Okay, I was confused myself, so I looked those two kinds of ants up. The Raspberry Crazy Ant is the one that was introduced about 2002 in Houston area. And it's the ant that for whatever reason is especially attracted to electrical equipment, resulting in a lot of expensive damage to various things, including, I guess, A/C. They only use the same insecticide that's used on termites for this one. Now that is definitely NOT good news!
The Argentine Ant is another accidentally imported ant. It does displace other ants, it said. It's a danger to native plants and species like lizards, is an agricultural pest and can invades buildings and homes. Do not spray with insecticide (which can make them worse), but you can use poison baits. Oh lord! Another bad news is that apparently, people have to figure out which species of ant they have. The ants that seems to be increasing on my place now reminds me of sugar ants...tiny dark ones. I'm hoping they ARE sugar ants, but with my luck they aren't! Darn invasive species!
