Is orkin effective against fleas?
My home is about 2000 sq ft....it has about 11 rooms. We've tried the vet sprays and vacuuming for almost a month now. Fleas have bit my 2yr old son, but my wife and I have never been bitten. We have one cat in the house. We've tried several different flea sprays and are keeping the cat on Frontline plus. We are about to have a nervous breakdown. We can't go through the process of moving all the furniture and treating all the floors and furniture and washing everything again. I'm calling Orkin in the morning, but I wanted to hear other people's experiences and suggestions about Orkin. I appreciate anytime you would give in answering. I hope that none of you have to go through this experience. Thanks.
Ask if they have a guarantee.

You need to be doing daily vacuuming to be effective on the loose fleas in the house. And get a dehumidifier, the eggs wont hatch if the air is too dry. Your cat's Frontline will kill the ones that get on her--eventually the fleas all will die that way.
