These are random, annoying and ridiculously bugged. They spawn in the base.... or most of the time with mine UNDER the base in the terrain. They make loud noise endlessly and are nearly impossible to kill because... they are under the ground AND you can't remove them with the Game Repair option because the game thinks that's where the spawn point is so they aren't affected by game repair at all.
Its really irritating and I don't know if the roache nymphs spawning near players sleeping position is intended behavior, and if it is its a really stupid mechanic and needs to be yeeted. Why would it even be a good game mechanic other than to irritate players and make them want to rage quit the game. Not to mention when the stupid thing does spawn in the base it is nearly impossible to get it out of the place without it damaging your stuff. Lost some spinning wheels and chests because one stubborn one wouldn't follow me out of my base, instead just attacking from where it was stuck in the chests. The one in the image below is likely killable because I can probably hit it from the rock, but it will likely damage the base some. I'm building right at the first ranger station by the food cart.
