Why would I spend nearly $2k for the Pyranha 55g drum system, just to be able to dump the whole 2.5 gallons into 55 gallons of water, when I don’t need to do that?
Ultrashield black is now $75 for 1 gallon at TSC right now. I’d buy more than 3 of those ($225) to get me through 1 season with 3 horses. Let’s say I would use 4 of them (and it’s probably a bit more than tha), that’s 16 32oz bottles for $400.
OR, I could spend $235 and have fly spray for the rest of our years on this farm
I spent $80 last year on a gallon of Gordon’s Permethrin 10, to mix with a partial dose of a cheap fly spray (after someone here made that suggestion), to make a much more effective mix than the cheap fly spray, and at least as effective as the $75/gallon Ultrashield. We’ll leave the farm before I run out of the tiny amount of Gordon’s I use in a 32oz bottle. I wish I’d known about the fly system concentrate because I’d have done that instead.
I’d HAPPILY squirt 6oz into a gallon container and add water to it, and pour that into a 32oz bottle. I already make up a gallon at a time of my mix above.
