Any way to prevent bot flys from laying eggs?

I've noticed this week that the bot fly have made their appearance on my horses legs and sides. Yuck! I hate those little sneaky flys! So, everyday I have been scraping those nasty little yellow things off my horses legs with my bot knife. Good thing is that by keeping up on this every day, the number of eggs is small. Then I re apply fly spray all over my horses. It's getting annoying to have to scrape them off daily. So is there any way to keep them from laying their eggs in the first place? What if I applied some Vaseline to those bot laying specific areas? Would that work? Help please! :)

Seems to me, I remember someone saying they wiped down their horses`legs with mineral oil. Unfortunately, I don`t remember if it was successful or not but at least it would be easier to put on than Vaseline. I think it would create a non stick surface so might be worth an experiment.

That's what I was thinking, if it made the hair slippery, then the flys couldn't lay their eggs. Just any idea.

I'll have to subscribe to this thread as I'm curious too.. Major gets plenty of them, and it takes a good five minutes to get most of them off.

Also, dogs can get them as well.. although it's not nearly as common. Just recently, my 5lb Papillon had to get a larvae removed from her leg as she somehow managed to get an egg laid on her and we never noticed so we couldn't get it off in time. We originally thought it was a bug bite, but after asking around online, I found out what it was and we got her to the vet.

What about Swat? Could that be applied to the legs and repel bots?

Best is good grooming, and keeping horse's area as fly free as possible. Fly spray, cleaning stall, and checking for eggs, and removing them.

And worming too helps, with a boticide.

Horses make me a better person.

Bot flies don't land on the horse - they shoot those ugly eggs out of their tail shoot - like a torpedo - and that is no joke.

Notice in this link, the words "while hovering" are used Point-being there isn't a fly spray made that keeps them from laying eggs on the horse.

What I have noticed is that it seems every other day is "Busy egg laying day". I also notice that, as we get closer to Fall, the stickier the "stick-um" is that holds the eggs onto the horse. I deal with bot flies during the entire warm season and have noticed the eggs don't stick on the horse near as well in late spring as they do when we're getting closer to Fall.

The above link also talks about nose and throat bot flies. The eggs left in the nose and throat area can't get licked so how do they get into the horse's system one might ask? They crawl their own way into the mouth<--just when you thought things couldn't get any worse.

I see them on my horses' jowels every year - some years worse than others.

Except for attracting dirt, the mineral oil is a good idea.

I will also use it or some kind of ointment on the jowels just in case I missed any bot eggs in that area.

I also keep that hair shaved pretty close so they're easy to find. Which works for finding ticks, as well

I was just thinking about this the other day as I scraped some eggs off my mare. I'm lucky, she's bay and the eggs are easy to see. For those of you with light coloured horses, I was thinking that to remove them, I wonder if you could do vinegar mixed with oil. That's what helps with removing lice eggs from human hair, so I thought it might work for bot eggs too. Apparently the vinegar kills them and the oil makes it too slippery to stick around.

i put mineral oil on the legs and neck and chest area where mine usually get them. when it comes to scraping them off they are alot easier to get since they are sitting on the oil..

it saves me a huge amount of time grooming wise sometimes all i need is a rag and rub them off.

We have never had a single bot fly egg on a horse - could someone tell me if they are more uncommon in KY? What should I be watching out for, given something pops up?
