When I need fly-protection to last for more than a few minutes, and can't use a blanket or mask, this is what I use. I do NOT run out of it, when I'm getting low (1/3 to 1/4 of a tub left) I re-order. It lasts a long time, both in terms of the tub and once it's applied. I do apply it with a disposable glove, because, yes, it sticks.
I love this product I wipe it on my horses nose under her fly mask and it works amazing! No bad smell or anything either.
The product works well def helps with the flies!
Swat has been my go to for years for any small area that needs fly prevention. It's great to use on ears and under belly for gnats and flys and any area that has a wound to keep flies off
It does stick dirt to it if the animal you put it on lays down. But it does keep nate off!
