Permethrin is actually a more appropriate pesticide for bedbugs but unfortunately they are mostly resistant in the US at least. I have found literally 'baking' a room to 120F + for 30+ mins is the most effective way to eradicate bedbugs. Amazon search (360 propane heater), and don't die of CO poisoning or burn your place down. For a more tempered approach, you can try setting up 'safe zones' with boundaries of double-sided sticky tape, smeared vaseline, or diatomaceous earth. (you can kinda tell they've co-evolved with us ey!).
