Farnam Roll-on Fly Repellent for Horses, 2 oz, up to 7 days protection

This roll-on fly repellent for horses comes in a 2 fl oz (59 ml) bottle with a roller-ball applicator, and the liquid inside contains 0.40% pyrethrins. The manufacturer lists horses, ponies and dogs as suitable, and the roller ball is meant for placing the liquid around the nose, eyes, ears, mouth and wounds. On the label, the product is stated to repel house flies, stable flies, face flies and horn flies.

The bottle, the roller ball and the liquid inside

The roller-ball applicator carries the liquid form of the repellent onto the horse, so the product goes on where the ball is drawn across the coat rather than as a spray. The manufacturer lists pyrethrins at 0.40%, piperonyl butoxide technical at 1.00%, di-n-propyl isocinchomeronate at 1.00% and N-octyl bicycloheptene dicarboximide at 0.40% among the contents. The bottle holds 2 fl oz (59 ml), which is one pack of liquid.

The formula is stated to repel house flies, stable flies, face flies and horn flies, and the manufacturer gives the sensitive areas of the horse as the place for it. Item weight is listed at 51 g (1.8 oz), and the bottle measures 3.8 x 3.8 x 11.4 cm (1.5 x 1.5 x 4.5 in).

Where this roll-on suits a horse, pony or dog

The manufacturer lists horses, ponies and dogs, and the roller ball is intended for the nose, eyes, ears, mouth and wounds. A buyer should check that the animal in front of them is one of those three, because the label wording covers them and not other animals. The roller ball is the format for close work around the head and on broken skin, while the bottle's 2 fl oz (59 ml) is the full quantity in one pack.

What reviewers say about using the roller ball

Reviewers who mention the roller ball describe the application as easy. A smaller number of reviewers mention a pleasant smell or no noticeable odour, and two reviewers note that the protection does not last as long as they expected.
