Ant killers

[Nadfan]

Morning all.
Anybody on the Joburg East rand that recently had the successful service of ant killers/ terminators? At a reasonable cost I might add. The bastards are in my foundation & walls it seems. There seems to be varied opinion on the methods/ products used as well, ie contact spray vs microbeads/ pellets for them to carry back into the colony. Any recommendations/ comments welcome.
Thanks
