Nature’s Dome Drain Fly Killer Gel – 1 Gallon – Kills & Prevents Drain Flies, Fruit Flies & Sewer Flies – Natural Plant-Based Treatment for Sinks, Pipes & Drains – Safe for Septic Systems

Eliminate drain flies at the source with Nature’s Dome Drain Fly Killer Gel (1 Gallon) — a powerful, plant-based gel formula designed to kill and prevent drain flies, fruit flies, and sewer flies by breaking down the organic buildup where they breed.

Unlike surface sprays that only kill visible flies, this thick, slow-draining gel coats the inside of pipes and drains, penetrating deep into bio-sludge, grease, and organic residue to destroy eggs, larvae, and adult flies. It continues working long after application, helping prevent reinfestation and keeping drains clean and odor-free.

Safe for septic systems, plumbing, pets, and people when used as directed, Nature’s Dome offers a natural yet highly effective alternative to harsh chemical drain cleaners.
