Wow! That's good to know.

So let's try this another way.

If I put up a trellis, and grow Boston ivy on it, how far from the
house should it be, to prevent it from reaching over and growing onto
the walls?

Or, is there a colorful climber that won't harm wood siding?

Keep the Boston Ivy for a ground cover away from wood houses. You can let it
grow up solid concrete. Even Boston Ivy growing on bricks or cinder blocks
can penetrate the mortar joints. Something colorful and safer for a trellis
attached to the house would be clematis. One difference is that it won't
climb as high as ivy and is probably a little higher maintenance (just
because ivy is almost zero maintenance in terms of fertilizer,
winterization, insects, etc).
