An animal collar includes an elongate tubular member of open mesh material having devices at its ends for securing the collar around the neck of an animal, and a pesticide member positioned within the elongate hollow member. At least one of the openings of the mesh material is enlargeable from a relaxed condition in which the pesticide member is too small to pass to an enlarged condition in which the pesticide member can be inserted or removed.
