- A US region is seeing an unusually high number of "eye-biting" black flies that attack faces.
- The tiny insects, a type of black fly, are causing itchy, red welts on people and pets, with some residents reporting allergic reactions after prolonged exposure.
- The surge in Southern California, particularly in the San Gabriel Valley foothills, is attributed to unusually warm winter temperatures and increased river flow from early snowmelt, creating ideal breeding conditions in fast-moving water like the San Gabriel River.
- Although their bites are painful and persistent, vector control officials say the black flies do not transmit diseases.
- Authorities are implementing larval treatments in waterways, and residents are advised to use DEET-based repellent and wear light-colored, loose-fitting clothing as adult flies are expected to remain active for several weeks.
