How many bad reviewists actually read the instructions before using total care spot on flea control????
It clearly states on the packaging that it DOES NOT KILL ADULT FLEAS.
It stops the eggs and larvae from developing into adult fleas so you need to combine this product with something to kill the adult fleas as well.
I use Capstar tablets to kill the adult fleas and then use the spot on to stop the eggs hatching and the larvae growing into adults. I also regularly vacuum the carpets to keep them down.
Once again for those in the back, this product DOES NOT KILL ADULT FLEAS.
It kills the eggs.
Read the damned instructions people.

I have 4 cats. i only use it on one of my cats as there is no way she will take anything orally. It works perfectly on her. I use capstar on the others especially my youngest girl. No spot on treatment of any kind works on her. Revolution, Frontline have been tried and she still gets has lots of fleas, oral medication is what I use on her and they seem to work. My kitten is using capstar also until he is a little older then I will try the spot on treatments.
inexpensive and works
Worried about giving it to my 8 week kitten after reading reviews
