Permethrin for ticks and other bugs

[alfonzo1955]

Funny, the Government of Canada publication on Travel Health and Safety entitled “Insect bite prevention” recommends applying permethrin on clothes as an effective preventative against infected insect bites like ticks that carry Lyme and other diseases, but strangely permetherin is not allowed in Canada: https://travel.gc.ca/travelling/heal...ty/insect-bite

I guess they want Lyme disease to spread by not allowing sprays like Sawyers to enter the country- makes no sense...

I tried the citronella scented horse spray and my hats off to you guys that can stand that awful smell throughout your hunt - it is really STRONG SMELLING and does not wash off easily. I applied some to my hunting clothes and it took 5 washes to get the smell off. I doubt any deer would get anywhere near this.

Also be careful about the stuff recommended by the OP - it has strong petroleum distillates in it and also has a strong smell - like diesel fuel.

Sawyers spray is the best for hunting (and our noses LOL) as it is unscented. REI used to ship to Canada but has stopped doing so.

If you guys know a Canadian source, let us know

Yes, it smells like paint thinner, but the smell goes away once it dries. I spray outdoors and let it dry. The one I linked is one of few Amazon sellers that will ship to Canada, less than $20 shipped to your door!

I took the Ministry of ag course to get my forestry exterminator's licence. Allows me to buy herbicides and pesticides. Got is so I could buy Garlon, Roundup, etc to control dog strangling vine and nodding thistle. Bonus is I can buy permethrin now as well at the agrico. Any farmer with their farm exterminator (sprayers licence) can buy it as well.

I buy horse and Maine from the feed store. It has permethrin.

I also use Ultra Shield on my clothes and it works well. Those of you who have a little grey hair (like myself) will find the smell of Ultra Shield to be the same as Ol' Woodsman, a bug repellent we used to be able to buy in the good old days. TC

I get the 36.5% permrethrin 32 oz bottle. Mix one ounce in a US gallon to get the right mixture. I also spray the inside of my boat down. It eliminates those ankle biting flys!!!!!!

+1 rick_iles.

By the way, for those individuals who think in metric units, the ratio to use is 1 tablespoon of the 36.5% permethrin to 1 liter (A.K.A. "1.1 quart") of water...

[Snip]

Not sure of the right mix ratio but I do know Connie2002's mix ratio is almost twice as strong as rick_iles. Please just read the label if you are using the product.

Not sure of the right mix ratio but I do know Connie2002's mix ratio is almost twice as strong as rick_iles. Please just read the label if you are using the product.

Not trying to nitpick, but although my ratio is really a bit higher, but not twice as much as rick_iles', because

a) rick_iles ratio is not quite correct. The correct amount is 1 2/3 US fluid ounce of the 36.8% stuff for 1 US gallon of water
b) This corresponds to 50 ml of the stuff for 3.8 liters of water (which is 13.2 ml to 1 liter of water - and one tablespoon is about 15 ml...).
c) So 1 tablespoon will give you 0.57% instead of 0.5%. As tablespoon's are different in size, you can be anywhere from 0.4% to 0.6% - and it really does not make a big difference in the effectiveness of Permethrin, I think...

OK, back to my cave now...

how much permethrin to mix with water

Hello, would you please help me with how much PERMETHRIN 10 I should mix per gallon of water to use in a 62o8 fogger? Thanks.

If you review the Permethrin Label, you'll see there is a wide range of mixture rates. In general, 2-4 oz will cover most any flying insect pest. So I would say to go with 2 oz per gallon if you're doing a maintenance spray. This type of spray is what you'll do whether you're seeing insect pests or not. In other words, if you're treating to make sure you don't get any pests, using just 2 oz per gallon will be fine.

