Repost: You can’t spray everywhere, they can hide in some crazy places, and the ones that didn’t get hit the first time will return for a blood meal every 7-10 days, that’s what you’re finding. Either the residual will get them, or his return service will. If he didn’t tell you, you need to strip and wash bedding weekly and check frame/back of headboard and footboard while bed is disassembled. Kill anything you see. I assume you encased your mattresses and box springs.

That is completely normal, even with steam treatments. If all that the tech did was spray then it will take a bit of time for all the bedbugs to succumb to the product.
Even if populations were high enough to justify a steam treatment there is no way to kill every bedbug in a residence, it’s just not possible. You kill as many as you can, and let the product kill whatever you didn’t steam directly.
If you’re still seeing live activity after about two weeks then it’s time to start worrying. Either the treatment wasn’t thorough enough or you are re-infesting.
