Long lasting
Best spray I’ve found in years. Lasts longer an sticks well w oily consistency. Use it on cows horses an even spray around chicken coop keep flies away. Keeps ticks of live stock also. Even used around my front door but b careful is does have oily base. Don’t track on your floor or stain ur concrete even w a very fine mist.

It really worked.
Started working on the cows few minutes after I applied it. I used a small gallon size sprayer. Will use this product again.Good value for the price.

Just thick enough….
To use a syringe to put down our sheeps’ backs and use a teeny bit of the dogs (they’re 120 pounds). I do recommend pouring the liquid into a smaller bowl to draw it up easily.
