  1. 2.0 out of 5 stars

    "Not Great"

    These tags have now been on my cattle for three weeks and their effectiveness is not good. While face flies are fairly well controlled, horn flies are not. I will be ordering another type of tag and replacing these on my cattle. Disappointed.

  2. 3.0 out of 5 stars


    These tags are a little more difficult than some to apply because of the shape. They also took a full week to really take effect on the horn flys. We will see how long they last and I might up the number of stars.
