The fact that lufenuron does not kill fleas is what makes it a safer product than other flea medications– because it’s not a pesticide, like the others are. If you do not have a serious flea problem, you will notice it working within a couple weeks, as the existing fleas and eggs go through their life cycles, coupled of course, with regular bathing, flea combing and vaccuuming.
