Left my soil outside

Well I left my soil outside. Well I got it over a flyscreen and 100 what candescent light bulb. Do you think it will kill the bugs in my soil. I only seen 2 bugs an earwig and worm the eawig. It killed the earwig and 5 minutes later it killed the worm (nightcrawler). Do you think it will kill the rest of them? Well if there is any. Good thing I sift my potting and and mix it 50/50 sifted and unsifted.
