Permethrin Cost Comparison $$

[Snakelover]

What is the right ratio to get .05% for treating clothing. I have the tsc .10% and it has all the instructions for patio, animal, yard, spot spraying.... but not clothing. Kids will be wearing this so I dont want to make a mistake. How are yall mixing it?

I think you have some decimal points off there. Sawyers is not .05%, it's .5% (one-half of one percent). And the product you bought is probably 10%, not .10% (I'm assuming).

You first divide the % permethrin of the product you bought by .5 and that equals the total number of parts solution that you want to end up with. Since the original product itself is one of those parts, you subtract 1 from that number and that equals the number of parts water that needs to be mixed with the product to yield .5% permethrin.

Examples:

If your product is 10% permethrin.... 10 divided by .5 is 20. 20 parts total minus 1 part product =19 parts water. So mixing 1 part of that product with 19 parts water will yield 20 parts of .5% permethrin.

If your product is 36.8% permethrin.... 36.8 divided by .5 is 73.6. 73.6 parts total minus 1 part product = 72.6 parts water. So mixing 1 part of that product with 72.6 parts water will yield 73.6 parts of .5% permethrin.

An extreme example that will help it make sense... If your product is 100% permethrin.... 100 divided by .5 is 200. 200 parts total minus 1 part product =199 water. So mixing 1 part of that product with 199 parts water will yield 200 parts of .5% permethrin.

By the way, in thinking about all this and after reading Rchr's post, I realized I had miscalculated slightly in my first post because I didn't account for the one part product. I mixed 1 part 10% permethrin with 20 parts water (instead of 19 like Rchr stated). Which means my resulting solution was .476% permethrin. Still close enough to .5% for all practical purposes, but henceforth I will mix with 19 parts water.

I've been using this and can not tell the difference from Sawyer's. Just a lot cheaper.

So 19 to 1 to = the sawyers mix is the short answer. Thanks snakelover. Great explanation too. Thank you for breaking it down for me.

Great stuff! I've been using a similar product for several years. It keeps the ticks off when working around hog feeders too. Which is the main reason I use it. And last for a few weeks. I keep my clothes in a zip-lock bag when not in use, to help preserve. I also mix it on the strong side and spray down tent type ground blinds to help keep the spiders out. Leaves almost no smell after it drys.

Been using permethrin for years and it works great and last through several washings. Just ordered the Martins you posted and will have it in a few days. Might actually dry out enough at the lease to go out there in a month or 2...

[mt2078]

Martins also makes a 13.3% permethrin that is doesn't retail for much more than the 10%FYI.

[BURTONboy]

Going to order some of this. Thanks for sharing

[RAGUIRREJR]

I need to start mixing my own! I've been buying the premixed one for too long now.
Thanks for all the input guys

Snakelover,

There isn't an issue with dunking. Put clothes and mix in a bag and shake. I don't wring them out, just use a pair of the long yellow dishwashing gloves to take clothes out and hang to dry. Been using the military kits for 20 years.

Also, I did a fair amount of research last year and it appears there is a different binding agent added to the stuff specifically made for clothes. So, I use sawyers for my clothing and mix my own for tent, gear, etc.

So if I have the Permethrin 10 from TSC I would mix 1oz of Permethrin with 19 0z of water for a 20 mix of .5% Permithrin? Would this be what I need to spray on my clothes and boots?

TSC now has an 8oz and one larger size in stock, at least in Lubbock.

Yes, Doug. I looked at the TSC website just to make sure of the percentages. They list a quart of Gordon's Permethrin 10 for $19.99. But then they show a picture of an 8 ounce bottle. I'm assuming they're just using the same picture for both sizes because last time I checked a quart was 32 ounces.

This cracks me up reading this....Amazon.com. ..really? Every feed store in the state has it on the shelf all the time..... have ya'll ever walked into a feed store? Come on people get off the computer and support the small people that are scratching out a living.

Permethrin is also used to re-soak used thermocell pads, which can then be re-used in your thermocell instead of purchasing the high dollar new pads. There ar some youtube videos of how to mix it and re-treat the pads. Another money saver.

yeah i am going to do this for sure!

[muzzlebrake]

Permethrin is the synthetic version of the real thing called Pyrethin and is much cheaper. Pyrethrin is what is generally used in Dairy barn automatic spray systems and is more potent. Kills stuff drop dead flying thru the air and is the safest insecticide there is. I use the synthetic stuff because it's cheaper although not as good.

I don't even know where the nearest feed store is let alone set foot in one. Amazon is only a few clicks away!
