Well, I DID say I didn't know if it was a myth or not.

I do not know if bug killers damage liners, but most warn about what you spray them on. However, I believe that the termite-icides form a crystaline barrier when injected into the ground (Any Orkin guys or gals here?) and that probably won't damage a liner.

We've had some nasty droughts and floods in NJ--after years of drought that killed our lawns, we had a flood that devastated Millburn and flooded downtown Bound Brook--made TV news here and abroad!

I guess I would never think of burying TigerFlex--if you can bury it, why wouldn't you use regular PVC?
