In the past, I've always used the Sawyer spray bottle stuff. I'd like to buy some permethrin concentrate to make it a little cheaper and possibly do the "soak" versus the spray on application. I've read in some previous threads that you should avoid concentrates that contain petroleum... however, upon further research, the Sawyer spray stuff also contains petroleum, just in a more diluted ratio (which obviously makes sense since the permethrin concentrate is "concentrated"). My research also indicates the petroleum in the permethrin blends is needed to help the permethrin adhere to the clothing (i.e. it allows for the permethrin to be effective). Two common concentrates I see out there are the Martins (10%) and the SFR 36.8% concentrate. Has anyone found one to work better than the other?
If you use some sort of permethrin concentrate (and not the sawyer spray), what do you use? have your clothes smelled after the application dried? (that seems to be a common argue against the concentrates). Are there any downsides to using the concentrate over the sawyer? It seems like the petroleum argument is the biggest argument against the concentrate I can find but its ironic because the Sawyer spray bottles contain petroleum also.

Well, that's interesting, and the first time I've heard that. I've been using a concentrate with no petroleum in the mix (as far as I know). It seems to be effective, but I wonder whether I'm not getting the effectiveness I think I am...

Been using a 10% mix for several years, Duration™ 10% Permethrin Concentrate.
I does list petroleum ingredients, but has almost no smell wet, nothing dry. Mixed as directed, will treat "16 complete sets of clothing" "One set of clothing = 1 long sleeved shirt, 1 pair of pants and 1 pair of socks" quoted from the link. This is accurate and does last thru 6 weeks.

For the past several years I've been using Hi-Yield 10% concentrate from my local farm store. I ran out recently when making a batch for one of my kids' summer camp clothes and ordered the SFR 36.8%.
I believe that mixed appropriately to the same final strengths, neither will be more effective than the other. The Hi-Yield does have an odor that mostly dissipates before first wear, definitely gone after a washing. Petroleum is listed as one of the chemicals.
I usually mix 1-2 gallon batches and collect the runoff for reuse.

I've used Martin's Permethrin SFR, 36.8% for about 8 years. It has a mild smell when it's wet but it completely goes away when it dries. 2 oz/gallon in a pump sprayer, very easy to spray a ton of gear.

I use the Gordon's 10% from Tractor Supply and have had good luck with it. I mix to .5% in a 5 gallon bucket and soak tents, clothes, chairs, basically everything and then let air dry in my pole barn for a few days. Slight odor when wet and nothing when dry. It goes a looong ways.

some of the stuff at tractor supply places stink and will continue to stink for weeks. will try to post a link later to what I have used that smells a little initially, but goes away when it dries.

drnatus: "some of the stuff at tractor supply places stink and will continue to stink for weeks. will try to post a link later to what I have used that smells a little initially, but goes away when it dries.Yup, have had that experience with product from TSC but I decided to double the strength so I thought it was my stupidity coming through. Took a while to wear off. Now I dilute only according to instructions and have had no issues. The product I am using now is Gordons Permetherin 10. I dilute it per instructions in a one gallon sprayer and use on cuffs, waists, socks, openings, etc. I do not try to cover everything. If I have product left I spray it on my house foundation.

The first time we treated clothes with permethrin, we used the Sawyer spray. Effective, but not cheap. A trail-runner friend told me about treating his clothes using concentrate, and I did several 'net searches before trying it. Too much emphasis was put on using a concentrate without petroleum, and I never found any, so decided to use what I could get at my local Tractor Supply (Gordon's 10%, about $18/quart). While the initial solution (reduced to 0.5%) had a mild odor, the dried clothes have no odor.
