Permethrin--Don't Bug Out Without It

By the same token, don't bug in without it, either.  Why is that?

Because permethrin kills bugs.  As mentioned in several previous blog posts on lice, ticks, bed bugs, etc. (links below), permethrin is the go-to insecticide in a bad situation.  Discovered in 1973, permethrin is also on the WHO List of Essential Medicines. 

PERMETHRIN AS A MEDICINE
Permethrin is available in a few forms, both over-the-counter and by prescription only.

• Nix is 1% permethrin lotion for killing lice.  It kills both the lice and their eggs.  It is sometimes suggested for killing scabies, but is likely not strong enough to eradicate them completely. 
• RID shampoo kills lice but not their eggs, so the treatment needs to be repeated a week later.
• Elimite, a 5% permethrin cream, is available by prescription only and is used for treating scabies.  It is applied from head to toe, including the hairline, under finger- and toenails, and between toes and fingers.  In babies, it is also applied to the scalp, but this is usually not necessary in adults.  The cream is left on for 8-14 hours and then washed off in the shower.  One treatment is usually effective. 

PERMETHRIN AS AN INSECTICIDE
Permethrin is an extremely effective insecticide.  It kills and repels mosquitoes, ticks, lice, scabies, fleas, and livestock parasites.  Due to resistance, it is becoming less efficacious in killing bed bugs.  Unfortunately, permethrin also kills bees, so it should not be used on gardens, though it is often used in commercial agriculture.

When sprayed on clothing, permethrin will kill and repel ticks and mosquitoes for six weeks or six washes.

Permethrin may also be sprayed on dogs to repel fleas and ticks.  If possible, their fur should be fluffed up before spraying, and permethrin should be sprayed all over, avoiding the genitals and eyes.  Permethrin is toxic to cats. 

Purchase options, in addition to the medical use options above, include the following:

• 0.5% Sawyer Premium Permethrin Insect Repellent; each bottle treats clothing and gear and dogs. 
• 10% permethrin from Martin's Multi-Purpose Insecticide. 
• 13.3% permethrin from Martin's Multi-Purpose Insecticide. 
• 36.8%  permethrin from Control Solutions Inc.  Each bottle contains directions for mixing your own solutions.  One teaspoon plus water to make 12.5 ounces of a 0.5% solution;  1 tablespoon plus water to make 37.5 ounces of a 0.5% solution (like the Sawyer brand, used for clothing, tents, dogs).

I like to keep things natural--natural medicine, home grown produce, cooking from scratch.  Diatomaceous earth and ladybugs for killing garden pests.  The yard surrounding my house is full of catnip and rosemary for repelling mosquitoes.  I also prefer to use products that are sustainable and renewable.   But I also want to be prepared for something truly horrific when it comes to ticks, lice, and mosquitoes.  If there is some kind of outbreak that poses a threat to my family, I need to be able to deal with it effectively.  If we find ourselves in tick country, we don't want to compound our difficulties with tick-borne illness.  If yellow fever invades with the mosquitoes, I want my homemade repellents to have a back-up. It's kind of like a pocket knife and a fixed blade knife.  The vast majority of the time, a pocket knife will serve well for whatever you need to do.  But there are those rare occasions when you really want a fixed blade, whether it's just for reassurance or for actual use.  Permethrin is that fixed blade.

Permethrin appears to be safe for use in pregnancy and for babies over the age of two months; however, breastfeeding should be discontinued during treatment.

Cautions:  Permethrin may cause an allergic reaction in individuals sensitive to ragweeds.  Side effects include a rash or irritation at the area of use.

Lice and TEOTWAWKI

Disclaimer.  I am not a licensed health practitioner.  This is just another post on an item you might wish to have available if needed so that a physician can treat you and your family as best as possible.  No medication, including those available over the counter, should be taken without consulting a physician.  Information shared here is for educational and entertainment purposes only.  It is not medical advice nor a substitute for licensed medical care.  A qualified, licensed physician or other medical provider should be consulted before beginning any herbal or conventional treatment.

None of my children has ever had lice, for which I am really grateful.  I'm not bragging, and I'm not asking for it.  But whenever I got a phone call saying that apparently my children might have been exposed to lice, it was like TEOTWAWKI, at least for a day or two.  All social plans got canceled.  Everybody in the house got treated and all the linens were washed, even though all the medical profession says this is unnecessary.  Whatever.  I can be open-minded and reasonable with colds, strep, influenza, maybe even smallpox.  But lice?  Oh, heck, no. 

(It's gonna sound gross, but I think my favorite "illness" as a child was lice.  I didn't feel sick. I got to stay home from school.  And my mom bought me a brand new bead set to keep me occupied making bracelets and necklaces and such.  What's not to love?  I was banned from playing with the girl across the street anymore, but she moved pretty soon anyway.)

