Ants & Insecticidal

Living in Florida for the last six years or so, has been an introduction to many of insects - some have been non-problematic, some have been super challenging like the dreaded lubber bug which if not treated with a potent insecticidal during their nymph stage can only be controlled in the garden by use of a brick.

For ants and more, I've found this recipe to work best:

http://en.wikipedia.org/wiki/Boric_acid
"Boric acid was first registered in the US as an insecticide in 1948 for
control of cockroaches, termites, fire ants, fleas, silverfish, and
many other insects. It acts as a stomach poison affecting the
insects' metabolism, and the dry powder is abrasive to the insects'
exoskeleton.

Boric acid is generally considered to be safe to use in household
kitchens to control cockroaches and ants.

Homemade ant bait can be made
by dissolving:
1 teaspoon (5 mL) powdered boric acid and
10 teaspoons (50 mL) sugar into
2 cups (500 mL) of water;
this mixture can then be absorbed into cotton balls which are left near
ant trails. This reportedly will be carried back into the ants' nest,
decimating or even completely wiping out the colony."
