Alternative to flea drops?

NEVER use Hartz! also you can use dawn dish soap...the blue kind, it kills fleas, just let it sit on him from the neck down for 5 min and while its sitting use a flea comb on his face to get any that might be there...it is not as effective as say frontline or advantage but it will kill the fleas that are on him...but not what is in your house already like frontline and advantage will...the shampoo will only work for what is only him but if he has fleas the you will have eggs and more fleas in your carpet and couch and the shampoo will not kill those, i would say try frontline plus(ask your vet first) it is a drop but he may not have the same reaction since it is higher quality then sentry, and it will kill any fleas and eggs that end up on him which will be any flea in the house!
