Comfortis CAN be given with some other flea medications, just like some people have to take two blood pressure meds, etc. Your vet should know of any interactions (e.g. spinosad and high dose ivermectin).

Now that is not to say this is optimal long term. It, however, may he necessary short term. Consider the flea and tick combination products. It is no different.

If you still see fleas in your carpet, then you probably have hundreds more (and thousands more eggs). If you are still seeing any and have been unsuccessful at treating your floors then call an exterminator. Do not use cheap flea bombs and wait for some magic to happen. First, it probably won't work. Second, you will have chemical alll over the place in prime locations for dogs and choldren to be pousoned.
