Symptoms:

Intense itching is the main symptom. It is usually worse at the waistband, in the armpits, at the bra strap, or anywhere clothing is tighter and closer to the body.

Red bumps appear on the skin. They may become crusted or scabbed from scratching.

Areas around the waist or groin may become thickened or discolored when lice have been present for a long time.

Signs and tests:

Your doctor can usually diagnose this condition by looking at your skin and clothing.

• Full-grown lice are the size of a sesame seed, have six legs, and are tan to greyish-white.
• Nits are lice eggs. They will most often be seen in the clothing of someone with lice, most commonly around the waist and in the armpits.

Persons with body lice should also be checked for head and pubic lice.
