LICE WAR. Please Help!

PLEASE HELP! Our horses are in optimum health, excellent living conditions, and fed and groomed regularly. We have no birds/chickens or other lice carrying animals.

But we've been having trouble with sucking lice in our horses all winter. We've been treating them with Ivermectin regularly; it works great, but the lice are back in full force within the next month, and the horses are back to itching their fur off and scratching all the time. Ivermectin has worked far better than the powder so far. But the infestation is persistant, refusing to be totally killed off. It's like a host of eggs stick around just to hatch out again 30 days later!

Frequent treatments just seem to be a waste of time, nothing more than a deterrant to the little monsters. What I'm wondering is wheather or not the Lice will go away when they shed their winter coats. Will the summer heat and sleek horse coats drive away the villains? Does anyone have any previous experience with this? Will they be easier to EXTERMINATE when summer comes around?

Thank you!!!

Sprinkle FOOD GRADE DE around their stalls and other areas where they lay down.

Make sure it is FOOD GRADE.

Horses with healthy skin do not get lice or rain rot.

Add Vitamin A to his diet, either in a supplement or by adding a good loose mineral that has at least 200,000 units per pound in it.

In the mean time, you can dust him with Sevin Dust. I used to get 10% SEvin, but I have been told you can only get 5 or 8% now. Put it in an old sock and pat him all over with it getting im particularly well in the base of the mane and on his top-line. It also works very well in the spring and summer for ticks.

Bu the way, this is the time of year (just before green grass) when lice are the worst. Most horses stored Vitamin A is depleted by now so they are very prone to rain rot and lice.

You can 'jump-start' the Vitamin A by give a horse 5 cc of injectable Vitamin A orally in the horse's mouth. You do not have to give a shot,; just squirt it in their mouth about once a week until the Vitamin A added to their diet can kick in. Works every time
