excessive rain

Fleas seem to be everywhere in my house right now and I need to do something right away. I don’t know if it’s due to the excessive rain we’ve had or the heat or maybe both. But right now I see them on the dog and in my carpet and furniture. I have looked at your site and I like the carpet granules but can I still spray on top of it to kill all the adults instead of using just the traps? Also, is it ok to spray the furniture or is there something else I should use on it?  I don’t want to ruin any of the fabric.
