I use this on my kitties and it allows me to rest easy each summer. I don't see the need to have the treatments during the winter.

I swear by this stuff. It is a tad expensive, but I hate fleas. I cannot believe you have escaped having to do this before now.

There are cheaper versions on the flea treatment and I have never tried them.

I, too, recommend you put flea powder in your vacuum cleaner(s) for the next few weeks. Depending on the infestation, you may need to bomb the house. Sounds as though the fleas have decided to call it home.

I drove myself crazy trying to control fleas, for years, until I caught on to the monthly treatments directly on to the cats. Works like a charm.

If you keep all your kittens inside, it isn't usually a problem.

Good luck. We have all been there!
