Are you talking about Front line Wynette? I would like to try something different also. If you come across any dosage let me know please. I had a family of Wrens nesting in a blue bird house very close to my coop well yesterday the babies fledged so today i climb the ladder opened the door expecting to be covered in mites, nope not a one. Did go ahead and spray the house out though.
I've read frontline as used by some. I think I found that by doing a search for dosage of ivermectin pour on.
