Lice Symptoms: Identification and Action Steps

Key Signs of Head Lice

• Intense itching (scalp, neck, behind ears) from louse saliva
• Visible nits: Tiny, oval, yellowish-white eggs cemented to hair shafts near scalp
• Live lice: Sesame-seed-sized, tan to grayish-white insects moving quickly
• Red bite marks/sores from scratching; risk of secondary infection

Action Steps

1. Confirm diagnosis with a healthcare provider or school nurse
2. Use FDA-approved pediculicide (permethrin, pyrethrin, ivermectin lotion) per label
3. Comb wet hair with fine-toothed nit comb daily for 2 weeks
4. Wash bedding/clothing in hot water; dry on high heat
5. Vacuum furniture/car seats; seal non-washables in plastic bags ×2 weeks
6. Treat all infested household members simultaneously

Resistance to OTC products is common; prescription options exist. "No-nit" school policies are discouraged by AAP/CDC.
