Lasius Niger in MO?

[SteveMan]

I am brand new with ants and trying to get myself a queen. I'm in Missouri, South of St. Louis. Through google I have discovered that there are TONS of Lasius Niger nests all over our property. What are the signs that there are nuptial flights going on?

i think it has to be warm and dry, but after it has rained recently.
