Shake well before use. Patch test 48 hours prior to application if you have not used a D.E.E.T based product before or if horse is sensitive skinned. Spray evenly over the coat but be careful not to saturate. If horse or pony is nervous of sprays apply to a cloth or sponge and wipe over the areas required. For best results apply early in the morning before turnout and before heat of midday sun to allow the formula to dry and seal the hair. Avoid direct contact with mucous membranes. When fly infestation is very heavy, re-application may be required more frequently. Avoid contact with broken or irritated skin. Not recommended to use under saddles, fly rugs or fly masks as may cause irritation.
