What I would suggest is to treat your dogs and cats ( if any ) and then vacuum , vacuum , vacuum and vacuum again , no powders needed . But remember to empty the bin or toss out the bag EVERYTIME YOU VACUUM because if you don't , those darn buggers will just climb right out and deposit themselves into your rugs again.
After about a dozen or so vacuums , you will be free of them

We never suggest using any kind of flea treatment powders on rugs , they can cause more harm then good , so please don't use them. Be vigilant about vacuuming and you should be fine. But you MUST treat your animals FIRST ! I prefer ADVANTIX over any other product. I find it works so much better then Frontline ever did. I used Frontline many years back and it never worked completely . But ever since using Advantix , I never had a problem with ticks , fleas , mosquitos ...
If you don't want to use this product through the winter , you can always switch to a heart worm medication that also provides flea protection like Sentinal once a month treatment.
I use the Advantix right through the winter months if we don't have any consecutive days of below 32 degrees because if it stays warmer then that , fleas continue to live and thrive. Below freezing for 4-5 days , those buggers die off.
I would never use any product on my dogs beds , my rugs , or anything else. By doing this you could possibly make things a whole lot worse for the both of you.
Imagine being at their level and breathing in those products for 24 hours a day for days !!
Not a good thing , and they can cause allergic reactions too. No product is safe because they are made to kill something , so use caution when using and apply them.
It may not be as bad s you think either , your dog could have picked up a hitchhiker from the park or woods and carried them in the house , so don't worry , there is a light at the end of the tunnel , just be prepared to be very friendly with your vacuum for a while

Good luck !.
