I hope this helps.
Body lice
The body louse is slightly larger than the head louse but has the same general appearance. Unlike the head louse, which lives on its human host, the body louse lives in clothing (commonly in the seamed areas) and then transfers to the human host to feed. The life cycle of the head louse and the body louse are similar in character and duration. An important difference, however, is the ability of the body louse to survive for up to 30 days away from its human host.
Body-lice infestation is a prominent public-health problem in communities with large populations dealing with poverty, overcrowding, and poor personal hygiene. Reused mattresses and bed linens as well as communal beds are risk factors.
Itching is the primary symptom of body-lice infestation. Areas where seams of clothing are tightly adherent to the body are the most likely areas of involvement. Waistband lines, and axillary and bra strap regions, are examples of where excoriation (crusts, abrasions, or scabbing) from scratching is commonly noted. Red, itchy bite marks may be seen on the body.
The diagnosis of body lice involvement can be made by identifying lice or nits in clothing, bedding, or linens -- especially in the seam regions.
Bedbugs are related to lice. They hide among sheets, blankets, and in furniture and really do bite during the night when they seek a warm body for a meal. They usually leave brown or black markings on the bed linens and bite in rows, often leaving three or more linear bite marks.
Either way, I'm thinkin that you will itch some part of your body. LOL
