Will Eco PCO WP-X kill spider?
I am looking for product that don't leave any white residue on dark surface. We use black lava rocks for our flower beds. Is the ECO PCO WP-X perform comparable to Cyber WP? Thanks!
All wettable powder insecticides including Eco PCO WP-X will leave behind white powdery residues. If you would like to use a product that will kill spiders and is all natural like the Eco PCO WP-X but won't leave behind the unsightly residue we recommend using Essentria IC3.
