Hi everyone,
I am trying to figure out if I need to put grout in some of my acrylic nests or not. I know that Camponotus pennsylvanicus produces formic acid and will need a substrate, but do any others? I've only come across and have Tetramorium, Lasius, and Prenolepis imparis.
I would just throw grout in these new nest, but they are vertical and would be tricky to do so. So if I don't have to add grout, I won't.
Thanks
