You really use *all* the things listed in the article that you linked to?
Personally, what they list for baits I really don't want in the garden or my containers where I'm growing edible plants. The exclusion aspect is problematical if you're surrounding buy several hundred acres...hay fields, pine forest, brush, etc.
What I have found that works for container/potted plants are those foam pads that link together....folks put them in playrooms and use them for exercise mats. I can sit a pot on one of those and spray the mat down good with an ant poison and the ants don't invade the pots. I guess it creates a "no man's land" that keeps them from crossing.
The ants are bad around here. Once I even went as for as putting boric-acid peanut butter stations out around the garden...all that that succeeded in doing was to create little beeping-like sounds....I think it was ants burping.
