In my front yard there was a massive nuptial flight taking place. My best advantage was that the ones that were currently mating landed on my parents car and i scooped them up once they were done.
Now about a month later i have 4 still alive 3 in a dirt container that i can't see through but they are most likely alive. The other one is in a small starter formicarium with about 7 workers and a huge brood pile.
