🪳 Lousy Monday Lice Fact #19: Crawl Speed
Here are the facts on how lice move on flat surfaces like the floor (vs. hair):
• Lice are built for hair, not floors. Their claw-like legs are specialized for grasping round hair shafts, not smooth surfaces.
• On hair: They can crawl at about 9 inches per minute (pretty slow already).
• On smooth surfaces (like floors, furniture, or clothing): They move much more slowly and often awkwardly, since their claws can’t grip. Some sources note they may barely move at all before becoming weak.
• Survival: Even if they end up on the floor, they generally die within 2-3 days without a blood meal and scalp warmth.
👉 So, on a floor, lice are not fast crawlers—they’re clumsy, sluggish, and unlikely to travel far enough to find another head.
