## 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: Great Value to protect your fur babies!!!!! - Every summer I have problems with my dogs with the flies around them. I read the reviews and decide to try it. Now it makes me feel mor comfortable knowing that they are not suffering from those flies. It is very easy to use, it is odorless. To me it is the best thing I have bought and even when I have bought many products before, so far it has been the best. Great Value for the product since it's not very costly, it is very effective, I will buy it again and again!
Review: Works wonders for my babies - I love this for my horses .. it's a semi strong citronella smell that seems to last most of the day .the horse don't mnd it .. plus buying it by the gallon last all summer long and I have it right at hand without running out .. the flys and bugs seem to stay away from the horses all day long . Which they enjoy very much. And it didn't make my horses hair all nasty feeling .. I think it's a really good product.

## 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
