Lice

Question
Hi there a few horses on our yard have lice and are being treated with spot on for cattle but they had to sign a disclaimer form before they could use it as it is not licensed for horses,my horses have been in contact with the horses mentioned but are not showing any signs what should i do?
    kind regards Gail

Answer
Hello Gail
Your horses are in high chance of catching it, if they have been in contact with the affected horses. I would treat them with what you are treating the other horses. Just use less of it. In case they do not have lice. Best to be on the safe side! Alright, good luck!
Thank you for the question
