To Reply to hazard concern of corn syrup and boric acid this is from the MSDS
of terro and bait which is the same thing basically as the posted recipe. Not
that I would condone eating borax there were some home remedies that involve
consumption of it. As far as using a home made mix in an institutional
setting... I would not as you need to have a real MSDS for a real product in
order to be compliant with health and safety standards.

Ingestion can be a concern, but I think only in quantities far greater than the
few drops in the tray. Of course, pregnant women should always practice more
caution around any sort of chemical. The pest control tech who told me about
the homemade traps uses the same traps in restaurant kitchens.

Hi Alan, that sounded really good to me and I was considering using it at home
because I have a tiny ant infestation, but I have found several MSDS sheets
that consider it relatively dangerous for humans if accidentally ingested and
include adverse reproductive effects, harm to developing children and
potentially teratogenic effects (seen so far in animals only). I believe these
are mostly in the case of ingestion as the MSDS is not 100% clear on that, but
I worry since ants do walk around all over the place and especially around
areas where we store food. Is this something to be worried about?
Best,
Angelica

We used a homemade solution of boric acid and corn syrup. It worked like a
charm, and you know exactly what's in it. 5 milliliters or one teaspoon of
boric acid to 60 milliliters or a quarter cup of corn syrup, mix well, place a
few drops on wax paper or a little tray near the ant trail but away from human
feet. You can store what you don't use in a sealed jar and replenish the bait
daily. Discard after a couple of weeks. It's safe around people and larger
animals, and unless you smear it on something it won't affect your collection
materials.
I also would not bother with exterior spraying just for ants (though it really
shouldn't affect your collections unless an air intake was sprayed). The only
way to get rid of ants is to get the pesticide into the colony, and the only
way to do that successfully is to get the ants to carry it in. The corn
syrup/boric acid trick works well because the ants carry it back into the
colony where it is fed to all the other ants. A pest control tech taught me
this and it has been successful for me.

We have noticed a larger than usual number of ants entering a collections area
from a crack under an exterior door. The best IPM solution is clearly to
request this crack be sealed, but until this repair can be made, is it a danger
to the collection to place ant bait traps inside the collections area beside
this door? (The artifacts stored in this area are primarily furniture,
vehicles, and equipment.) If traps are not harmful, what type of a trap would
be best, and what type should be avoided? Also, would it endanger the
collection if facilities sprayed for ants on the exterior of the building?
We could buy a recommended product, but these are the traps our janitorial
staff currently have available for non-collections areas: 1) Terro
Multi-Surface Liquid Ant Baits (enclosed bait station with 5.4% Sodium
Tetraborate Decahydrate aka Borax) and 2) Raid Ant Baits (enclosed bait station
with .01% Avermectin B1).
Thank you for any feedback,
