In brief: Few days

Bug bites are an annoying fact of outdoor life.
When the bite becomes infected (which happens rarely) you will need to go to your doctor for oral antibiotics. Warm compresses, anti-pain, and anti-itch medications will make the site feel better too. Antibiotics usually work within 72 hours, if you don't see improvement call your doctor.
