Pharmachem Shield is a ready-to-use insecticidal pour-on for horses which aids in the control of synthetic pyrethroid susceptible nuisance flies, biting insects, and Queensland Itch on horses. The pour-on action is easy to use and lasts longer than sprays. Treatment for nuisance flies should be applied every 6 weeks or as required depending on insect pressure.
For the control of Queensland Itch, treatment should start at the beginning of the season by applying once weekly (or more frequently as required).
Shield controls the following biting insects:
- domestic and bush flies
- stable fly
- biting midges
- buffalo fly
Shield may be influenced by rain and activities such as rugging, brushing or washing. For best results, allow 12-24 hours for Shield to dry before exposing your horse to these activities.
