Infestation Containment
- Bugs will actively try to attack you if you get too close. Even if
there's a wall in between they sometimes will try tunneling towards you. - If you attack the hives they will try to get back to the hives to defend them.
- Yes, they might at some point try to attack more things, although if it's far away from them they might just be content to wonder around.
- Yes they sleep, usually during the regular day night cycle. It's safe to approach them and rescue colonists, as long as you don't walk into a tile next to them.
It's also safe to build a wall around them, fill the space they are inside with wooden floors and wooden chairs, add a few incendiary traps and then watch the chaos unfold once they wake up.
Be careful though, bugs will tunnel trough two doors to get away from fire before the succumb to the heat, make sure there's lots of layers so they can't get away once the fire start.
