Zero fumes means no evacuation needed.
Guys, speaking from experience I swear, I got Super Gel based on the reviews but literally from the first day I started praying for it the cockroaches started crawling in the house of course I put it under all the doors and in kitchen corners and any place they multiply literally literally literally it's worth every riyal and after three days I go back and put more and after a period I go back and put more the important thing is don't let your house be without it
