Because the lice would drown on there fur underwater .
you can buy special shampoo at the pharmacy in New Zealand but it takes quite a long time. I mean i got them when i was 3 and i still have them. the maximum time takes about ten years or more (but that's only if you hardly really do anything to them) but if not then about 5-6 years.
it takes 1-2 WEEKS for lice egg(s) to hatch
Yes, my cousin's daughter's friend's sister died from it. Also, it is the leading cause of parasite death in Guatemala
No. No way for lice to enter the amniotic sac, and if they did, they would drown. An unborn baby is surrounded by liquid.
Yes, they can drown. The reason why they don't drown easily is because they form air bubbles on the side of their body, like an underwater air pocket, and they also know how to swim well. I've looked at them under the microscope, and actually if you get rid of their air bubble, they die instantly.
No. Like many insects, head lice can survive submerged in water for 8 hours or more.
The relationship is parasitic, as the lice takes blood, but returns no benefit to the human host.
It actually takes very little water to drown, only a tablespoon or so.
You should wait about a week to make sure the lice are gone.
First, try and see if it is poisonous, snakes get rid of lots of pests and are mostly good. Drowning takes a LONG time and is not recommended. If you must, hit it in the head with a shovel, it is much more humane.
Pubic lice infestation has no long-term effects.
