Finally got rid of the bathroom gnats!

I tried everything from boiling water to store-bought sprays, but nothing worked until I found this. The foam reaches deep into the pipes where the larvae hide. Within two days, the flying insects were completely gone. Highly recommend for anyone struggling with drain flies.

Worked partially

It reduced the number of flies significantly, but didn't eliminate them entirely on the first try. I had to apply it twice more to get full results. It might depend on how bad the infestation is. The product itself seems safe for my old pipes which was a major concern for me.

Safe for pets and effective

As a dog owner, I was worried about using insecticides near the floor drains where my pet drinks water nearby. This product gave me peace of mind as it is non-toxic once settled. It cleared up the moth fly problem in my guest bathroom quickly. Will definitely buy again.

Effective but requires patience

This product works well, but you need to follow the instructions carefully. You have to let it sit overnight without running water. After three applications over a week, the infestation in my kitchen sink drain was eliminated. Deducting one star only because the nozzle is a bit short for deep floor drains.

Good value for money

One tube lasted me about two months of weekly treatments for two bathrooms. It's much cheaper than calling an exterminator. The foam consistency is perfect for sticking to the vertical sides of the pipes. A solid solution for common household pest issues.

Great preventative maintenance

I use this once a month in all my bathroom drains to prevent clogs and bugs. It has a pleasant smell compared to other harsh chemicals I've used. Since starting this routine, I haven't seen a single gnat in my home. Easy to apply and very effective.

5 FAQ

Q: How long should I wait before running water after application?

A: For best results, we recommend applying the gel at night and waiting at least 6 to 8 hours before running any water down the treated drain.

Q: Can this be used in kitchen sinks as well as bathrooms?

A: Absolutely! This product is designed for use in any drain where organic buildup occurs, including kitchen sinks, bathroom sinks, showers, and floor drains.

Q: Is this product safe to use in homes with septic tanks?

A: Yes, our formula is septic-safe and will not harm the beneficial bacteria required for your septic system to function properly.

Q: What is the shelf life of this product if unopened?

A: When stored in a cool, dry place, an unopened tube has a shelf life of approximately 2 years from the date of manufacture.

Q: Does this kill the adult flies or just the larvae?

A: The primary action targets the larvae and eggs living in the biofilm inside the pipes, which breaks the breeding cycle. Adult flies will die off naturally once no new ones are emerging, usually within a few days.
