It's been my experience they help with ticks. But I have had no indication they help with fleas. The dang fleas are tough, especially this Summer. At least they are for me.

Last couple of years we been worming with Cydectin cattle wormer, either down the mouth or down the back (5cc)and we have not had a flea or tick problem . It's for internal and external parasites on cattle.it has done a good job for us on worms.

Do you sale the stuff Eastman Kennels

Yes we do .35 cents per cc's or I can get it in 500ml bottle for you. If you need more info call me at 985-773-3754

Mr Jim yall using the drench or pour on?

We use the pour on either down the mouth or down the back ( 5cc either way ). We have had good luck with it .
