Better than most

Used it for years and its the only spray I use, but it’s not true when they tell you it works for three days. I need to put it on every day especially for deer and horse flies.

UltraShield® EX Insecticide & Repellent

UltraShield® EX Insecticide & Repellent has been my 'go to' fly repellent for years. NC summers have all sorts of biting flies and using UltraShield® EX Insecticide & Repellent works well for field and forest hacks!

Ultrasheild effectiveness

I live in northern Alberta Canada and have 2 donkeys. I can spray in the morning and by evening I need to spray again. It doesn’t even keep the mosquitoes away for a day never mind other pests. Your label on the product of 17 day effectiveness is false. Maybe you need to change the formula.

Wonderful product.

I love this fly spray. It works better than most. I’ve used it for years. I love getting the spray bottle along with the gallon jug of it.


I didn’t realize this is so dangerous. I would like to return it. It’s dangerous to breath, touch, smell everything is not good about it. I can’t use this on my horse :(
