It looks like the provided search results didn't contain the specific steps, but no worries! Dealing with fleas on a couch is a common problem, and I can certainly walk you through how to handle it.
First, you'll want to do a very thorough vacuuming of the entire couch. Remove all the cushions and use the crevice tool to get deep into all the cracks, seams, and corners where flea eggs and larvae love to hide. Vacuum the cushions on all sides and the main frame of the couch. Once you're done, immediately seal the vacuum bag in a plastic bag and throw it away in an outside trash can to prevent the fleas from escaping back into your home.
Next, if any parts of your couch have removable covers, like the cushion covers or any throw pillows, strip them off and wash them in the hottest water the fabric can safely handle. Drying them on high heat will also help kill any remaining fleas or eggs.
For the couch itself, you have a couple of options. Using a steam cleaner is a great chemical-free method, as the high heat and steam can kill fleas at all stages of their life cycle. If you don't have a steam cleaner, you can use a flea spray specifically designed for furniture and upholstery. Just be sure to read the label carefully, follow the instructions, and test it on a small, hidden spot first to make sure it doesn't discolor the fabric.
Finally, remember that if you have fleas on your couch, they are likely elsewhere in your home and on your pets. It's crucial to treat your pets with a veterinarian-approved flea treatment and to clean the rest of your home, especially carpets and pet bedding, to fully break the flea life cycle and prevent them from coming back.
