How are headlice created ??Or where do they come from -if they can only live on human heads ??

Their legs are specially designed to hold onto human head hair, they lay eggs (nits) that hatch in two weeks, they can be spread to anything your head touches (your hands, pillows, hats, other people, or even in your carpet).

It's impossible to identify the worm from that description.  There are a number of options.\n\nHowever, my best guess is that it is a horsehair worm.  Horsehair worms are rather fascinating creatures, possibly responsible for inspiring the film "Alien".  Adult worms live in water where they lay their eggs.  The eggs hatch into larvae, who make their way to an appropriate place to be eaten!  Once an insect (usually a grasshopper or a relative, such as cockroaches) eats them, they crawl out of it's digestive system and live in it's abdomen, growing every larger.  When they become adults, they secrete a chemical, causing the insect to get very thirsty.  It rushes to the nearest body of water, where the horsehair worm tears it's way out of the insects stomach and into the water, where it looks for another horsehair worm so it can start the whole process over again.

OK. these things are insects- so they can be killed.\n\nFirst of all, face the problem. If you have head lice, they are also probably in all your apartment, also clothes, hats, etc. Also anyone you are in close contact with.\n\nFor the hair- it is easy. Simplest solution is to shave all hair. I do mean ALL hair, because lice lay eggs on any hair (including eyelashes, armpit hair, pubic hair) they get across (they look like silvery streaks and are almost impossible to get rid off by conventional means)\n\nIt also means you have to boil all your bedclothes, clothes, caps, etc. and spray all over the flat (including the walls and behind/above/under the bed) with some good bug killer- preferably the kind for crawling insects (longer lasting). I hope you're not allergic.\n\nIf you don't want to shave all hair, cut it as short as possible then soak in vinegar for a couple of hours at least (covered in a towel) then comb out with a special comb- very close set teeth (some pharmacies may have them). You have to repeat it at least once a week for 3-4 weeks. This is because new lice hatch from eggs every 2 weeks or so, so you have to kill them before they have a chance to lay new eggs.\n\nFor mature insects it is easy enough- rub oil or butter on your hair, leave it on for 3-4 hours. Blocks the bugs breathing holes and they die. Not quickly, but they die eventually.\n\nHot iron treatment may suffice- both for clothing and for hair. Not as effective as shaving, but worth a try.\n\nRemember you got the bugs from somewhere- so you're likelly to get them again from the same source\n\nIn any case, they are alive and therefore they can be killed- just "stay the course". A bit like fighting the Taliban- some say hopeless- but if you persevere long enough they quit living

yes...  they come from filth and are contagious...  they are mites that get under the skin....

Sure they can!  \n\nYou wouldn't believe how many tiny critters live on (and in) all of the living things that we can see...\n\nFor example; In, and on, your body there are TRILLIONS of little guys that call you home. The same is basically true for all living things (plants included), and some of these guys are clearly parasitic, though luckily, most are helpful, and many are even necessary for our survival. That's right; we need them, but they don't need us!\n\nMy favorite "Wow" tidbit I give my students: There are more cells of OTHER critters within (and on) you than there are cells OF you... by a factor of 10!

There are indeed parasites that can invade the brain, there is another one called the loa loa worm that is called the eye worm. I have a book with a picture of a work being pulled right out of this guys eye. Anyway is will blind you. And for the parasites in the brain, if someone did get this it is fatal. The good news is you have to go to some really third world countries to get these things.

This is a common misconception.\n\nNails, hair etc do NOT continue to grow after death - it is merely the illusion of your skin contracting around the follicles etc that makes it appear so.

I'm always so puzzled at how ignorant americans can be. Evolution doesn't say we evolved from apes. The skulls aren't fake and haven't disappeared. The world didn't start in 6000 BC. Get some culture, people! And, dear Asker, that's what you get from asking this in the Religion section. It should be in Science, you'd get better results.

Some are full of maggots that they are going to land and lay soon. Some may be of a different fly species that are naturally larger. I believe that 'housefly' covers a several different kinds. And there is probably a bell-shaped curve that covers their sizes, like a lot of other things.

I haven't actually met any life forms face to face, but there certainly seems to be some extremely strange beings registered with YAHOO!ANSWERS. Some of the questions posted just defy answering or reading - the English language obviously provides many of the alien 'life' forms, already on our planet and with Internet access, with a problem, they have difficulty forming intelligible phrases. I do, however, admire their persistence and efforts to communicate. Keep up the good work and hope to see you soon down the pub for a pint.

Go to your local pharmacy or drugstore.  You can purchase a product called "RID". Its a shampoo that kills headlice.  Once you've shampooed, you'll take the small comb, that comes with the shampoo to comb the hair to remove dead lice or possible eggs that may be attatched.  Very important to stip bed of sheets and pillow cases and wash in hot water as soon as possible, too.   Good luck!  (Rid is sold over the counter, btw..so don't be embarrassed.)

If it has no visible head (except darker mandibles) and no legs, it is a fly larva, most likely Brachycera, the most common sub order of flies (house flies, blow flies, etc.). It is difficult to determine the exact species, or even family for that matter without seeing it under a scope with a key. It is most likely some species of flesh fly or blow fly, their larvae tend to be very mobile, althought they typically dont travel very far, so the source of your maggot problem may be or possibly was not too long ago, just outside the area where they are coming in by. If they depleted their food resource, typically rotting flesh or dung, they will sometimescrawl away in search of more food....\n\nhope this helps!

Don't amphibeous species grow back different limbs?  Besides, I heard they IMPORT their frogs legs from a wide variety of Nations, or at least they could if they ran out (it's not as if they are restricted from free trade, and isolated from the rest of the world).  But logic tells me the bodies would just remain the same, but you would have to do a little research, or actual testing, to find the true answer to your question.   But it is my opinion that my answer is simple enough to make sense to you.

im not surprised if it exists. but those will probably not be sunhuman, but bacteria instead. did you know that most things ARE covered with some form of bacteria? But of course most of it isnt harmful as well. as long as the surface has the right conditions, the bacteria can live on it.

humans are born with hair. it may be miniscule, or ridiculously fine, but its definitely there. by hair, we don't just mean on the top of the head, hair can be anywhere on the body, including the fine hairs on your arms and stuff.\nthe most hairless mammal i can think of is a whale; they only have hair on their lips.

Good grief, you need some basic understanding of human anatomy: without a blood supply nothing can live outside the human body. When organs are transplanted they are held suspended on ice in coolers in solutions made to mimic body fluids.  Kidneys cannot live outside the human body and must be connected to a blood supply to function.\n\n A fish breathes water through its gills and cannot live on land unless it is amphibian, in which case it is not a fish. A fish is nothing remotely resembling a human kidney.\n\nhttp://en.wikipedia.org/wiki/Amphibian

I can't find any definitive sources, but apparently they were created by Aborigine bush hands trying to keep the flies out of their eyes when they worked.  The "whitefellas" thought this right clever, and started to do the same thing.
