Maybe a cattle oiler with pyrethrin/permethrin would do it for you? My cows have some lice, especially on the calves if they get a bad case I'll douse a sponge with Ultrashield and rub them down with it, knocks them out pretty good

Is this correct that Cydectin does not work on lice?
Kenny 10-12 years ago here we would pour the dairy cows about time it started to warm up. Them cows would quit itching that day and 3-4 days would have all their winter hair gone and be shiny like the day they were born.

Doesn't seem to have any effect on lice here, but 15+ years of using it maybe has something to do with it?!

Boss works well, Cylence works really good. I used up some leftover generic Sabre I had for fly control here last Saturday. I'll find out soon if it works!

I don't pour anything. Everything I use is injectable.

There are two different lice - biting and sucking. I believe Ivermectin does NOT kill sucking lice.

Ivermectin pour-on kills lice, both biting and sucking (assuming the lice are not resistant). The following list comes from the manufacturer's brochure for Ivomec Pour-on:

roundworms
lungworms
grubs
mange mites
horn flies (for up to 28 days!)
biting and sucking lice

Diogenes.

Wasn't sure. Thanks. Some kill one and not the other.

It needs to be duly noted that Merial's injectable Ivomec & Ivomec Plus clearly states the product specifically kills sucking lice. No mention is made regarding its efficacy regarding biting lice.

We poured the bulls and bred heifers with Vetolice yesterday. The cows will be getting a scratcher and backrubber tomorrow.

Please let me know how it works.

We used Noromectin last year, used it again for free on part of the herd. Used Boss when we gave scour shots. Should have done it earlier as the calves showed being lousy this fall. Boss did clean up the bull herd.
Vaccinations, cheaper than whiskey. ;-)

Aaron wrote:What product where you using Randi? This year I used AVL as that was what was in stock at feed store - if I see any issues I will go back to Ivomec. Normally use Noromectin or Ivomec. I only use ivermectin for the sole purpose of killing lice. Fecal samples tell me almost zero internal parasites before application. But lice in January and February is what I always aim to avoid, otherwise I will find cows scratching with 4 legs in the air. The cheap Vet-O-Lice, etc. products where you need more than one application over a 2 week period, do not work for me.


Aaron, it is the AVL stuff that we used this year. I was a different brand last year, and I'm not sure which one it was.
