Crovect & rain

[twizzel]

Just done all my ewes with Crovect for lice, so pinstripe down the back. Pulled out a couple of culls, let them stand in for an hour whilst I fluked and mineral drenched the others. Then put the culls out and the heavens opened the rest of the ewes are still in the shed but how long do they need to stand in before they can go back out again? Thanks

Had lambs with lice once and heavens opened half an hour after they were treated (outside). Seemed to clean them up without further treatment but no idea how much it would affect persistence.

Thanks. Had to turf them out in the end but they’ve had 6 dry hours and hopefully a dry night ahead...
