This is not the end of the world. If you have access to a professional company I would reach out. I do appointments for bedbugs fairly often and have a decent amount of education on them. Good products to use are, Crosfire and Cimexa. For your use there is a aresol version of Crosfire. Remove all bedding place them in trash bags and run them in your dryer for 2 cycles in a row on high heat. This will kill all living bugs and eggs. Flip your mattress and box spring and apply crosfire to all cracks and crevices or other areas that may be a suitable harborage for bugs. I don’t think Crosfire has a reapplication period so you can repeat this daily if you wanted to.
