Safe for use on horses, dogs, and around barns or kennels, it offers non-oily, long-lasting protection with a pleasant citronella scent.

## Description

Bronco E Horse Fly Spray Plus Citronella is a barn essential for horses, dogs, and the spaces they share. This water-based formula kills and repels six types of flies (stable, horse, face, deer, house, and horn) plus mosquitoes, gnats, ticks, deer ticks, lice, fleas, and chiggers. Safe for horses, ponies, and foals, it also works as a premises spray in barns, stalls, trailers, and kennels, and is safe for use on dogs. The non-oily formula won't leave greasy residue on coats, tack, or surfaces. The fresh citronella scent is noticeable but not overpowering, and works alongside the active ingredients (permethrin, prallethrin, and piperonyl butoxide) to help deter insects from the area. Apply as a light mist for full-body coverage or use with a cloth or sponge for sensitive areas like the face, ears, and muzzle. Available in a 32 oz spray bottle or a 128 oz gallon refill. For complete fly control, pair Bronco E with Farnam SWAT Fly Repellent Ointment for sensitive areas, SimpliFly Feed-Through Fly Control to stop flies before they hatch, and the SuperMask Horse Fly Mask for proven face protection.

Review: Works great 👍🏼 - The summer heat hit, and my two GSD's were getting swarmed by flies everytime they went in our backyard. I poured through reviews/products to find the thing that would work, and this was what I ended up purchasing. The smell is a very strong citronella smell. I love that smell, so there is no bother there. One spray down lasts each dog about 3-4 hours before I need to spritz them again, which I think makes it pretty effective. We live in a heavily treed area, so we have plenty of bugs/flies. I have noticed some dead flies after spraying, so that's a plus! The sprayer is also very generous and has a large mist area, so I have to spray less. It's a very thick, durable sprayer which is cool! My doggies are definitely way happier now that the flies are leaving them alone for longer periods. They were so stressed out constantly trying to evade/snap at those flies. So I am thankful I found something that actually works and aids to my dogs' health! I feel like the price is great too! At this rate, I feel like this bottle will last us a bit before I need to buy more. Overall, I am super satisfied with my purchase 😊
Review: Best fly spray ever ! - Only fly spray we use. We have dogs and it’s safe for them , smells great and kills flies fast. Use inside and out ! Value is amazing. Lasts for a long time.

## Questions & Answers

**Q: Can this be used on cattle? 🐄**
A: I don't know without reading the label, but I do know it only lasts a couple of hours.  For that reason, I don't know how much good it would be for you.

**Q: can i use on pregnant cows or lactating cows that still have calves?**
A: I wouldn't.  I checked the bottle and there is a list of farm animals it can be used on, but cows was not one of them.  It does state over and over that it is highly toxic and should not be used around any kind of feed, so I would say, no.

**Q: How is this dispensed?**
A: it does not have anyway to dispense it. you have to put it in a spray bottle or you have to buy a sprayer for it.

**Q: We have a lot of flies in our yard/patio how often should I spray the yard/patio.**
A: This item should be used after each rain at least

### ⭐⭐⭐⭐⭐ powerful weapon against flies!
*by S***Y on July 7, 2025*

This has been the most important product in my house lately. Our neighborhood has a feral colony of cats. I think they've all been to my house as kittens for one thing or another. I fed them on the porch where it was sunny and warm all winter but I needed a different solution for summer. I purchased the Veehoo Portable Dog Playpen - Medium here and lined it with a sisal mat and a feeding mat. Then I sprayed the whole thing and its contents down with Bronco spray. Each week when I clean it I can tell that it's reducing my fly population significantly. The cats don't mind the citronella odor and I love it. It has also prevented flies from entering my house when I open the door!
