Preferred Etchant?

Well I wonder what our self appointed waste etchant expert will say about my disposal of spent ammonium persulphate, I simply let the water evaporate off which leaves a sludge then using a funnel with a thin hose on the waste goes down an ant hole. It does seem I need to do more etching as after I do the disposal the ants seem to move to another spot. In winter i have a bit of fun and put diesel down with a wick and the smoke comes up from another ant hole metres away.

I am sure forum members are sick and tired of our self appointed etchant expert and I reckon if we held a poll it would be 99.9% in favour of him shutting his trap on the subject.

Cheers Bryan
