How to "privatise" the territory?

[RoffDaniel]

Hello everyone! Please tell me, is it possible to somehow privatise the undeveloped territory from the kusak? So that they do not appear, for example, in the illuminated territory. Or how does it work already in 2.0?

Thank you!

I had to google "factorio kusak" to figure out what you mean, it seems like it's how biters are called in Russian?

Well in that case, new biter nests are created by living biters; existing nests will sometimes create small groups that go to a location and create a bunch of new nests there. This is happening regardless of pollution, but there has to be a viable spot for a new nest nearby. To have an area where no new nests are created, you have to prevent those groups from entering it. So you need to wall it off and defend the wall. And of course you need to eradicate all biters within the walls too.

Alternatively, artillery will destroy all nests in a quite large radius. However, all biters from destroyed nests will rush to attack the artillery so your outposts need heavy defenses.

You don't necessarily need to build a full featured defensive wall to avoid biter nests being build nearer to your base. The groups that will build new nests will not settle near player buildings. So in the early game, if you loosely distribute cheap passive items like a belt, a pipe or a single wall piece near the nests, it can often act as a barrier the enemies will not cross. It's like a light fence, it's usually not crossed. But sometimes it is nevertheless. Don't put circles around nests, instead put a huge circle around your starting area with this light fence.

I found this a good (albeit time consuming) strategy to avoid many nests get into the original starting area.
It must be real items, no ghosts. And they must not be military buildings like turrets and radars, since these are attacked on sight.

I apologise, I completely forgot what they are called in English

Yes, "factorio kusak" is the name in Russian =)

Thank you so much for your replies! Actually, while I was waiting for them, I tried and tested on my own, and realised that biters appear in an area that isn't scanned by radar, for example. The situation I've got now is this: I have a peninsula. The part that goes to the land I walled with defence, the part around which the water is not fully screened. And what happened? That's right, the terrain that didn't wind through the map was quickly overrun with biters. ‘Build some kind of structure’ doesn't help anymore. I put radar, solar panel, battery and power line. Unfortunately, at night the power is not enough and the lumen is gone, they still appear there.... =(

This sounds like a bug (and the only good bug is a dead bug not encroaching on your territory, teleporting across walls, regardless of its radar state), have you got any save where this could be reproduced ?
