We found fleas in our home on 11/13 (8 weeks ago) and I began treatment on my cats and dog right away and have been vacuuming every day since. I had an exterminator come about 4 weeks after we found the fleas and I am still seeing live ones. I have quarantined my cats to the basement. I only have carpet on my steps to the basement, which is where I am seeing most of them. My vet said I would need to vacuum for 3 months, but I feel like I will see a flea every day for the rest of my life. I need some advice on what to do and how long this may last.
