Active Ingredient(s): Cypermethrin (as Cypermethrin pyrethroid)
Dosage:
Flectron eartags can control flies for up to 4 months when used as directed. For maximum benefit they should therefore be applied at the beginning of the season before fly populations build up. For complete control the entire herd should be tagged. One tag per animal is usually sufficient to achieve acceptable levels of fly control. However, where head and face fly attack is very severe, two tags may be necessary, one on each ear.
Withdrawal:
Meat and offal: Zero days.
Milk: Zero hours.
Tags should be removed before cattle leave the farm for slaughter
