Got some finishing heifers showing signs of lice. What's the shortest withdrawal product to sort them out?

Further research suggests spot on at 17 days is as good as I'll find?

My experience with spot-on, has taught me that you might as well grow a pound per animal in the bin and spray the cattle with water.
When are they going for slaughter.

Will it matter if they’re going deadweight

Only if it starts to slow down their growth rates.Will it matter if they’re going deadweight
Started picking from them already.

Aren’t these statements slightly contradictory?

Thought that might be a response!
Well, no in that the first 2 sent were showing no signs, but several of the remaining animals are getting worse.

If they’re close to slaughter I’d shave them and let the air get to them

Didn't pig farmers usea a weak washing up liquid solution poured on the pigs back for lice? Probably cost a fortune for cattle.
linseed oil down the back or so they say but I have not tried it
I would say the same with spot on but I think dysect is better, maybe because it goes right alone the back

Pigs are a bit balder though, I am not sure that it works tbh.
I will be using the pour on wormer - but 28 days withdrawal and I wouldn't send any from a pen where I had used it even if they actually hadn't had the pour on themselves - potential to sort out worst and treat in another pen?

+1 for using a pour on wormer, seems to be the only one off treatment.
Spot on, Dysect, Swish all seem to need a follow up treatment a couple of weeks later due to them only killing what's there on the day and done cover the period after eggs that are already laid will hatch.
Every animal in the shed and preferably on the farm is best done on the same days if you are to have any chance with any if these inferior products.
