I Have a Question

Is it possible im finally getting rid of these bugs? my apt building has had issues with bedbugs. Ive had to have my place heat treated and sprayed several times. Ive had to get this company to take my bed away, after that i was sleeping on the couch but a month ago they told me i had to get rid of that too cause the spraying wasnt working and the bugs werent leaving. so i got rid of it, i was thinking of doing that anyways. after the company picked up my couch, i couldnt just leave it by the dumpster , didnt want someone to take it home with them so i went to walmart after and got me an airbed, got that on purpose cause theres no where for them to nest , i saw a couple of stragglers after that and killed those, and now almost 3 wks later i havent seen them since. do you think they just dont like my new bed? any possibility of them being gone for good? pest control comes by once a month to deal with all this
