The Horned lizard only eats Pogonomyrmex (and termites). They won't eat Argentine ants at all, which is why they've died off mostly in California.
As for these queens. They should be free I still wouldn't want them though. Anyone that has them in their area (and hopefully no one actually introduces them into their area if they aren't there)...could just as easily pour water on the nest and get free queens. They, along with Pheidole megacephala, have been the easiest two ant species to get. When my ex-roommate/friend got the Pheidole megacephala they must have been really really easy to get...as he sucks at catching things lol. Couldn't even use a HUGE bug net to catch butterflies (well actually, I think they are actually day-time moths. The small orange moths that get the flowers)...but anyway...yeah...xD
In any case, Argentine ants are so easy to get lol.
