I have had sucess with plain ole Borax on some kinds of ants. Its cheap
and you may already have some in your house for cleaning purposes. Just
dust the mounds and immidiate area with it plus any visible ant trails
if you have them.


the problem with borates is that it is a repellant and by dusting mounds
can actually cause the colony to "bud", where now that you see the one
inactive mound you may have three active mounds that will show
themselves in a couple of weeks.
