According to the manufacturer, Eco PCO WP-X will not stain or cause damage to any painted or varnished surface, plastic, fabric, or other surface where water applied alone would cause no damage.
You will mix 1 water soluble pouch of Eco PCO WP-X per gallon of water and apply at a rate of 1 gallon diluted solution per 1,000 sq ft of surface area.
Yes, Eco PCO WP-X is labeled for phorid flies, but it cannot be poured in a drain as the product label strictly prohibits that. If the Phorid flies are breeding in drains that generally indicates a buildup of organic matter. DF 5000 Drain Gel is a great product to use to get rid of that matter and this pest. Adding Gentrol IGR Aerosol to the treatment program can definitely help break the reproductive cycle. You can also use insect glue traps to capture the breeding adults which will help you monitor the infestation and help eliminate them from the breeding pool.
