Anyone with personal experience with these tiny pests -

Tips / tricks do / don't do appreciated.
I have done some internet reading on them and realize
not to use spray insecticide.

Laboratory Evaluation of a Boric Acid Liquid Bait on Colonies of
Tapinoma melanocephalum Argentine Ants and Pharaoh Ants (Hymenoptera:
Formicidae)

I believe the bait was ground liver.


Thanks.
Your link has the abstract - I'd need to pay to see the study, and
then I probably wouldn't understand the scientific lingo ..
But it did remind me google the 2 products that the exterminator used
- I found some additional info on those web sites :

Here's one that google found that uses boric acid :

I assumed the professional product would be restricted - but I think I
can get some and do the treatments myself after the 2 additional
visits by the exterminator. if necessary.

The main draw of boric acid is that it is not toxic.
It dehydrates the buggers (roaches included) and doesn't
poison them, so they can not get tolerant of it.

The problem is they just stop eating it. I can't find a bait they will
eat, commercial or home made. I don't even find much I eat that they
will get in. If they would I would make bait out of it.
I am spraying bifen and moving them around. I can eventually locate a
nest behind a wall or something and kill it but they come back.
That is also the problem with baits. You may kill that queen but the
next colony knows not to eat that ****.
