Or, you can just Take the reproductives, and a couple workers, (and assuming you have a major) And Preserve them in Rubbing Alcohol. I know it might sound mean, but if your colony starts to die out (queen starts laying poorly) then you will have some kind of remembrance.
Bob, Sending Those alates, really would be a waste of time for a few reasons. They wont be in sync with the species in the wild, the males would die, and the females would probably get stressed out and in the long run probably not mate. So it would just be money wasted in sending the alates. And probably the native country's Canada and the USA you cant send ants to these countrys.
The wild population is probably more than fit to reproduce what is needed and doesn't need 20-30 alates, out of 100's of alates in the hundred thousands of wild colonies that are probably around.
This also leads to another subject, just stick to native species and you wont have this problem, lol. But their are answers to your hypothetical question.
