We've been living in a very heavily wooded area for about a year now and to be honest there's bugs out here that I think even God forgot about. Thank God 99% of them are outside. I'm not familiar with the type of ants that you're talking about but I did have a small probelm with ants on my kitchen floor { these ants were pretty big...don't think they were Carpentar Ants } so I bought some stuff on the internet called Drione. I've included the link to the company below. I dusted once....problem gone. Sorry I couldn't have been of more help .... but I strongly suggest you hook up with an Exterminator and go on a Scheduled Maintenance Program. It's well worth the investment. Try and do some research on the internet with the problem you're having.
