@pumiquxt@sfba.social Probably not bugs then in your case. I'm not a fan of the ionization detectors as they can be really slow to react in slow burning fires. What I've found works well in our house is a model that has both a ionization and a photoelectric detector. No false alarms yet, and it has gone off at exactly the right time when my wife seasons the cast iron cookware. I'm a retired fire inspector so I spent a lot of time talking to people about smoke alarms, what causes false alarms, and how to mitigate them.
