Hello there! Dealing with bed bugs on a sofa is a really tough situation, but you can definitely take steps to handle it. The provided search results didn't offer specific content to draw from, so here is some general guidance from an expert perspective.
First, you'll want to do a thorough cleaning. Start by vacuuming every single inch of the sofa. Use a crevice tool to get deep into the seams, tufts, under the cushions, and along the frame. Once you're done, immediately remove the vacuum bag, seal it in a plastic bag, and throw it away in an outdoor trash can to prevent the bugs from escaping.
Heat is one of the most effective ways to kill bed bugs. If you have a steamer, you can use it to treat the sofa. The steam needs to reach a temperature of at least 130°F (55°C) to be effective. Go over all surfaces slowly, allowing the heat to penetrate deep into the fabric and stuffing where bugs and their eggs might be hiding. Be careful not to make the sofa overly wet.
For a more targeted approach, you can use insecticides specifically labeled for bed bugs and for use on upholstered furniture. Always read and follow the directions on the product label for safety. Another option is using a desiccant dust like silica gel or diatomaceous earth. You can apply a very light layer of this dust into the sofa's deep crevices and voids. These dusts work by destroying the bug's outer layer, causing them to dehydrate.
Keep in mind that sofas are very difficult to treat completely because of their many hiding spots. If you've tried these methods and still see signs of bed bugs, your best bet is to call a professional pest control company. They have the experience and access to specialized treatments that can fully eliminate the infestation for good.
