DIRECTIONS FOR ELIMINATION OF EGG LAYING AND LAVAL DEVELOPMENT OF FLIES:
A total sanitation program needs to be undertaken. Standing water, food waste, and other potential breeding areas must be cleaned up. Once that is accomplished, the primary breeding area(drains) can be attacked.
For floor and trough drains: take of screens and scrape the organic matter from under the screens and tracks.
DRAINS:
Clean Out: Apply 4 oz. per drain for 5 days. Pour product around the opening so it flows down the sides of the vertical pipe walls.
Monthly Maintenance : Apply 4 ounces per drain.
Treat the drains monthly to assure that the build up does not return.
Flies can re-infest an area within 2-3 months if use is discontinued.
Recommended 2-3 monthly applications per month.
Make sure to treat every drain except toilets and urinals. Floor drains, hand sinks, beer trap drains, cooler drains, and all others must be treated. If some drains are clean and others are dirty, flies will just move to another area to lay their eggs.
Use more product for larger drains. Each treatment of a floor drain should be at least 4 ounces . Basically, use about an ounce of product for each 1" pipe diameter.
Make sure to pour the product all the way around the opening to coat the pipe walls.
Pouring product down the center of a drain opening will not eliminate flies. Remove screens if they interfere with proper application.
Discontinue pouring bleach down drains. This can kill large numbers of the beneficial bacteria and reduce effectiveness of DF 5000.
