My home exterior is cedar wood. I applied Demon WP. How long will the white Residue last ? Will the next rain get rid of it? Thank you.
Demon WP does leave a visible white residue on darker surfaces, but that should not leave any permanent stain. The rain/sunlight will break it down over time or you may also wipe/scrub it off with soapy water, You may also check out a water-based insecticide such as Temprid FX which leaves no visible residue once it dries.
