We are being taking over by Fleas! I can't take it anymore.

My little spike is just covered no matter what I do. I use to use the Frontline Plus. Switched over to K9 cause my friend said was good for the mosquito's.
NOT! It doesnt last more than a couple days and they are back - all over. I have an older Lab outside that I treat as well. We have fleabombed the garage where shultz (lab) sleeps and have sprayed the yard- but yet my spike just rolled over on the deck and there where like 25 fleas just on his belly - WHAT THE HECK!

Maybe the answer is going back to Frontline Plus. What do you use on your Yorkie???
I am so angry tho because I bought a 4m Supply for both dogs and the stuff is not even working grrrrrrrrrrrrrrr
Thanks for your help in advance!
