Do not let anyone spray as this will cause budding and they will start a colony
inside. I would bait with Terro ant baits on the interior and use Amdro
granules on the exterior. They should decline shortly. I would also make a note
to apply amdro again in the spring around the exterior perimeter. JTV

Hello Everyone,
I was just alerted by a staff person that works in a basement area that ants
appear to be coming up through the floor somewhere. I checked it out, and
although it's not plague proportions, there are enough crawling around where it
does seem like something beyond "just a few random ants".
-The concrete floor down there is in pretty good shape- no major cracks, but
there are probably a few that pavement ants could fit through.
-Nothing new was recently brought into the space that may have been
contaminated (that the person knows of).
-Although it has been cold here for a while (20's-30's F), this week has really
gotten cold (10-15 F). I have heard insects make their way into buildings in
the fall to escape dropping temps, but can that type of behavior go even
further into the winter where a relatively sudden drop from 30 to 10 might
cause insects under a basement slab to start moving around trying to find
another place to be?
Sorry I don't have pictures yet, the specimens are currently in the freezer. I
should have official pictures to confirm species in a few hours. I am 95% sure
they are pavement ants.
Do pavement ants (assuming they are) present a problem in museum environments
aside from indicating a porous building envelope and providing food for other
more problematic pests?
Does anyone have any tricks for dealing with these types of ants in a museum
environment?
If anyone has any thoughts, they would be appreciated!
Thanks!
Todd
