Permethrin 10 concentrate--best RATIO

[One_Two_Three]

I know there are other threads on this, but I’m kind of confused about the dilution for flyspray, and none of the threads really addressed that, or they did but the differences were SO extreme that I wasn’t comfortable proceeding without getting a better idea of what’s going on.

THIS
is the concentrate that I got.

The directions ON the label say for horses anywhere from 1.33 to 2oz per 1 gallon of water.

People on here have said .5oz to 32oz water…

some say 1oz to 32oz water…

Then we had the sob story about how someone blistered their horse’s skin at the .5oz to 32oz water mix.

Anybody have any insight?

The sprayer I use is a standard 32oz “horse sprayer” fly spray bottle. I obviously don’t want to melt my horse’s skin off, but he’s coming in welted on his chest from bugs, and before I run to fly sheets (it’s so hot here) I thought i’d just try a different fly spray than what I’ve been using (repel X concentrate with white vinegar)

I suppose following the directions would land me at, roughly .25oz concentrate to 32oz water, if my math is correct…but i’d like other’s opinions and experiences.

I have no idea if this is the same product but I use permoxin, which is 10mm of permoxin to 400mm of water.

I have used it for several decades on all breeds of horses and I have never seen it burn.

It is an insecticide not a repellant.

I am using the same concentrate. I am using at the dilution of 1oz concentrate to one gallon water. I mix the concentrate into a plastic gallon jug (cheap water jug), shake well and then apply by dampening a rag and wiping on. I recall reading something about not wanting to inhale it. I’m sure its not good to inhale any fly spray, but using this concentrate freaked me out a bit to begin with, so I’m being cautious.

My horses have not had any negative reactions to this ratio, and my liver chestnut is particularly thin-skinned and reactive in general.

I suppose my brain should have thought that I could mix it up in a jug and then fill my spray bottle if I so chose to…duuur…

I read on the list “do not inhale” but I feel like I’ve inhaled a heck of a lot of fly spray with lots of other junk in it…and they did have a direction for a ‘sprayer’ type system for the concentrate–but the dilution was questionable for me.

I’m glad to hear you’ve had no reactions. My horse isn’t a particular delicate flower when it comes to chemicals, that I know of. He’s had all the commercial preparations applied with no issues, he’s just sensitive to touch on his skin. But the other thoughts people had about blistering is why I became a bit concerned. I guess mileage may vary on this, as with everything else.

Perhaps I won’t spray on him and turn him out…I’ll spray on him in the morning and make sure we don’t have a reaction first.

I put 1/2 oz in the 32 oz fly spray bottles. I’ve yet to have a problem with it on my 2 mares - and the sorrel has some pretty bad allergies to most store bought fly sprays.

Perfect. This is what I’m going to try. I don’t forsee any issues, I just had seen some people in the past post that they had issues but didn’t disclose the dilution rate the used.
