Does Demon WP wash off the outside of a house in the rain?

We are trying to fight stink bugs.


Demon WP typically leaves a 30 day residual even if it rains. The places on your house where the product is protected from direct rain contact like against the house that may be somewhat sheltered by the roof line, will last longer than other places.
