No escapes for a while, but two serious problems have arisen for Sigyn and her Divas. The biggest issue is a huge grain mite infestation that I've posted about in other threads on here. I still have no clue how they got in there as I freeze all their feeders beforehand, but their whole outworld is crawling with mites now. They've spilled out onto my ant shelves and gotten in to other set ups, like my Formica argentea's dirt box as well.
In desperation, I ordered 12,500 Hypoaspis miles predatory mites from a seller on Amazon called NaturesGoodGuys for $19. If they work, it will be money well spent. I put several tablespoons of the mite-laden substrate in a plastic box I had and put this in their outworld. I'll keep this substrate moist for a few weeks, so they can proliferate and hopefully eliminate the grain mites. If they eliminate my prize colony as well, that won't be the first thing that's gone totally to hell in my life the past few months.
The second crisis may be related to the mites somehow because they have conquered the Fluon barrier in the desert outpost. I wonder if millions of dusty mites covering the Fluon is good way to ruin it? By the grace of God, the lid on there is containing them, but feeding them without escapes is going to be a real pain in the a** until I can clean and reapply Fluon. I won't be able to do that with my wife and kids around since it will be a real fiasco.
Keeping a massive Crematogaster cerasi colony is very, very difficult.