But if you have an active problem, 4 oz per gallon or even more is acceptable in order to get a quick knockdown of the targeted pest. Permethrin can be mixed stronger as the label shows as much as 6 oz can be used per gallon of water if needed.

here is another;

Make Your own Permethrin Based Tick Repellent
The concentrated permethrin you want to buy to make a spray on solution for clothing is water based
NOT petroleum based. The water based product adheres to clothing whereas the petroleum based
doesn't. If it has a strong odor it is the petroleum based product; the water based product has a slight
odor. Amazon.co has 10% Martin's Permethrin which is water based. You mix Mix 1 part of Martin's
10% to 19 parts water to get 0.05% which is the same concentration as the commercial spray products.
The below article is one I found on the internet and it deals in depth about the options for three
different methods to treat clothing.

"Permethrin Fabric Treatment Options:
There are three specific dosages used to impregnate fabric with permethrin.
For protection up to one year (52 weeks): 0.125-mg permethrin per square centimeter of fabric. The
protection will last for the life of the garment, 50 detergent launderings, or 1 year, whichever comes
first. It is accomplished by applying a dosage of 1 pint of .8% mixture to a garment using Perma-kill
13.3% permethrin Solution by way of Controlled Wicking, Spraying or Soaking (see below).
For protection up to 6 weeks: 0.026 mg per square centimeter of fabric will yield 6 weeks of
protection or 6 launderings and is accomplished by applying 2-1/2 ounces of .5% (1/2%) mixture to a
garment by aerosol spray or non-aerosol spray.
For protection up to 2 weeks: 0.008 mg per square centimeter of fabric will yield 2 weeks of
protection or 2 launderings and is accomplished by applying 1-1/2 ounces .5% (1/2%) mixture to a
garment by aerosol spray or non-aerosol spray.

TOTAL FABRIC IMPREGNATION W/ PERMAKILL 13.3% SOLUTION ( 52 weeks ) Best suited for
fabrics of cotton and cotton blend. May darken light colors or pastels due to the quantity of permethrin
applied with this dosage. Clothing to be treated must be washable and suitable for exposure to water.
Dry Clean Only products should not be treated. Do not treat underwear. Controlled Wicking - This
follows the military procedure for personal application when spray application is not possible. The
process is a controlled wicking process where a specific amount (dose) of permethrin is introduced to
an individual garment under controlled conditions. You will need: a - pint measuring cup b - 1 ounce
measurer c - several 2 gallon sealable plastic bags (e.g. Ziplock ™) d - a bottle of 13.3% permethrin
Solution e - water f - clothing (Do not treat any under garments; treat outer garments only.) g - several
large rubber bands h - rubber gloves

Instructions: Wear rubber gloves when handling wet solution. Add 1 ounce of Perma-kill 13.3%
permethrin to measuring cup and top off with 15 ounces of clean water to make 1 pint. Roll garment to
be treated tightly to a size that will fit into bag and secure roll with rubber bands. Place garment into
the bag, add the mixed (1 pint) of permethrin solution and seal the bag while removing excess air. Put
bag aside for 2 hours minimum to allow thorough wicking. Remove garment, unroll the garment to
ensure entire garment is damp without dry spots, air dry, mark with treatment date (month/year) and
store. If wicking is not complete, roll garment and return to bag.

Note: Proper mixing of the permethrin with water by way of agitation/shaking is critical. Improperly
mixed solution will leave a blotchy appearance on fabric caused by the permethrin and water not being
thoroughly blended and/or separation during the wicking process. Make certain that you mix the
solution completely before adding to the bag containing the garment to be treated.
This method has been tested and delivers protection within the following guideline - Properly
completed, this procedure will impregnate the garment with a dosage of approximately 0.125-mg
permethrin per square centimeter. The protection will last for the life of the garment, 50 detergent
launderings, or 1 year, whichever comes first.

