I found bot fly eggs on my mares legs tonight when I was grooming her, or at least I'm assuming they were (I've never seen them before). They were tiny little yellow dots that wouldn't come off with a brush. She was trying to itch her legs a lot too. I scraped off the eggs with a pumice stone, and unfortunatly it made her bleed. I put wound dust on and an extra layer of fly spray and put her back in the field.
Is there a better way to get the eggs off? Is there any way to prevent the bot flies? What does a bot fly look like? What happens if I don't get the eggs off, or if I leave one behind?
I live in Maryland and I didn't even know that we had them. No one talks about them! I have a grey gelding and I've never seen them on him before (not that I've looked).
