bananas
No literally bananas!
ok i'll explain......
ants LOVE BANANAS! make sure that the nana is slightly peeled with the phalic like tip exposed (ooh err missus)so that the little nippy buggers can get inside...
Place said nana near to where they are and the WHOLE nest of the fookers will come for the nana,may take a while so be patient....
Once adam and his amigos are snacking on the old nana then swiftly dispatch adam and his compadres with boiling water from the old kettle.
Once adamski has been dispatched or is in trouble,he secretes an enzyme thats informs the rest of said nippy buggers ans sends em into attack mode and they all come a running....
Swiftly dispatch rest of annoying fookers with boiling wasser.
If it dont work the first time then rinse and return,or try an apple but make sure the skin is off first!

THE VOICE OF REASON!
