Staph Infections from Bug Bites: Symptoms, Risks & Treatment

Yes, bug bites can become infected with Staphylococcus aureus (normally on skin). Scratching introduces bacteria through broken skin.

Signs of Infection

• Increasing redness, swelling, warmth, pain at bite site
• Pus or honey-colored drainage
• Red streaks spreading outward
• Fever, chills, fatigue

Treatment

• Topical antibiotics (mupirocin) for small, superficial infections
• Oral antibiotics (cephalexin, clindamycin, TMP-SMX, doxycycline) for spreading cellulitis
• Drainage if abscess forms

Prevention

• Don't scratch bites
• Clean with soap and water
• Apply OTC antibiotic ointment
• Cover with bandage
• Seek care if worsening

MRSA is possible—culture guides therapy if not improving.
