  1. You mean they get inside? Posted 11 months ago
    1. Yes, they are all around our camper and have started scouting indoors as well. We have been stung multiple times already, so we are researching natural control methods right now.
      They also REALLY love electronics, and I was stung when I picked up my power pack when mothing out back a couple of weeks ago. So painful!

      1. That does sound scary, especially given their numbers! I believe we had red forest ants that are possibly similar, almost everybody has once sit in the wrong spot and found out. Posted 11 months ago
        1. I was just watching a short documentary on Solenopsis invicta last night. Georgia Tech has been researching their behavior and the physics of their behaviors--and they are capable of forming:
          - a knit that serves as a raft (during flood conditions)
          - a viscoelastic structure called an "ant ball"
          -they also act like a viscous fluid when put under stress/strain

Solenopsis invicta X richteri, is a hybrid between S. invicta (the red imported fire ant) and S. richteri (the black imported fire ant). The hybrid fire ant, along with both S. invicta and S. richteri, is a major agricultural and urban pest throughout the southeastern states that also causes both medical and environmental harm resulting in a cost of many millions of dollars per year for southeastern states.
