During the summer I briefly had a Monomorium ergatogyna colony and fluon didn't work 100%. M. ergatogyna have really small workers and better at escaping than Solenopsis molesta. I used the same container, a plastic 2.5 gallon fish (tank?), and i washed it out as I always do (soap, hot water and some bleach), but...
During the summer when it was hot and dry, cooking oil was the only one that kept my Monomorium ergatogyna colony from escaping. They could cross the fluon, a bit of issue crossing it, but the occasional worker would very slowly cross it, and I applied it exactly the same as I always do. But, now that its much colder and more humid overall, the M. ergatogyna can cross the cooking oil without any issue and now fluon does a vastly better job at keeping them in.
I do keep them in the garage where its warmer and drier than usual, but usually the garage door is partly open so it is still affected by the weather a bit.
Anyone notice anything like that, where at different times of year when its usually colder/hotter/drier/humid, that different ant barriers work differently?
Or is it just a coincidence or other factors are in play, when the cooking oil (olive oil) worked before, but now it doesn't. And fluon now works better at keeping them in, when it didn't before. Nothing else different that I'm doing, only thing different from what I can tell is the season change.
