Ants in Pots
Rick Buell via pbs (Wed, 04 Apr 2018 09:36:52 PDT)
Small pots are easy--wash them out, destroy the ants, and replant with clean medium. Infestation of larger plants could be effected by application of diatomaceous earth to the main ant hill. It's basically chalk, but razor sharp on a microscopic level. It cuts up the exoskeleton at the joints and causes insects to dehydrate rapidly. Just don't inhale it!

I think I read that limonene
dissolves or penetrates chitin which arthropods
and mushrooms are made of. This makes it
vastly safer for cats than the
pyrethroids
which are nerve agents. Cats have poorly myelinated
nerve
axons, making them especially
susceptible to nerve toxins (and bugs have no
myelin if I recall correctly). I spray
limonene all around the cat dishes
to kill
ants but it does not persist long due to high vapor
pressure.

Look up limonene,
aka orange oil. Don't know what it would to do
plants,
but
it
certainly caused the carpenter ants nest to disappear.

Dennis brings up an
interesting point (I've had problems with ants
farming mealies and scale.) that I
learned from a pest control
person. Ants farm aphids and other insect-type
creatures. I was
having a
terrible problem with ants around and under the house and
was
told the ugly 20-foot laurel
hedge in my front yard (I had just moved
in.) was a major hiding out place for
them. There were some 150 feet
of hedge in fact so it was a major undertaking given the
bushes were
20-25 feet tall. It
was worth all the hard work!
I removed almost all the laurel
hedges within the first year and have
not had problems since.
