    Bug Check is rated 4.1 out of 5 by 287.
    Rated 5 out of 5 by from Bug Check I used this last year with not thinking it worked like I thought it should. This year I changed to a different kind that also had vinegar included thinking it would work better. Well was I WRONG!!! I changed back to the bug check after one month! Bug check is the best!!
    Date published: 2019-08-08
    Rated 5 out of 5 by from It’s Working I switched from Bug Off, which had worked really well for a couple of years, to Bug Check. It did the trick.
    Date published: 2019-08-05
    Rated 5 out of 5 by from It works! Bug Check has transformed summers here. The fly population is dramatically reduced and the horses are happier.

    Rated 2 out of 5 by from Disappointing Flies are still biting my mare and she is allergic to them as well......Platinum Allergy is the only OTC I have found that works.
    Date published: 2019-03-30
    Rated 1 out of 5 by from Disappointed Had high hopes for this but it did absolutely nothing. I've been using this going on 3 months at DOUBLE the loading dose and as soon as the weather got warm enough boom, the flies. I don't think it deters them from biting either. My mare still constantly bites at her sides and stomps her feet. I recently purchased fly stoppers, I'm hoping those little buggers will save the farm!

    Rated 5 out of 5 by from Bug check So happy with this product my horses all look good
    Date published: 2018-08-13
    Rated 4 out of 5 by from Seems to work It did take a while to work, and 2 of my 3 horses eat it with no problem. The one still gets enough in his feed that it seems to work. It is a pleasure not having to spray them so much and they seem happier without the flies. I normally don't use internal fly feeds but this is not chemical based so thought I would give it a try. Pleasantly surprised.
    Date published: 2018-07-26
    Rated 1 out of 5 by from Did nothing Followed directions and finished the container. Started before bug season and now that it's here, bug season that is, I see no difference at all. My guy is being eaten up and needs to be sprayed every day. As for the fecal, I see more bugs attracted to it now than before. I will try something else but this is a no go. The only good thing is that he liked it, but his breathed smelled horrible.
    Date published: 2018-06-07
    Rated 1 out of 5 by from MY HORSE HATED IT I love the idea of this, but, my horse hated it, he would not eat it at all. he even stopped coming in his stall when it was in his feed pan.
    Date published: 2018-05-24
    Rated 1 out of 5 by from Beware - Ingredients misrepresented Just received a 30# bag today. The first thing I noticed was the ingredient list on the bag doesn't match what SmartPak listed for ingredients. Instead of dried grape seed as the primary ingredient, it's actually brewers dried yeast, a much cheaper ingredient with fewer health benefits. Had I known the ingredients had been downgraded and cheapened, I would not have purchased this product. Very disappointing.
