There are a large number of ants making a trail from the ATF lab to the PSL lab.  They seem to be heading into a hole next to the lab door.  I just saw a queen ant poke its head out of the hole.  

Ants in the ATF lab are taking their ussual route along the AC conduit.  There are Terro baits laid ever 3-4 meters and they have almost emptied every one. The trails continue to the mechanical plant room accross the hall (room 259ME)

Laying down Terro ant poison now. Will buy more.
