Our Safari Flea Comb effectively removes fleas and debris and detects skin problems in early stages. Before using, groom your pet with a Safari comb or brush to remove mats and tangles that could damage the teeth of the flea comb. If needed, apply flea treatment before combing. Comb your pet slowly, periodically checking the teeth of the comb for fleas or debris. Pay particular attention to areas around the ears, nape of neck and base of tail. Between strokes, dip the flea comb in a cup of water with mild detergent to kill the fleas left on the comb.
