Rated 4.1 out of 5 by 18 reviewers.
Rated 5 out of 5 by INCREDIBLE i started using this product last year and it's effectiveness. i have a black filly that the bugs just LOVE! she would have a strip down her belly at least 4" wide that would be raw. then her chest and face would be next. about august she would loose her mane due to the gnats. this product has been a life saver - for her and me. i no longer have to put her on prednisone every other day in august, and no more expensive creams to cover the sores. i start it in april and will feed it till november. it really works.

Rated 5 out of 5 by it is worth it I think this product works. I was not sure at first, when I went to buy it. The fly spray was not working so I gave this product a try. My QH mare was always being ate up; blood on her legs from the flys.Since I have been using this product that is gone. I might use fly spray once, maybe twice a month. I would give this a try. It is worth the cost especaially since the fly spray was 20.00 a bottle too. July 19, 2010
Rated 4 out of 5 by Incredible I put both my Geldings on Bug Check about 3 weeks ago. The Arabian was biten up and in hives, that is all gone. He barely has a fly on him now and sure no biting flies at all. Even the gnats leaving him alone now. The Quarter horse still has a few flies on him, but he also has no biting flies around him, very few gnats. At first I thought they would not eat it, but they licked the buckets clean. Honestly for the price it works miracles. I might up the dose on the Quarter horse for a few more weeks and see if that will eliminate his flies also. Overall I am impressed by this product. The price and the results beat the pice I would pay on fly spray who would only work for so long. June 9, 2010
Rated 4 out of 5 by palatable i havent been able to use it consistently enough to comment on its effectiveness, but i can say it is highly palatable. it seems like a lot of additive to use per day, but even my pickiest picker ate it in a small amount of pelleted feed without noticing! May 25, 2010
Rated 5 out of 5 by finally something which keeps bugs away! awesome product! Living in Florida you constantly fight against flies and mosquitos...I'm using now my 3rd jar since winter finally is gone and I must say: there is hardly a fly around my horse! Even almost none in the stall on her poop! It is so worth it! May 23, 2010
Rated 5 out of 5 by really working! living in Florida you deal with heat & humidity: lots of flies but also los of mosquitos! for now I'm very pleased, I'm using the 2nd bucket, but it's only May, will have to see how it will be in July/August when all Mosquitos are present! May 3, 2010
Rated 4 out of 5 by INCREDIBLE!!!! After spending more than $150 per year for fly spray for one horse with short term results, we decided to try Bug Check. This stuff is FANTASTIC. Flies will come near, but rarely land on our horse. Every horse in the barn we are at is on Bug Check, and all having the same results. I wish we had tried this sooner!!!!! April 15, 2010
Rated 4 out of 5 by Awsome stuff. This stuff is awsome. I have two geldings who stay out all the time. When tick sesson got here it was awful! I would pick 5-8 ticks a day off of on horse. Now since being on the Bug Check I get might pick one off once a week. It helps with the flies as well but you have to be realistic, it doesn't keep the flies off the horses 100%. Any relief is better then none. August 6, 2009
Rated 4 out of 5 by Bug Check works My black mini has gotten eaten alive, literally everysome by flys, even fly spray only worked for a couple hours. His little legs would get raw spots on the insinde of his hocks & the inside of his front legs. This happened for 5 summers in a row. This summer I started feeding Bug Check in May & he has no bug bites at all! His coat is gleaming black too, no sun burn browning on him at all! I live in Arizona, so I thought there was no way this would work, but it does very well! July 23, 2009
Rated 5 out of 5 by BUG CHECK IS #1!! This product is unbelievable. It really works! One of my mares would break out in hives with every bug season since she was a 3 yo. I tried everything from fly sheets & sprays, to acupuncture & Chinese herbals. The farm is kept as immaculate as a farm can be kept including proper manure management & parasite control. I was at wits end until I tried Bug Check. Within 2 days her hives were gone. Within 2 weeks her coat was beautiful. Maybe she was just low on thiamine, which is one of the ingredients, but all I know is that I am keeping her on Bug Check. It really is amazing stuff! May 29, 2009

I've been using this product for 8 years. It does a good job keeping the fly population down. My horses don't have problems with flies. I would recommend this to anyone who has horses.

i have a red horse that the no see ums get to him.i am hoping this works for him
DIANE G on Jan 23, 2015
This is the first summer I have used this product. I reordered it and it seems to be helping the fly issues. There are a lot less around the fresh manure. Will know for sure when the weather gets hot.

Is this ok to feed with the sho glo vitamin supplement?
Susie on Jun 17, 2015
Best Answer: I'm sorry, I don't know the answer to that question. I have never used sho glo. If I was you, I would send an inquiry to the Natural Vet, the company that makes the Bug Check product and find out from them.

Is this product ok for cows too?
Gayle S on Jul 22, 2015
Best Answer: Yes, it is great for cows, sheep, goats etc. They make a separate formula for dogs, cats. I have used this for 5 years on my two horses. I buy the 10lb. size. I swear it works on most flies but the gnats and horse fly are still around. I use this and the fly predators and the big fly traps. This year is the first year that I bought the formula for dogs and cats. Everyone was complaining about the bad flea season and I never saw them scratch. The horse are ok with the taste, the cats hate it. This won't eliminate all flies but it sure does help keep the livestock a little more comfortable.

What happened to the larger size? I'd like to order the 30-lb size, not 2 lb!
ASHLEY M on Mar 17, 2015
Best Answer: Oh no, I hope they still make the larger size! With 4 horses the 2 lb is not enough. I hope the manufacturers respond.
