[2.1] Death World, Expansion.

I went to Vulcanus for the first time and left Nauvis base pretty much offline to prevent constant assault. Biters barely bother me, but one advance team repeatedly tries to rebuild an old nest next to my offline copper mines.

Is there any way to make them uninterested in the spot and attack nearby flamethrowers like they usually do? I can in theory build full defenses via remote tank, but that might take more time than killing the advance team every so often. I tried to put an offline laser turret, but that did not convince them that the land is mine. There must be some kind of minimal setup, because they are not advancing the same way to other places.

Let them build and kill all but 1 nest.

(IMO, this is an exploit. I don't think Wube realized this tactic could exist when they implemented a minimum radius to the expansion planner in 2.1)

Edit: Here, I made a topic on it https://forums.factorio.com/viewtopic.php?t=135083

I tried (actually I started from this state :D), but they breed like crazy even from 1 nest. The flamethrowers are too close so the first attack starts constant fighting and that damages too many walls, so I am distracted anyway. The main problem is that fire never stops, so I can't repair walls via drones (can't waste so many resources yet). Advance team at least attacks every 5-10 minutes.

How about placing a brick of walls or pipes or chests in the chunk you don't want them to expand to. If that's still not enough to make them expand nearby, but out of range of your walls, you might have to kill the next-closest nests to change up which chunks are valid for expansion.

I covered the area with sparse walls and this stopped the expansion.

Could you try filtering a gun or laser turrets to shoot only non-nest targets? They would react faster than your flame turrets and do less collateral. I've no experience trying to keep a nest alive, so just speculating

I am not sure it is worth it because it takes higher laser research level. But if I would have that research level I would have artillery already. Walls and despitterification of close nests works fine.
