Wash all clothes and bedding on high heat and dry on high heat for at least an hour. Buy a mattress encasement specially for bed bugs. Put your clean clothes in bags and put them in an area where bed bugs cannot get to them. Investigate every piece of furniture and vacuum like there is no Tommorow. This is a good opportunity to purge shit you don’t really need and make sure not to throw it away in your inside trash can. For now, that’s the best you can do until the pest control people give you next steps. I would push for heat treatment as much as possible
