I've been looking all over the web and I'm have some questions on delousing horses... more of a want to know more than an immediate concern.
I've found the Ontario Ministry of Agriculture's info and it looks easy enough, but the products they list for treating Lice are not products that I have been able to find easily.
My horse is part of a herd enviroment that extends into the bushline and I've noticed that he's starting to itch a little more than normal. Now they are starting to shed out, plus they were due for deworming - which has been done - but I'm wondering if there's any harm in delousing him too, just to be on the safe side.
I know it's possible to get lice from wild animals, and I also understand that my treating just him is probably a mute idea because if lice is in the herd, then the whole herd would have to be treated plus all the tack for 30-some horses. But I still want to do my best to help my horse out.
I'd be looking at treating for the "chewing louse" and they keep mentioning powders and shampoos as being effective. I'm a little loathe to shampoo right now, as while the weather is warmer, it still drops below freezing at night and we don't have access to a heated barn, nor warm water right now. Powders sound like a good idea, but I'm not sure which
powders would be the most effective. One article I read suggested putting mayonaise on the horse... I can't picture that going over well at all.
So to summarize, my questions are basically this:
- Is it harmful to delouse the horse even if he may not have lice?
- What products are best to use for delousing, and where are the purchased from?
