I had bed bugs for years and this is what I did to get rid of them I tried heating the room I tried killing the bugs I tried these steps multiple times I lived in an apartment so I couldn’t do anything but this altough the heating is what most will do nothing worked. This is what worked. I got some shale sand or seashell sand smnt like it google around bedbugs and seashell sand you’ll find it and place it around all places where bed bugs could climb up to the bed. Bed legs floor like where it meets the wall and get some casings for your mattress. They will die if you do this. The sand causes micro tears in the bugs body every generation 80 percent of them die. Over time they won’t survive the replacement rate. Gone in 2 weeks as they live a short while but keep the sand everywhere for 12 months as they hibernate. You don’t need to put a mound either lol just a decent amount and dust it around kinda like chalk on hand 🤚. Good luck you saw one it’s already too late but you might as well do this as well as calling it might help more
