It's not a myth.

I have seen the termite and ant holes in both liners and in flex. I even have a piece of flex somewhere with termite grooves and holes. But I can't tell you how to know if you are at risk or not, except to say that I would recommend that you avoid, at any cost, using flex underground: it will spring leaks even without termites, after a few years.

On the other hand, I don't recall any cases of liners being damaged by pesticides.
