Flies, I hate them

So at the minute Roley is really struggling with flies. There everywhere. We can't seem to find a spray that works, I'm going to try and research about fly sprays that might work. Any suggestions for in mean time he wears necked fly rug and occasionally fly mask (but tends to lose it in field). Any good fly sprays out there?

I (also uk based) use deosect as recommended to me by our RVC vet and on here - you have to dilute it and essentially "bathe" them in it. It's quite strong and not something you should be doing even weekly. You HAVE to wear gloves and do no get it in your eyes! Do a test patch the day before and make sure to avoid their eyes and sensitive areas etc. It really gives me a bad chemical burn if I get on me. But my horse who is unclipped and thick skinned has no reaction. Some come out in hives and can't deal with it so be aware. But I've found it really depends on the horse. If it rains or she has a bath then it needs re-doing, I might use a slightly weaker solution if it's too close. I found that normal fly sprays need daily appliance sometimes even twice o.o. Deosect definitely seems to do it's job better and longer from what I've observed. Other things that I found helped was good poop and field management. It's no surprise the yard where the field isn't poo picked at ALL has the worst fly swarms I've ever seen to the point of stressing the horses out badly made worse by the fact that they don't even rotate fields ;/ The yard where staff poo picked ALL EIGHT fields daily had very little issues with flies at all.

edit: I also try to not use scented shampoos or conditioners or if I do I try to let them roll it out as well. Unsure if this specifically helps but I do it anyway!

Thank you. We are at a lovely DIY livery yard where he has two of his own fields and we poo pick every day. Luckily after tomorrow it is apparently set to get cooler so flies might die down but we'll see how it goes thanks for help again.

Fly boots are also an option.

I've yet to find a great fry spray.

Feed thru fly control works wonders. I used to work at the SPCA and we took in neglected horses in addition to the other animals. Flies were awful when I started, in all the buildings etc. I used the feed thru at my house and flies were almost non existent after I started using it. I got them to try the product (11 cents per day per horse) and within 2-3 weeks flies were almost totally gone. I know the neighbors loved it! When the horse manager went on vacation for 3 weeks the staff quit feeding the product and within about 10 days we were back to flies everywhere. When Kaycie returned and put everyone back on feed thru, within 2 weeks we were back to almost fly free. The product we used contained dimilin, which halts the development of the larvae in the manure. It also does not affect earthworms as they do not have the hard body shell. Just a thought.

We have deer flies and horse flies. Nothing works on them! Nothing! They laugh at fly spray. Permethrin helps but doesn't stop them from swarming.

We just get the usual house flies but they are horrible roley hates them they bother him in a fly rug and mask. Imagine if people invented a fly spray that actually worked! It would be a dream come true!

Only thing that works for me on house flies (non-biting) is obsessive sanitation and regular release of parasitic wasps which attack fly larvae. You may not be able to get them in the UK but they are very popular and effective here. Fly masks and fly sheets with necks bring a lot of comfort to the horses.

Nothing works on the biting flies, ugh. I hate them, my horse hates them. We hate them!!

Flies. The bane of my existence...

I've yet to find a good spray. At this point, I'm almost tired of trying since they don't seem to be making any difference! I do however, have quite a few fly traps set up across the farm. They work pretty well on the non-biting flies but I've yet to find a way to keep the biters away. I currently have fly sheets coming in the mail as well as a feed-through supplement.
