Farnam Bronco Gold Equine Fly Spray Gallon

[This review was collected as part of a promotion.] Very thankful that SCAHealth offers the Bronco Gold. The farm stores around me no longer carry it. It seems to work best on my horses although a couple of the geldings show some sensitivity if the spray soaks in spots. I use fly boots and usually spray the horses (all have free-choice shelter) 2x a day. The effectiveness of the spray wears off after a couple of hours, it seems, but still much better than others I've tried.

works very well, kills flies on my horses.

[This review was collected as part of a promotion.] Bronco gold fly spray is our go to when flies are bitting. Long lasting.

[This review was collected as part of a promotion.] Good fly spray for horses. Smells great. Works well.

[This review was collected as part of a promotion.] This works great in our area. This is the only place I've found that sells it by the gallon at an affordable price. Will be ordering more to prepare for staying ahead of the summer and fall flies.

I live in Florida where flies & mosquitos are horrible. I have used all the fly sprays on the market. This is my favorite ! It works ! It lasts !

Doesn't do the best job at keeping flies off, even after a light ride on my horse without her sweating, I had to reapply after...within an hour.

Unbelievable that this is still on market. Look it up. Severe reactions for years. I got complacent and did not do my research. Sprayed it on my mare and she got massive swellings in underbelly, legs and now hair loss over a week later. Required vet call (dex, Banamine, antihistamines, etc.). I was truly scared. I have had her since birth, she is now 19, and NEVER had a reaction to any other fly spray. this stuff made her miserable!! Please don't risk it. I notified retailer AND Farnam. HSUS case was opened (per Farnam - not me). I wish I had never even looked at it.

I haven't had to post a negative review in a very long time, but others deserve to know my experience with this product. Do you see the lumpy patches that others have reported? Yup! MY HORSE TOO! I applied this fly spray one day. The next day I came back and my mare had clearly had an allergic reaction to it. Her skin thickened in lumpy patches on her barrel and belly. I didn't reapply the fly spray again, and fortunately the lumps went away after about 4 days. I thought maybe this was specific to my horse, or maybe that I got a 'bad bottle' (in which case, a negative review wouldn't have been necessary.) But my vet actually stated that she'd seen a lot of horses have allergic reactions to this stuff. I'm sticking with Farnam's Tri-Tec (20 years and 3 different horses, never had an issue) or a natural spray. DON'T RISK USING THE BRONCO LINE OF FLY SPRAYS!!! Farnam can be such a good brand, but this stuff is just terrible.

I had three different horses react violently to this fly spray. I have had horses for many years and have never had this happen. It gave them welts and blisters. I had a filly get so physically sick that we thought she had colic as well as having an extreme reaction to this fly spray. My show horse could not be ridden for almost 3 weeks and is still 4 weeks later recovering from the welts and blisters that literally had tiny pus pockets in 6 inch diameter circles that hair came off of. When it happened to my warmblood at PEC Sporthorses in Wilton, CA came up with weird welts and blisters a day after I put the flyspray on him - (I put the fly spray on one of my horses there but not the other the other horse is a Cremello and oil based fly sprays make the dirt come up.) After the welts and weird patches of tiny pus outbreaks/blisters I was apprehensive to think it was the fly spray but just in case the horse that had the reaction was sensitive to it (12 yr old I have had since born not sensitive to anything) -- I took the bottle home to my horses that are at my house (because I didn't think it was the flyspray). Several weeks later, the flies were obnoxious as it got hot again and I groomed and used the Farnam Bronco Gold on two of three of my horses at home. The one that I did not flyspray is a mini that nothing happened to. The other two horses reacted horribly!! It was put on Weds Sept 7th afternoon. I had a farrier scheduled Thursday Sept 8 at 9am. When he got there - I mentioned that my old mare had a weird lump on her tummy and it had looked like she itched it raw. I also mentioned my filly (3 yr old) seemed to be itching like crazy. As he was trimming one horse, we proceeded to watch the filly itch her side raw -- I ran and gave her a flake of hay to get her to stop. We both observed that it was odd. When the farrier left, it was about 11:00am. I fed them lunch at about noon. Then noticed about 4 pm that again - itching was dramatic. I went out to see that my older mare had welts running all over huge areas about a 1/2 inch rise swollen up off her. She had blisters similar to my horse at an equestrian facility in odd circles about 6 inch diameter with opened and dried pus pockets/blisters? My filly had huge welts smaller raised off her but she was acting bizarre. She would lay down and just look miserable then get up move around. I called my vet immediately. She asked me a series of questions which included did I use a different brand of fly spray -- when I remembered my other horse had reacted weird -- it all clicked..... She had me immediately give both horses baths with shampoo that was "soft" -- the filly felt better immediately but was still acting bizarre -- she was so happy after the bath - would run buck....go get a bite to eat then lay down. Because I know my vet well, she worked with me with phone calls. Anyone else would have had at least a $500 vet bill for this. I have continued to give them baths. My show horse could not go in the shows planned. This was bad. I have had horses for 40 yrs. I am not one to "freak out" about things. My filly's legs have sores/bumps all over in the areas that I applied the fly spray to the most. My warmblood is still growing hair in the areas reacting with the weird small pus outbreaks. My older mare has two big areas that are healing from breaking open. Please take this product off of the market - inform your buyers to pull it off the shelf.
