Deosect 5% contains cypermethrin. It is diluted and applied topically to horses up to every two weeks to effectively control flies and lice. Deosect 5% should be applied throughout the fly season monthly, increasing to every two weeks in horses with lice and those in contact with them as necessary.
Just 10ml of Deosect diluted with 500ml of water is enough to treat a 500kg horse. It can then be applied with a sponge, hand sprayer or knapsack sprayer.
To control flies, Deosect should be applied at the start of the fly season & repeated monthly. For severe head & face fly control, it can be applied every two weeks.
To control lice, Deosect should be applied when they are noticed & doses repeated as neccesary with a minimal interval of 14 days.
