Are horsefly bites acidic or alkaline?

Horsefly bites are not classified as acidic or alkaline; rather, they cause a localized reaction in the body. When a horsefly bites, it injects saliva that contains anticoagulants, leading to swelling, pain, and itching. The body's immune response to this saliva can result in inflammation, but the bite itself does not have a specific pH level.
