I decided to scan at five-second intervals to see what they were up to. Strangely, every time I scanned, more ants became active. The hell? I cut off the SUDDAR scans for a full minute. When I did another scan, about a quarter of the ants were inactive. Oh, hell. I stopped scanning for five minutes, then did a quick scan, with as low power as I could manage. Sure enough, most of the ants were inactive.
