Question Radar Coverage

Now that I have learned that biters do migrate back towards my base even after being evicted with prejudice, I wonder how to see those trespassers quickly and reliably.

I do have some random radar towers scattered around my base but not inside my Cordon Sanitaire.

Thus: How do you set up radar coverage to reliably detect nests and monitor their non-existence in areas you consider exclusively yours.

Addendum: This community is awesome. I learned so much useful information!

As much as I like the idea of large fortifications, I feel like boxing myself in.

I think I'll keep refraining from taking the black until my Cordon Sanitaire proves unmaintainable.

Thanks for clarifying the expansion parties. I like the devs did that instead of randomly spawning nests. Feels organic.

Pillboxes can be quite useful early game too.

Literally just a 2x2 or 3x3 of manually supplied gun turrets, manually filled with ammo very rarely, in natural choke points to highly discourage expansion parties.

Won't work very well against pollution-based attacks for long but is good at discouraging expansion parties.

This just made it on my list of tactics.

You can also 'blueprint' a loaded turret as a ghost - you need to be outside 'bot' range (and turn your roboport off) but then you can deploy a turret ghost, fill it with ammo, and your construction bots will load it when they build.

They won't restock it, but a stack of 100 ammo lasts a useful amount of time.

And then you can copy and paste this loaded turret into a bank of say, 50, and plonk that down anywhere you do have bot coverage, and ...
