I live in a Tower block and we are infested with Pharoah ants. The council gave us poison containers but that didn't work. Any advice would be most appreciated.
There is a detailled article on how to remove Pharoah ants at this site: http://www.antcontrols.com/phar.htm click on the red link that says ant trails: baiting. it is a US university document but I guess ants is ants
