Published in Lice Appearance 1 min read

Lice are typically grayish white or tan in color.

Lice Color Details

The color of lice can vary depending on their life stage and whether they've recently fed:

  • Adult Lice and Nymphs: Adult lice and nymphs (baby lice) are generally grayish white or tan.
  • Blood-Filled Abdomen: If you look closely at an adult louse, you might see its abdomen filled with red human blood, which can affect its overall perceived color.
  • Lice Eggs (Nits): Lice eggs, known as nits, are tiny and appear as yellow, tan, or brown dots before they hatch.

Summary of Lice Colors

Stage Color Notes
Adult Lice Grayish white/Tan May appear reddish if recently fed due to blood in their abdomen
Nymphs Grayish white/Tan Baby lice, same color as adults
Nits Yellow, Tan, Brown Lice eggs attached to hair shafts

Therefore, while lice can appear reddish after feeding, their primary colors are grayish white or tan.
