Drain Gel Fly Killer, manufactured by American BioSystems, is a concentrated bacterial gel used to clean grease, grime, and other organic debris from drains or heavy equipment to control drain flies.
Unlike other cleaning agents, Drain Gel does not push grease further down the pipes to cause problems later. Instead, it eats away the grease with its propriety formula, which contains over 550 billion cells and includes a microbial grease degrader. Drain flies and gnats live and breed in drains compacted with waste, so when Drain Gel removes their habitat, it also gets rid of them.
Drain Gel is easy to use. Pour it into drains or spray underneath heavy-duty equipment and other non-drain areas for quick and effective removal of foul odors and grease.
Tools needed:
No tools are needed to apply Drain Gel Fly Killer.
How to use:
- Step 1: Prepare the drain for the application by running 1 to 2 gallons of warm water down the drain.
- Step 2: Apply 4 oz of Drain Gel around the lip of the drain so that the solution will run down the sides of the pipes. If a sink has multiple drains, it is recommended to apply Drain Gel to both. Do not use the sink for the next 8 hours.
- Step 3: After 8 hours pass, rinse the sink and repeat the application for the next 3 to 4 days.
Where to use:
Drain Gel is beneficial for residential or commercial kitchens and can be used in sinks or drains in restrooms and other areas where drains are present. It can also be used as a spray to reach under heavy equipment, access cracks and crevices, and other difficult-to-reach places.
When to use:
Drain Gel Fly Killer can be used anytime to remove waste and sludge from slow drains, cracks, and crevices and out from under heavy equipment. Apply at night or when you know the sink will not be used for about 8 hours, then rinse away in the morning or once the time has passed.
Safety Information:
Drain Gel Fly Killer is safe to use around children and pets, according to the product label instructions. Always wear the proper personal protective equipment (PPE) when handling or applying this product.
Special Considerations:
Drain Gel is not an insecticide; however, it removes the organic material that flies are attracted to. If there is a heavy infestation, we recommend using a Pyrid insecticide alongside Drain Gel.
