Ick! Lice! Now What?
- Don't Panic!
- You don't need to run to the store and get a pesticide-based lice shampoo, or a lice spray
for your house or school. There are alternatives that are more effective than pesticidal
shampoos for eliminating lice. Also, spraying the physical environment will do absolutely nothing
for the head lice problem - except potentially make the children (and adults) ill. The National
Pediculosis Association and the well-known Bio-integral Resource Center (BIRC) recommend that
you do not spray the physical environment as there is no evidence that pesticide treatment
of the physical environment is effective in the treatment of head lice. 1,2
What to Do
The following are the best ways we personally found worked when we had to help an
employee who was struggling to stop a lice infestation in her household. The recommendations are
based on my research into this issue, and from talking to pharmacists and doctors that deal with
chemically injured patients who can not use pesticides. Please keep in mind that this is
not medical advice, nor is it intended to replace medical advice.
- Educate yourself - you can learn everything you need to know in a half an hour to an hour. The
best sources of information are from the National Pediculosis Association (in Newton, MA:
616-449-6487 and BIRC (in Berkeley, CA: 510-524-2567). The NPA has good basic information on
lice, and BIRC has an outstanding written document (the Fall, 1998 "Commons Sense Pest Control
Quarterly) full of excellent least toxic 'how tos' in terms of dealing with head lice.
The National Pediculosis Association (Pediculosis = head lice) also has a good web site, at
http://www.headlice.org that will give you current information on what they have
available, and on what to look for when dealing with lice.
- Clean up the infected person or child. We were able to do it without pesticides following
proven mechanical methods that help you comb the adult lice and nits out of the hair. These
methods may suffocate some of adult lice and nits (eggs) on the person's head, but you
must also comb with a lice comb.
You can use vasoline (if the individual isn't chemically sensitive to it - it's hard to get back
out of hair though!), coconut or olive oil (you can use any salad oil, but coconut or olive oil
are the best) to make it easy to comb out the lice and eggs. Saturate the hair and scalp with the
oil, leave it on for 20 to 30 minutes, and thoroughly comb the hair from the scalp outwards
with a metal lice comb to remove dead adults and all lice eggs stuck on hair (see
references at the end to order a metal lice comb if you can't find one locally). The oil
prevents the hair from tangling and also makes it very easy to comb through the hair. If
you have never done this, it is tedious - you need to do a small section of hair at at time.
The 1998 BIRC article has excellent and detailed instructions on how to do this. 1,2,3
For our employee, we found this worked, while the pesticide laden products did not work.
The head should be examined every day and combed with the metal lice comb to remove eggs ('nits')
if any are found until two weeks after the last nit/adult is gone. In one case I know of
personally, the individual used the pesticide shampoo unsuccessfully for six weeks (once a week),
and was able to get rid of all the lice and nits by using the oil/vasoline method just once,
followed by one week of diligent combing to remove nits with a metal lice comb.
Special note: absolutely avoid the prescription shampoos, which contain the pesticide
lindane. Lindane is a very toxic organochlorine pesticide. Organochlorine compounds which
have chlorine atoms attached to one or more carbon rings are called organochlorines. Pesticides
within this chemical group are usually highly toxic - examples include DDT. Non-pesticide
organochlorine compounds include substances like dioxin and PCBs. Lindane is neurotoxic,
causing grand mal seizures, and it is highly carcinogenic in laboratory tests. It also causes
aplastic anemia, as well as other blood disorders.
6,7,8,9,10,11,12,13,14,15,16,17. The NPA specifically recommends you
never use these prescription shampoos ("Kwell" is the name of one of them) as lindane can "attack
and permanently damage the central nervous system." 1
- Clean up the infested person's clothing and bedding.
- This requires washing clothing and bedding in a washing machine at a water temperature
of 120 to 130F, 20 minutes of actual agitation time. It needs that long a time of
exposure to the hot water to kill adults and eggs.
- The actual bedding (mattress and pillow etc.) should be vacuumed thoroughly daily,
as should other areas the person frequents. Vacuuming is incredibly effective!
- When cleaning up clothing, don't forget to clean brushes, combs, hats, hair clips and hair
ties - minimum of 20 minutes in hot soapy water.
- Use an oil based shampoo (such as one that contains coconut oil) for daily hair washing and
for washing combs. Until the house and person are lice free, make sure dirty laundry is
stored in sealed plastic bags (or washed as above immediately) until washed to prevent
re-infestations. We used Dr. Bronner's unscented baby castille shampoo to wash combs etc.,
and for the laundry, since it contains coconut oil, johoba oil, and olive oil.
- Items that the person is around which are fabric (like stuffed animals) which can't be washed
should be sealed in plastic bags for a minimum of two weeks. Alternatively, they can be placed
in sealed plastic bag and frozen for 48 hours.
- Furniture, carpeting and floors should be thoroughly vacuumed daily. Vacuuming daily is highly
recommended! Toss the bag after each vacuuming! Don't waste your time and energy shampooing your
carpet or furniture - it isn't effective. Once again, pesticide spraying of these items is not
recommended - it's toxic, and it simply isn't effective. 1][3
- In a school setting, every child should be examined in the morning before being allowed in the
classroom by someone who is experienced in checking hair for lice and eggs. This
checking should be done using lice sticks (basically, cheap wooden sticks you toss in a plastic
bag that you seal shut and throw away) - a new pair of sticks for every child. Checking
each child with your fingers is a grand way to pass along an adult louse from one child
to the next. Children with lice should be sent home to be deloused. These sticks, btw, are usually
called 'pedicul-sticks' and are available from the National Pediculosis Assn.
- Children's clothing (hats, scarves, coats) should be separately bagged, not hung side-by-side,
using plastic bags, until all children are clear for at least two weeks. Make sure things like
'dress-up' clothing is not shared, and make sure things like hats, combs, brushes and sports
equipment lilke batting helmets, or electronic gear like headphones are never shared either!
Dealing with head lice is manageable and can be handled quite successfully via least
toxic means. My recommendations are based on research into non-toxic means, and on personal experience.
You should read the NPA and BIRC information for the full scoop. Keep in mind, once again, that this is
not medical advice, nor is it intended to replace medical advice!
The big key is to be meticulous about the steps you take. You will be most
successful if you also spend a few minutes using the BIRC and NPA resources to understand what head
lice are, how they breed, how long they live and their characteristics.
