These ants apparently didn't think we were very good tunnel builders. They have filled in most of the starter tunnels we made and constructed their own. They have even used a slivered almond as a roof to the main entrance. This happened all in one night.
This is the view of the almond roof from the outside.
So what happens now? how long will the ants live, are there any females to continue life?
They will live for several weeks, but alas, there is no queen. It is a colony of bachelors.
