So while moving things aruond all the ants retreated to the nest thus allowing my to take a cup and remove the sand and mix it with some soil from outside. I literally beat the dirt with a hammer and mixed in charcoal. Literally beat it with a hammer.... mixed it in with the sand and dumped it in. Found some pennywort growing in my backyard, ripped out and presto. Going to the store tomorrow for some moss and some kind of fern and mealworms.
The white sandy area in the top left is where ants are nesting currently.
Any advice on what to add?
The soil should be sanitized from outside. Worms are disgusting, though necessary.
