During the rainy season, we often see light insects like moths, midges, and flying ants gathering near lights. These insects do not bite, but they can still carry germs like bacteria and fungi. If they land on a cut, wound, or insect bite, they can spread those germs and cause skin infections.
How Light Insects Can Cause Infection
Light insects and other rain insects may look harmless, but they can carry tiny organisms that cause infection. If they land on broken skin or a scratched insect bite, it can become an infected bug bite. If not treated, the infection might turn into cellulitis—a serious skin problem that causes redness, swelling, pain, and heat in the area.

If you already have a wound, contact with these insects can make it worse. The infection may spread quickly. It’s best to get medical help early. You can visit KBK Hospital for proper care and treatment.
Mosquitoes and Houseflies: Common Rainy Season Vectors
Apart from light insects, mosquitoes and houseflies are also very common during the rainy season.
Mosquitoes spread diseases like dengue, malaria, and chikungunya. If you scratch a mosquito bite, it can get infected and even lead to cellulitis.

Houseflies carry germs that can land on wounds or food. This can cause skin infections, stomach problems, or make healing wounds worse.

What Are Vector-Borne Diseases?
Vector-borne diseases are illnesses that spread through insects like mosquitoes, houseflies, and other rain insects. These insects carry harmful viruses or bacteria and spread them when they bite or land on your skin or food. While light insects don’t directly cause these diseases, they can still carry germs on their bodies and pass them to wounds. Staying clean, avoiding insect exposure, and getting early treatment can help prevent these infections.
Hairy Caterpillars and Blister Beetles Can Also Harm Your Skin
Some insects like hairy caterpillars and blister beetles also cause skin problems:
- Hairy caterpillars have tiny hairs that can irritate the skin and cause rashes or allergies. Scratching those areas can lead to infection.

- Blister beetles release a harmful chemical that causes painful blisters. These can become infected bug bites if left untreated.

How to Stay Safe form light insects and When to Get Help
- Wear full-sleeved clothes to avoid insect contact
- Keep wounds clean and covered
- Don’t scratch insect bites
- Use mosquito repellents and keep your home clean
- Cover food to avoid housefly contamination
If you notice signs like swelling, redness, pus, or fever, it could be a skin infection. For fast and safe treatment, contact KBK Hospital to avoid complications like cellulitis.
Conclusion
Even though light insects don’t bite, they can still spread infections during the rainy season. Combined with mosquitoes, houseflies, hairy caterpillars, and blister beetles, they increase the risk of infection—especially if you have open wounds. Stay safe, protect your skin, and get medical help early if needed.
