ANTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

At first the kitchen was showing lil signs of em...
and then it became more obvious...more and more obvious....
an accident tumble of sweet liquid or even an unwashed plate of finished meal would get them there in just awhile..!

After that...and living room..(still ok coz not much activities there)..

and now...MY ROOM!!!.I'm typing with ants accompanying me on my keyboard ^^"...------....-,-''!!

We've tried several methods to counter the invasion..eg:patching up ant holes on walls...not putting sweet things on the dining table..and trying not to spill our drinks and also wipe off every excess tumble of the sweet liquids...

My question is..
The ants just wont stop coming...
Is there any methods to counter them?
If the situation gets worse...can call those pesticide service dudes ah?

thanks alot!

What is cni ah..?but if use insecticide aerosol..means the whole kitchen must be cleared lo..??

electronic devices really lurks ants ah?
