I have been using this for years on my horse but for some reason the last bottle cause her to break out in hives. I am very interested in knowing if the formula has changed. May have to do research on manufacturing dates as the older bottle that had some left in it did not cause hives.

FINALLY SOMETHING SAFE THAT WORKS!!!!!!!

The recent stretch of sticky heat and humidity with those occasional annoying drizzles have made a perfect environment for flying gnats and mosquitos and no-see-ums

The recent stretch of sticky heat and humidity with those occasional annoying drizzles have made a perfect environment for flying gnats and mosquitos and no-see-ums to thrive. They swarm and constantly bite my recently-shorn alpacas to the point of drawing blood. Ugh!!! I tried everything that didn't help UNTIL I tried this product. I couldn't believe it, but it works! Not only does it work immediately, but its effect lasts a week or so...it is fantastic! I am so grateful to see Benelli and Damarcus "smiling" again. (BTW: not for goats, but that's not a problem, because for some reason bugs stay away from them...go figure!)

Poor shipping for liquids

Not sure where the shipping breakdown is happening between chewy and fed ex by another bottle of liquid came with damaged box and leaking everywhere! No packaging

Not sure where the shipping breakdown is happening between chewy and fed ex by another bottle of liquid came with damaged box and leaking everywhere! No packaging material inside box for cushioning and a damaged box don’t mix well!

Unfortunately didnt help

used on my horse legs and still flies are coming on. Not best for repelling. Also tried on stall floor and wall around the feed, didn’t see any effect.

It’s ok

Flies mostly ignore it but it makes a bit of a difference. It’s usually sufficient in a location where they’re less vicious, but not in Florida during spring/summer

Flies mostly ignore it but it makes a bit of a difference. It’s usually sufficient in a location where they’re less vicious, but not in Florida during spring/summer. It’s enough for the off season but might as well be water when the flies are at their worst.

Vet recommended fly spray

It seems to work but in Florida you need to spray every day which is safe to do. Chewy has the best price.
