We use it also and have had no problems at all, besides them going crazy after I put it on
They are so silly! But we live in south FL and have never had ONE flea, so that's saying something. I like that it's all in one, and we don't have to try to get a heartworm med into them as well. I wish that we could go all organic and use the natural remedies that some on here have had great success with. I am not chancing an infestation because where we live it's horrible if one flea makes it into the house or onto your baby