Note: Measuring cups (a) & (b) and sealable plastic bags (c), must be dedicated only to this process and
not used for ANY other purpose.
Spraying - Wear rubber gloves when handling wet solution. A respirator is recommended. For treatment
of a single garment add 1 ounce of Perma-kill 13.3% permethrin to measuring cup and top off with 15
ounces of clean water to make 1 pint of mixed solution in an appropriate pump up garden sprayer, or
trigger spray. Lay clothing out and spray until wet using one half the mixture, flip over and spray until
entire contents of container are applied, hang and let air dry.
For treatment of 8 garments mix 8 ounces of Perma-kill 13.3% permethrin with 120 ounces of water to
make 1 gallon of mixed solution in an appropriate pump up garden sprayer. Lay clothing out and spray
until wet, flip over and spray until wet, hang and let air dry. One gallon of mixed solution will treat
eight garments (@ 1 pint per garment) with the proper dosage of permethrin. See section on garments
for proper definition of garment.

Note: Proper mixing of the permethrin with water by way of agitation/shaking is critical. Improperly
mixed solution will leave a blotchy appearance on fabric caused by the permethrin and water not being
thoroughly blended. Make certain that you mix the solution completely before application and
occasionally during application.
Submersion - Wear rubber gloves when handling wet solution. Follow all instructions for Controlled
Wicking. Limit garment or equivalent (see section on garments for proper definition of garment) to 1-
pint of mixed solution. Substitute pail or other dedicated container for sealable plastic bags. Note:
Proper mixing of the permethrin with water by way of agitation/shaking or stirring is critical.
Improperly mixed solution will leave a blotchy appearance on fabric caused by the permethrin and
water not being thoroughly blended. Make certain that you mix the solution completely before
submersing garment.
Storage - The ideal storage is to pack into plastic bag after it's completely dry (black garbage bags are
perfect) and store in a dark place when not in use.
Garments - A garment consists of one pair of long pants (or an alternate of two pairs of short pants) or
one long sleeve shirt (or an alternate of two T-shirts). Garments to be treated must be treated
individually except when treating an alternate. When treating an alternate both items (e.g.: two pair of
shorts or two T-shirts) must be treated at the same time. An alternate pair must be made of like material
to ensure accurate wicking of the full dosage. Example - do not combine cotton blend with a nylon
garment.
PARTIAL FABRIC IMPREGNATION W/ .5% (1/2%) permethrin ( 2 or 6 weeks ) Other permethrin
Dosages - There are two other dosages that have been tested for clothing treatment. Both rely on a .5%
(1/2%) solution, which is available in pre-mixed 6-ounce containers (either aerosol or non-aerosol).
0.026 mg per square centimeter of fabric will yield 6 weeks of protection or 6 launderings and is
accomplished by applying by 2 1/2 ounces to a garment by aerosol spray or non-aerosol spray. Retreat
garments after 6 weeks or sixth laundering.
0.008 mg per square centimeter of fabric will yield 2 weeks of protection or 2 launderings and is
accomplished by applying by 1 1/2 ounces to a garment by aerosol spray or non-aerosol spray. Retreat
garments after 2 weeks or second laundering.
Note: For trips of short duration (6 weeks or less) the use of Duranon Tick & Mosquito Repellent at the
proper dosage is far more convenient than total fabric impregnation.

There are many recipes for use of this product while only three have been tested. Only rely on tested
methods for best protection. One frequently mentioned method is WRONG, here it is - Add the
concentrate to the final rinse cycle while washing your clothing. DO NOT DO THIS! First you will
over dilute the product thereby reducing its strength and effectiveness significantly. Secondly, you will
be flushing the excess product into the environment through sewers or septic systems. Always follow
manufacturer's instructions as the basis for use. This combination of permethrin treated clothing and a
topical deet based repellent on exposed skin is known as the DOD system (Department Of Defense)
and is recognized to perform at nearly 100% effectiveness. The deet repellent can be any repellent of
less than 35% deet concentration. Keep in mind that no protection system will be 100% effective and
that you must use other means to supplement the repellent. "

This stuff works quite well Lawn care companies spray it around peoples properties to rid them of mosquitoes.
