Dear Ed: I hope you can help me. Some years back I was at the Florida Builders Show and met a Pest Control Company that had some very fine stainless steel mesh, they told me it was used all over Hawaii. Do you know of this product? It is used as a barrier. I am a contractor and my own home is frame construction which I built 16 years ago. I'd like to install it before I add Hardie Board siding. I sure would appreciate your help. Thanks, John.
