ants

planted a large lily that was given to me by my mum. seems that it housed a huge colony of ants.
i dont mind them in my garden, but i squashed 7-8 in my living room already this morning, so i guess they want to move in with me. whats the best way to kill or at least depopulate the colony?

I read the semolina works a treat, anyone have any experience?

 

Nippon Ant Killer liquid by their "run". They will take it away to feed the colony. Note the word KILLER - good job they can't read,
