The little brown ants that like electrical equipment are 'Ginger ants' they are attracted to the hum of the 50-60 hertz vibration , these are a real pest in the NT as they get into every thing electric to nest , on that if anyone is interested ,,,
There has been a study done in the NT and some smart cookie worked out that there is 20 TONNS! of ants in every sq kilometre of the NT ! ,,
that's a lot of ants .
