Monster nest achievement?

[a bad driver]

I recently completed the game and I'm considering NG+ but first, I want to get a few more achievements. I cleared out what I believed to be all nests in Novigrad/Velen but I did not get the achievement. I set the map to show ALL markers and there are no remaining monsters nests. I have also cleared all undiscovered locations just to be sure.

Is it possible that some caves I have not completed contain the remaining nests? I recall seeing the occasional nest in a couple caves but do those count towards the achievement? Any other ideas?

How many nests you have discovered on map ?
(It should give an number in map)

Also :

There are a total of 5 monster nests on The Skellige Isles. Destroying all of them unlocks the “Pest Control” trophy or achievement. 4 are on the main island (Ard Skellig) and 1 on the northern island (An Skellig)


Velen novigard has 28 nests.

I took this info from wiki page , Don't know if this is still accurate.

My map doesn't show any so at this point I'm not sure how many I have discovered. They apparently each disappeared from my map one by one as I cleared them (unlike the Places of Power which after discovering them, just grays them out but you can still see them on the map).

Since there are only 5 on Skellige (which also shows no remaining nests for me) I will just use a wiki to find them all and confirm they're cleared. Fingers crossed!

YESSSS! I got it! Thanks for suggesting the wiki. It was really easy to check Skellige because there are only the 5 nests as you said.

For anyone else wondering about this - I found that there was one nest in Skellige which I had previously cleared of monsters but I did NOT destroy the nest. I don't know if this is a bug or if it is working as intended but it definitely was NOT LISTED on my map. I assume my issue with Novigrad/Velen was exactly the same - being that it was my first playthrough, I likely forgot to destroy a few because I didn't know what I was doing.

For anyone wondering about Velen/Novigrad. If you have the DLC installed its 29 nests in total, including the new ones from Heart of Stone. Most interactive maps dont show that map part tho
