Questions & Answers

10 Customer Questions

Are there any negative consequences if too much is consumed? With multiple horses it is almost impossible to estimate the amount that each individual animal is consuming off the block on a daily basis, so is your recommendation 1 block per horse?
Answer by ChewyAug 01, 2021
Provide this block as a free choice source of nutritional supplementation for your horses. Start feeding this product early in the spring before flies begin to appear and continue feeding throughout the summer and into fall until cold weather restricts fly activity. Equine should consume an average of 0.15 milligrams of diflubenzuron per kilogram of animal body weight per day, to achieve control of house flies and stable flies. Equine should consume an average of 1.2 ounces of this product per 100 pounds of animal body weight per day, which is equivalent to 12 ounces per day for a 1,000 pound equine.

active ingredient?
Answer by ChewyAug 02, 2021
This product contains 90.8 milligrams of diflubenzuron per pound.

Does the block have any sugar? My horse has cushings. Is the fly block okay for my horse?
Answer by ChewyJul 30, 2021
This supplement contain cane molasses, which is made from the sugar cane plant. Due to your pet's diagnosed condition, we recommend consulting your veterinarian to ensure this supplement is safe to use.

Horses loved it

The horses loved it and devoured it right away as some other reviewers said. I am replacing it now. I did a number of fly control things at the same time. The sticky things do not have that many flies on them. The fly predator things have not had time to work. But, nonetheless, there seem to be fewer flies in the barn and on the horses. I am hoping that is from this block rather than just a momentary lull. I know it is expensive but the vet bill for one horse's eye inflammation from the flies and the cost of fly masks for all the others was not cheap. I would prefer not to require the horses to wear the masks, and of course, no more vet visits and bills would be nice too. So, am ordering another block. Will report in if I think this does not work but I am optimistic that it already has.

My experience

I have a 28 year old horse. He had a really bad reaction to the pesticide that is in the block. He lost all mobility in his back leg. He was having muscle trimmers, he was extremely sluggish and drenched in sweat. We removed the block. Gave him a cold bath, gave him his grain with vitamin powder. Got him to start eating grass and after several hours finally got some mobility back in his leg. It was extremely scary. Please be careful feeding this block to your horses!

Safe for pregnant and nursing mares

I have 7 horses, one that is pregnant and one with a foal at the side. I bought 4 blocks just to try and boy was I impressed. The blocks lasted my horses a little more than a week. I noticed right away that there were little to no flys on my horses. I haven't been able to buy anymore yet but I would definitely recommend these. My stallion also got injured with a giant 3 inch deep cut in his shoulder. I couldn't stitch or wrap it so it had to be left open and cleaned. And usually flies are drawn to these injuries like no other but after trying these flies didn't even touch him. I use these blocks with simplifly and the fly population is way down. I was a skeptic but now am a believer. Definitely will not go another fly season without them.

A different method of use

When I got this product I bike it into large chucks to put in there grain buckets like I would do with a salt block, all 3 of my horses ate it so fast. I went back to the drawing board. I decided to crush it up since it was so soft. Now I am adding it to their feed as a supplemental in 1oz servings. Are the flies at this time aren’t bugging them nearly as bad as before I started doing this. Plus I am not going through the block super fast. It’s takes time to crush it but this method seems to be working and I am not noticing and negative reactions on my horses end.

It's great

I had to chuckle at the "my horse ate it" complaints. Haha kinda the point of you ask me. Glad I ignored the reviews and tried it. Yes it's not hard like salt blocks, because well... It's a mineral block. That's great for the oldies to get extra minerals. I highly recommend it. Is it cheap? No. Is it quality? Yes. Are your horses going to eat it? Also yes. They're going to gorge themselves at first because they're most like deficient in a mineral of some form. Once their system adjusts, they last like any other mineral block except with amazing fly control

Fought over and eaten in days

Our horses liked it, too much. They spent a few days fighting over it until it was gone. Will get a plain salt block next time.

Works great

We use this for our Mini Donkey and our pony. Our donkey does not seem to touch it and is constantly being but by flies. Our pony on the other hand does use it and she has ZERO fly issues this year!! The block will last her 3 to 4 weeks. Expensive but worth it.

Waste of Money

My first block lasted 3 days with 2 horses free choice. I thought that maybe it was bc it was new and tasty. Well my second one came and I put it out while my other horse was gone to a show. So it was just the one horse and it was gone in less than 3 days. What an absolute waste of $60!

Not worth it

I really wanted to like this, but unfortunately it doesn't last at all. I bought 8 of them for my barn, and they were all gone within 2 to 3 days.. I'm sorry to say but a total waste of almost $300

Didn't last long enough to evaluate!

My two average size horses made this disappear in 3.5 days. So i am not able to correctly review this items accuracy. This item is way too expensive to only last my horses 3 days. I think this was made a little TOO appealing for consumption.
