Not many bugs go dormant out here thanks to the weather but because of that nature here moves quickly.
Are you buying from ohana greenhouse by chance? Some years ago i used to buy ocean forrest & RO b2 from them, 90% of the time the bags had fungus gnats and sometimes soil mites. No big deal, they will die down with a good wet/dry cycle & some yellow sticky traps.
Ime, gifted/bought outdoor clones are even worse than bringing your own outdoor plants in because they likely came from a cannabis thriving area.
