Ivermectin poisoning

[casportpony]

I gotta ask, are you sure you're seeing mites and not lice? Ivermectin will_not_treat any type poultry lice that I know of. And I agree with what Dawg said about over use and it's efficacy on mites, that certainly is possible.

Switching out product classes is always a good idea. However, topical admin. of avermectins (ivermectin/eprinomectin/etc) will kill adult biting & chewing lice that aren't resistant (read a patent app. for an ivermectin based shampoo for human head/pubic lice, recently).

Initial tests on ivermectin were performed with injectables on cattle & sheep, which might have caused some confusion.

vermectin and abamectin belong to a newer group of potent antiparasitic agents and fermentation products from Streptomyces avermitilis (Burg and Stapley, 1989). These systemic compounds are relatively persistent, broad spectrum toxicants active against nematodes, acarines and insects. Different formulations of ivermectin that can be applied by injection, orally and topically are available, and the type of formulation can have a marked effect on the antiparasitic activity. In general, the injectable formulation exhibits the highest activity against many species of ectoparasites. However, biting lice such as B. (Damallnia) bovis (Figure2) and B. ovis from cattle and sheep, respectively, are not eliminated consistently from animals given therapeutic injection or oral administration of ivermectin, whereas sucking lice that ingest blood body fluids from their host are highly susceptible (Benz el al. 1989). This difference may be related to the superficial feeding pattern of biting lice since when ivermectin is applied topically to cattle it effectively controls several ectoparasites (Barth etal., 1986; Alva-Valdes et al., 1986; Hotson et al., 1985) including sucking and biting lice..

In cattle?

Adult lice are killed with a variety of pour-on products available at your feed store. Injectable ivermectin enters the blood stream and will kill the sucking lice. However, biting lice do not ingest enough blood to be killed. If biting lice are present, a pour-on ivermectin product should be used. Many of the products do not kill lice eggs and a second treatment needs to be administered two weeks later as the eggs hatch. Dipping and/or spraying with an approved compound with applications two weeks apart should effectively eradicate lice.

"Ivermectin wont kill lice. Poultry lice feed on the feathers, dander and dry skin. Their fluid intake is from the eyes and vent. Sevin dust is way more effective applied once and repeated two weeks later." Quote from Pine Grove 11/19/11.

Maybe I could get someone to send me some pour-on ivermectin so I could see for myself? I'd go buy a bottle, but it's just too expense, lol. I know for a fact that oral and injectable ivermectin do not treat poultry lice. I wonder if I used 1% topically if that would work? Maybe I'll find a mean ole rooster and try it.

Or maybe I could pick some off of a chicken, put them in a dish and add ivermectin?

Thought I should add that a horse of mine had lice and one dose of *oral* ivermectin at .2mg/kg did the job. Lice on horses can cause anemia according to what I read, so I guess that means they bite, lol.

They would drown.

Quote: I was just thinking that, so what if I put them on a paper towel soaked in it? Heck, I have a whole bottle of the worthless stuff, lol.

Yes, horse lice are a different type of lice than poultry lice. Much like worms, horse nematodes wont infect poultry and visa-versa.

Seriously, I would like to get my hands on a few cc's of the pour-on. There's a guy at TSC that has cattle, maybe he can give me some.
