I am switching my dogs flea meds around to a bigger strength of k9 advantix 2 and want to get a spray that I can spray around my house to get rid of any fleas/ticks/other pests. Something that is safe to use for me and my dog. Aka not one that I have to leave the house after use or that I would have to remove my dog from the area to spray. Anyone have anything that they have tried that got rid of these pests? I have heard of one called wondercide I think that is supposed to be good. What does everyone use?
