Acid fly in Sri Lanka is a growing health concern in university hostels. Students at the University of Vavuniya reported recurring skin dermatitis cases. Researchers identified the acid fly in Sri Lanka as the cause. This study tracks infestation levels, seasonal patterns, and health impacts in Vavuniya.
What Is the Acid Fly?
Researchers identified the species as Paederus fuscipes. This beetle causes skin blisters and irritation. It can also trigger fever upon contact. The insect appears only during certain months each year.
Key Findings
About 89% of students recognized the insect and its health risks. However, 11% remained unaware of the danger.
Infestations peaked in April, May, June, August, and November. Local paddy farming and harvesting activities disturb beetle habitats. This drives the insects toward human settlements.
Affected students reported skin irritation, fever, and secondary inflammation. Most recovered within 4–5 days. Some cases lasted more than a week. Severe lesions appeared on sensitive body parts.
How to Protect Yourself
Keep your surroundings clean. Remove potential breeding sites near your living area. Use environmentally friendly insect management methods.
Seal cracks, gaps, and unnecessary openings in walls, doors, and windows. This blocks beetle entry into living spaces.
Wear long sleeves and pants in high-risk areas. Use insect repellents for extra protection. Bed nets also reduce nighttime exposure effectively.
