Crazy ants combat little red fire ants

[Midnight Rambler]

There are no phorids that attach LFA; I think they're probably too small, not to mention cryptic. There are some parasitic wasps that attack them, but they're not very well known and I don't know if anyone is actively studying them as a control. They also get into the ants by laying eggs in plants where the ants then pick up the small larvae, so they can sometimes cause damage to plants. The different species tend to favor different plants to lay eggs on though, so if the one that attacks LFA doesn't use something economically important it might be a usable biocontrol.
