Sprayed my house yesterday and I’m already seeing dead roaches. I’m just curious as to how long we leave the white residue down before I clean and put everything in order?
Demon WP Insecticide are usually not removed after application so that it can continue to kill insects for up to 90 days. It is best to leave it there as long as there is activity.
