Should I just sterilize the water for the buffers? Or should I make the buffers and sterilize them? Will that damage the buffers? Thanks.

Mind you these are the larger black ants. I killed two and then got distracted and forgot to clean them up. A couple of minutes later I noticed there were two more ants carrying off the dead bodies.
