I'm not positive they are nesting yet, but they are in there in mass.
They are Odorous House Ants, tiny, black smell like mint when you squish them.
I edited out too much before lol. They are in the wall, as is obvious by the fact that they come in and out of some screw holes above the viv. I set up 4 of the liquid traps, put DE down, put double sided tape down, nothing is stopping them. Its been going on for a long time, but they use to be under control, there was only ever like 10-15 ants at any given time and they never bother the cham.
Now there is a lot, its not getting better, its getting worse. This is Compacted by the fact, that the Viv is made of a 2x2 skelton with 1/4 inch plywood on each side, is 4ft wide 6 feet tall, and 2 feet deep, with 48inch tall 25 inch wide 1/4 tempered glass doors and the walls are all lined with cork bark panels, it took an entire case (12 panels) to do that. The thing weighs, easily 300-400lbs. It takes 2 people to even slide it over a little bit from the wall, so "Move it away from the ants" is not possible.
Its way overkill for a panther anyway, so at this point I am looking at just complete demolition. I am building a reptile room, that this will take up too much space in anyway, so I been thinning about downsizing this cage, and sell this bare to someone with a bigger animal. Or keeping it for a living room showpiece for something that needs the space.
Also seeing their nesting habits on line, plus what they are doing in our home. This cage is built perfectly for them to nest in.... Its built like a house is framed, except it has 2x2s instead of 2x4s, and it has 1/4 plywood instead of drywall, same design prinicple though, the cork is then screwed in to place on the inner walls. Over engineered it, to the point where it is the perfect home for this ants...
