I ended up using diatamatious (sp?) earth. Great stuff!
I sprinkled it around the base of the pots, in the area of concern.
Haven't seen anything since.
I did get some insectacidal soap in case. Hopefully I won't need it.

A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort!
