Questions & Answers

7 Customer Questions

Are all of the Ultra Shield fly sprays water based?
Answer by ChewyJun 09, 2020
Absorbine Ultrashield repellents are water-based. Water-based fly sprays are not an irritant for most horse’s skin, and won’t attract dirt or dust. It’s not always easy to determine if a fly spray uses a water or an oil base. The easiest way to tell is to look at the bottom of active ingredient listing. If you see the statement, “Contains Petroleum Distillate” then you know the product is oil-based. For a complete list of ingredients, click on the 'Nutritional Info' tab, next to the 'Description' tab, just under the product photos.

How many regular sized bottles does this end up making?
Answer by ChewyMar 18, 2021
This repellent refill is 128 ounces. If you are filling a 32 ounce sized bottle, it will fill 4 bottles.

does it work on chicken for northern mites and red mite?
Answer by ChewyMay 18, 2022
This spray cannot be used on a chicken. We recommend using the Absorbine FLYS-X Natural Fly Repellent Dog & Livestock Spray available on our site.

Can this be used on a pet cow? She is a black angus.
Answer by ChewySep 26, 2021
Ultrashield EX cannot be used on a cow. It is recommended to use the "Absorbine Flys-X Spray" instead.

Product great, packing terrible!

I decided to order this fly spray from Chewy as I have previously bought it elsewhere, since I was having another Chewy order delivered. Someone threw this bottle, un-wrapped, on top of my dog and cat foods, where it leaked from a loose cap. I did call customer service and they suggested that in the future I ask for it to be sent separately, so that’s what I would suggest. I have always felt that Chewy was a superior company but that their packers needed some education.

Great Product, Great Service

I've used this product for years and continue to be pleased with its efficacy. There was a problem with the delivery of the Ultrashield due to damage in shipping. Chewy quickly delivered a replacement. Thanks, Chewy

Best Spray

Keeps the flies off. Bear in mind that this is an insecticide as well as a bug repellent, so I am not sure of the overall environmental effects. But it does get rid of the flies and does not seem to harm the horses.

Good stuff

I have a TB that gets hives & this fly spray works great & helps him not get hives. I like how it’s already mixed in the gallon jug too.
