I thought I'd researched the toxicity of cyanoacrylate glues (A.K.A "super glue") before using it in a formicarium build, but I believe I underestimated the 'gassing' period for the fumes to completely be eliminated and paid the price with the death of 30-35 ants overnight. From what I read (can't remember where but possibly in the forums here somewhere) the glue itself is not toxic, but the fumes being 'gassed' off while it dries is.
Now with that in mind (and to eliminate the fumes 'fogging' the acrylic in my nest) I actually had a huge fan going full blast as I used to glue. The irony was that the nest itself did not originally have any cyanoacrylate glue, but I decided to add walls to form smaller inner chambers in the large open space within the bead box I was using. The formicarium was actually used for a brief period last year but had some flaws that I decided to improve on so I took it out of commission until I could get the repairs I wanted and at that time decided the new smaller inner chambers could be added as well.

I believe my mistake was that after letting the glue dry overnight while the box was open and being aired out. I then closed the box for a few days and then hooked it up to one of my Camponotus Novaeborancis colonies. The next morning I noted a few dead ants but was not immediately alarmed thinking maybe the bodies were some that were already dead from their existing main nest (a bit harder to see in there) that they just brought out to this 'new space'. But as the day wore on and the bodies started pilling up it was clear that the new setup was to blame. I quickly configured a powdered tube that would have emerging ants drop into their outworld and by the end of the day the surviving ants had all evacuated that way. I'm not sure if some of those exposed have been fatally injured, but so far they look and act OK.

But now I am hesitant, especially as I have a second completely new formincarium that I made as an almost duplicate of the first in which I also added those same inner chamber with the cyanoacrylate glue.
Can anyone confirm that have successfully used well dried and cured cyanoacrylate and that it is OK?
