good luck then, that didn't work for us at all as the fleas did not jump onto our dog in mass but instead bit on us and layed eggs all in the carpet and couch. The young ones live off of fecal matter form the old ones so they come out in waves. it took forever to get rid of them. Multiple bombings and draino in the tub from when we gave the dog a bath and he has fleas. They are stubborn little tirds