We've got three kinds of lice to talk about here, and they have some things in common, but some aspects that are unique to each.

Head lice are what most of us are at least familiar with.  They're about the size of a small sesame seed.  They do not typically carry disease, but the scratching can compromise the skin and introduce infections.  Children are less bothered by lice; the bites don't cause them to itch like they do in adults, so they can become pretty infested before anyone notices.  Unfortunately, lice are pretty easily passed from one child to another, whether it's just in playing together or in sharing toys or combs and brushes.  If you happen to notice something suspicious and are wondering whether it's lice or dandruff, here's your quick and foolproof test:  Dandruff will flake and shake off; lice will not.  If you're still unsure, and you happen to have a black light available (not likely, but you never know), nits will fluoresce as blue dots attached to hair near the scalp. 

Body lice appear very similar to head lice, but they generally confine themselves to the body.  Body lice differ from head lice and pubic lice in that they live in and lay eggs on bedding and/or clothing, especially the seams, and only come out to feed.  Body lice are larger than head lice and can live thirty days between feedings.  They cause severe itching in an area of infestation, with small red, swollen bumps or welts often found at the base of the neck or torso where they feed.  Unlike head lice, body lice can spread disease.  They may spread typhus and are also associated with trench fever. (The recent outbreak of typhus in Los Angeles is attributed to fleas and not body lice.)  Left unchecked, they can actually bleed a person to death.

Pubic lice are difficult to see because of their smaller size and their preferred habitat, pubic hair.  However, while pubic hair is home base, they're open to checking out new locations like mustache or armpit hair or eyelashes and eyebrows.  They spread primarily through sexual intimacy and are considered an STD that is not prevented by using condoms.  Pubic lice do not transmit other STDs.  They can also be spread sometimes through sharing hairbrushes, towels, or clothing.  And they cause severe itching.

What are your treatment options post-collapse?  Commercial products available OTC include:

• RID 
• Active ingredients are piperonyl butoxide and pyrethrum extract
• Designed only for head lice, but physicians recommend for crabs and body lice as well
• Kills lice only, not eggs, so retreatment is required in seven days
• Do not use on individuals allergic to ragweeds
• Nix
• Permethrin-based
• Like RID, it is designed only for head lice, but physicians recommend it for crabs and body lice as well
• Kills both lice and their eggs

Natural remedies from The Survival Medicine Handbook:

• Mix salt, vinegar, tea tree oil, and neem oil (you're on your own for quantities) and apply daily for 21 days for head lice.
• Witch hazel and tea tree oil, applied daily after showering for 21 days for head lice and pubic lice.  
• Bathing with 1/2 cup borax and 1/2 cup hydrogen peroxide for 21 days.  

The authors of Survival and Austere Medicine, 3rd Edition suggest that if there is nothing else available, hair conditioner or some sort of oil (olive, coconut) can be used to smother lice and nits, and then a nit comb used to remove lice and nits.  This will take a very long time.  (This would not make me happy.  My daughters have waist-length hair.)  And it needs to be repeated a few times a week for a few weeks.

A clinical trial in Australia in 2010 showed that tea tree (10%) and lavender (1%) essential oils in a carrier oil with a shower cap were much more effective than commercial treatments.  Storing essential oils and shower caps may be less expensive than storing commercial products. 

Shaving works for eliminating all lice.  For body lice, an overall shave followed by several hot baths over half a day is most effective.

All linens must be washed in hot water--at least 140 degrees. Burning would be better, if it's an option.   Items that cannot be washed should be placed in plastic bags for two weeks (head and pubic lice) to five weeks (body lice).  Combs and brushes should be soaked in alcohol or hot water (140 degrees) for an hour.

Physicians often recommend Benadryl to relieve the itching.

The best prevention option, beyond strict hygiene and keeping clothes clean, especially when working among people who have lice, is to use permethrin.  Permethrin kills lice, but not the eggs.  However, it is long-lasting and will thus kill any newly hatched lice.  Permethrin is available commercially (Sawyer brand) in sporting goods stores where camping equipment is sold.  It comes in spray bottles to easily apply it to clothing and gear and lasts several weeks.  It is both a repellent and an insecticide and is effective for ticks as well.  It's also available in bulk quantities in feed stores.  How much do you want?  One doctor I know stores two to three quarts of this for his family alone.

(This article is the second in a series of posts on things that bite and treatments for them, beginning with the small bugs and working our way up.  Last week began the series with a post on scabies.  Next week will be bedbugs, followed by ticks, spiders, snakes, dogs and cats.  Apparently, I left out mosquitoes, so I'll have to remedy that and squeeze them in.)
