Thanks. I am hoping to eliminate it, by hitting the main plant
hard and cleaning up well in the winter and spring. But that
relies on its eggs not being viable for more than about 6 months.

You don't know any of the details of how and where it overwinters
(except in crevices), how long eggs remain viable and so on?
I have tried to find decent references to this and failed dismally.
