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.
