OregonBR - 2014-11-18 11:29 AM I was just reading something about this a few weeks ago. Â The eggs that are laid on the horses hair hatch within 2 weeks of being laid. If they happen to get ingested then the wormer can kill them. After 2 weeks they are no longer a threat.
Ivermectin and Moxidectin are the only 2 wormers that can get bots. They not only get them in the stomach but can get them in the migration stage. The best time to de-worm for bots is in the winter months when they are actually inside the horse. Â The recommendation is to time de-worming for after the first frost (or after bots aren't around anymore), and in the early spring (before the bots pass out to continue their lifecycle). Â Â 
I have asked veterinarians this question for years and no one had an answer. My question still is if you see a yellow (egg) or whatever you call it on their leg then does that mean if the horse licks it will it go to their digestive system. I am so anal about the eggs I scrape them off every day if I have to. I have seen pictures and real intestines also where worms have been attached and I can't stand the thought of my horses stomach looking like that. I know, silly me.Â
the larvae is inside the yellow egg, once the horse licks it and it feels the warmth it starts to come out and then gets ingested but the yellow egg will remain on the horse. So even after you worm and there are yellow eggs on the horse, doesn't necessarily mean that they are infected with bots. That's why they say wiping with a warm rag will get rid of them but you are still left with the lovely yellow dots! |

I just read that it says that the larvae will "CRAWL" to the mouth... I did not know this... I thought it was all about the horse licking the yellow eggs... things that make you go HMMMM |

I think it has to be really close to the mouth to actually crawl to it. I was thinking that the horse licks it or rubs on it and it gets on the muzzle and then crawls the rest of the way in.  |

  Location: The South | I'll add another question...has anyone ever heard/read that spraying fly spray on them kills the larvae? My dad told me this and my first thought was "whatever", but now I'm wondering?
We have more on the horses now than we've ever had, I need to start scraping a little each day so it's not so overwhelming. |

I think it would, maybe depends on the type of insecticide you spry though... |

   Location: Arkansas | If the fly spray has an insect growth regulator (IGR) it will kill the eggs. |

| I would like to know the actual FACTS about bot eggs. We were taught that it was the warmth and moisture of being licked that caused them to hatch. Just read an article a few months ago that stated that it the carbon dioxide breathed out by the horse when licking/scratching that actually causes them to hatch and to be careful when removing them as if you get too close and breathe on them, they can hatch AND YOU can get infected (something I have always wondered about).
I am anal about them and about had them eradicated before the Amish moved within a half mile.......sigh. I usually just pick them off one by one, holding the picked eggs in my hand so they do not fall to the ground and are able to be picked up by a grazing horse. I really HATE it when the retarded ones lay bazillions of eggs in their mane!!!!!After the first hard freeze and all chances of more eggs are gone, I worm with a boticide.
What I really want to know is the BEST time to worm after exposure. I think that article said two weeks after exposure. If wormed too soon, the larvae are not mature enough for the wormer to be effective. |

| I'm with Komet, the grill scraper or shedding block is what I find to be the easiest way to get rid of them. This is the worst year we have had for bot bees in a long time. |

      Location: Texas | I use a Slick'n Easy block which is just like the grill blocks mentioned. My kids used to call the fart blocks because they stink :) I always use Zimectrin after Christmas to treat for any bots I missed. It's always worked here. |
