I read that it stains vinyl and that it soaks up into brick.
Demon Max has the ability to do both the things you mentioned, both stain siding due to its oil base, and soak into brick leaving an oily finish and not providing as much chemical on the surface for an insect to absorb. It would be better to use a product like the Demon WP which would sit on the surface better, not stain, and last longer.
