I took some measurments around one of the nests I found, which might interest you Necturus, they where nesting on the beach, in very damp sand, the outside temp was 35-40C, at 10cm depth the temp was 28C, and at about 50cm the temp was 26C, and it didnt fall much below that even at 1m, there where ants all the way from 10cm - 1m down, although i didnt find the main nest area. At night, the tempreture outside dropped to as low as 5C, although the sand remained at about 15-20C, the latest measurments I did where at 2am, after that the tempreture would have dropped allot, as there is allot of wind, and no cloud cover, mornings where freezing cold, although it warmed up to 25C very quickly, in about an hour, then peaked at 40C at lunchtime.....so I would have expected these ants to be fairly hardy, but not many people had luck with them
the majors where out and about constantly with the minor workers, they where living along side some crematogaster and ponera ants, and definitly seemed to be the dominant species, but then they are 5 times bigger than any of the ants they where living with, quite aggresive ants aswell sumtimes, I was bitten several times lol although out in the open they tend to run away from you, very fast
You could use a sprinkler system to get them to build cimmneys, obviously you will need good drainage, so might not be an option, but i wuld imagine that spraying the nest area every day just with a garden spray may induce them protect their nest with a chimmney
The Golden ants where considered to be a good luck omen to many of the people I met and spoke to in Gambia, because they help subdue the growth of other species like the Ponera, which have a nasty sting, possibly because they steal food from them, as no one could tell me how they subdued other species, I was told they also prevent Termites nesting close to their nests
