Carpenter ants.
DE or Diatomaceous Earth. You can get the food grade, non toxic, they have an accordion like thing on amazon too (pest pistol) to spread it with (definitely wear a mask, it's not poison but you don't want to inhale it).
DE is a drying agent, basically they get coated with the dust and will wither and die. Go along the baseboards and the base of the foundation if you can.
This crap works on spiders, millipedes, and centipedes too.
Unfortunately it does diddly squat to asian stinkbugs.
