It's that time of year again in Pasadena and the ants are going a bit crazy. There are about 10 on the floor in the ATF, and no doubt there will soon be about 1e6 of them. Do we have a standard ant removal scheme for cleanrooms? The stuff I use at home is a spray and probably not very nice for optics. We could use some of the slightly illegal ant chalk I guess.
Steve has the cleanroom janitor mop the 40m floor in the LVEA/IFO room with diluted ant poison.
