Shadow "FREE"

Shadow is Maggie's friend and he has ALWAYS had a real problem with flies! They just love him to bits and he always has big bare bite marks on his chest every summer. Nothing has worked for him, while the other horses are relatively free from flies HE is covered. NOT ANYMORE! I tried this on him and was amazed the first day that he had no flies, then I expected that the next day the flies would be back, I kept expecting them everyday but for the recomended 3 weeks he has been free of flies! Just dosed him again but this stuff is amazing.

Spot On! Equi-Spot for the win - mostly for ticks.

While I didn't notice a significant reduction in flies on my three horses, I DID notice dead ticks after they came in from the lower pasture. I've applied this product, twice, on my three horses, two weeks apart. I live in the southern Piedmont of NC where plenty of flying, crawling, and otherwise annoying pests and insects are around. I consider this a win. For fly control, my other methods are: 1. disposable fly bags with attractant. 2. compost pile (manure and bedding from run-in sheds. 3. spread manure in pastures often with drag harrow. 4. fly predators 5. fly repellant spray and now 6. Equi-Spot. I'm happy with this purchase and feel the value for the money is equivalent.

I have been using this for 11 years on my horse. He never minded it until last year. I guess the smell bothers him because he can't stand for me to put it on, now. I tried putting some vanilla by his nose and that didn't help. I will get it on him, somehow, because it really works and he won't tolerate the fly spray. Thank you for not going up on your price!!!!!!!! Rhonda Smith

Learning curve

1st mistake, thinking this was a month long fly and tick control product, it’s 14 days. 2nd mistake, this is a spot control medicine for flies, so I now use it by hand and apply it all over my horses coat and nether regions. Once I figured these out it’s a solid product. I’ve noticed a dramatic reduction in flies and ticks.

Equi-spot 1st time use

Thought I would try it on my Fjords. Bought multiple packages and will be dillagent on applying it every 2 weeks. I will wear latex gloves after the 1st time! It is a liitle hard to determine "drops" at first, the product will come out quickly from the container. Not sure about how well it works yet....

Beware sensitivity and reactions

I used the Equispot spot treatment on two horses. One of which had a severe reaction within 5 minutes of application. Violent rolling, rearing, throwing himself against the stall walls. The symptoms disappeared as soon as I was able to give him a thorough bath to remove the product.

a must have for the plague of ticks and their diseases

my horse is just now recovering from a debilitating and expensive bout with lyme. I normally use equi-spot but stopped with the cold weather--big mistake! We had a few warmer days and he got at least one tick bite and eventually developed symptoms. He has never had a reaction or problems with this product and it has helped to keep him safe before. Most horses can tolerate it just fine and I feel that any risk from the chemicals are less than the devastation of these tick borne illnesses. BTW I had also used spray on products (both natural and synthetic) when discontinuing the eqi-spot and he still got bitten and ill. We have many many deer tick in my area. I really recommend using it if you do too. As a note, he didn't test positive and never had a fever but did have many other symptoms (severe soreness and stiffness, incredible loss of energy etc) and is making a full recovery with minocycline. Don't rely on the tests (they are often inaccurate) and listen to your gut if your horse seems unwell. The sooner you catch it the better.

works pretty good!

I had never used this product before but it did seem to work pretty well. I have 4 horses that hate the spray bottle so this was much easier than wiping them down at least every two days. I had to figure out how to get just a drop here and there, The applicator might need a little work. I like to put stuff on their belly, and it was hard to do with this.

It's just OK

This is our fourth time putting this on our horse. (My dad bought some through our local farm store, but I purchased this last one through Chewy because the price is better.) We've heard it takes time to build up to complete fly control. We still have flies, but worse than the flies are the horseflies. They just latch onto our girl and don't come off. Ugh. So many horse flies. Willing to keep trying this product to see if we just have to use it more, but will definitely be looking at a different product that can help with the horse flies better.

Horse Owner

I have used this for years. One trick to it working like it is intended to it to use it consistently throughout the fly season. Nothing works to keep 100% of any insects off but if you put this on your horse on a two week schedule, it’s like it builds up to provide the best protection. You won’t see the best control with just one application at first. But you will start to see it working after the second and third doses. So give it 4-6 weeks to take effect. And then keep using it all summer every two weeks!
