Best way to get rid of ants?

[Pandora]

talc can sometimes work, if you dont have pets inside?

Any other suggestions for inside ants?

Pet anteater or echidna?

If that wasn't helpful, at least give asking the agent a try. You can write a letter, then call and ask if they got the letter, then a week later if nothing's been done, ask to speak to someone else.
Ants in the house is not okay - stress the whole 'not okay because we have kids' and whatever other argument you can think of.

Do you know where they are getting inside the house from? A layer of talcum powder along a door entry can stop them- they don't like the feeling of it on their feet. Or if you don't know how they are getting inside, maybe try running a strip of ant sand all the way around the house- if that is possible.
Is there anywhere in particular they are making their way to, or are they just wandering all over the house?
