What I can't figure out is if these things are in my environment now or if me and my dogs are shedding them and if we are, are they stil infective? Would it be useful to do some sort of household treatment other than just diligent cleaning? My house is really clean. I'm sure my backyard is a parasite paradise though! I try to be good about cleaning up the dog poop but I'm not gonna lie, I'm not as good anot picking it up as I really should be.
