protein and require far less land and resources than traditional livestock.


Ants for antibiotic discovery
Ants are well-known for their ability to fight off infections and diseases. Researchers are now studying ants to identify new antibiotics that could be used to treat human illnesses. Ants produce a variety of compounds that are toxic to bacteria, and these compounds could potentially be developed into new antibiotics.
Cockroaches for treating asthma
Cockroach allergens are a common trigger for asthma attacks. However, researchers have found that a protein found in cockroach brains, called “periplaneta americana” or “PA,” can actually help alleviate asthma symptoms. When the protein is purified and administered as a vaccine, it can reduce the severity of asthma attacks.


Butterflies for cancer research
Scientists have discovered that the scales on butterfly wings can be used to develop more accurate and sensitive cancer detection tests. These scales have intricate patterns that reflect light in unique ways, and researchers have been able to replicate these patterns to create highly sensitive diagnostic tools.
Mosquitoes for disease prevention
While mosquitoes are often associated with spreading diseases like malaria, scientists have found ways to use these insects to prevent disease transmission. Specifically, scientists have genetically modified mosquitoes to resist infection with diseases like malaria, dengue fever, and Zika virus. When released into the wild, these mosquitoes can mate with wild mosquitoes and pass on the resistance genes, eventually leading to a reduction in disease transmission.


Beetles for medical imaging
Some beetle species, including the jewel beetle, have shells that reflect light in intricate and colorful patterns. Researchers have been able to replicate these patterns to create high-resolution images that can be used in medical imaging. These images are particularly useful for studying the structure of bones and other hard tissues.
Insects may be small, but they have made significant contributions to the medical industry. By continuing to study and understand these creatures, scientists can develop new treatments, technologies, and diagnostic tools that could improve human health and save lives.
These are just some examples of how the natural world can provide valuable solutions to human problems. By studying and understanding these tiny creatures, we can unlock a wealth of benefits for our health and well-being.
Next time you encounter an insect, take a moment to appreciate the important role they play in our world.
