Why Are Black Flies Coming Through My Bathroom Drain?

Flies Coming Out of Sink: The Hows and Whys

Ever had the creepy experience of flies coming out of your sink? It's an image straight out of a horror movie - you walk into your bathroom or kitchen, only to find a swarm of tiny flies emerging from your sink's drain. But there's a logical (and rather icky) reason behind this unsettling phenomenon. Before you go blaming the supernatural or considering moving out, let's unravel the mystery behind these unwelcome guests.

Why Flies Love Your Sink

What makes your sink so appealing to these tiny pests? Drains offer an ideal environment for certain types of flies to breed and thrive. The moist, dark conditions paired with a buffet of organic matter (like food scraps, hair, and soap) can become a haven for these insects.

Understanding the Drain Fly Invasion

The Culprit: Meet the Drain Fly

When we talk about "flies coming out of sink", the primary culprit is usually the drain fly. Also known by other names like sewer flies, moth flies, or filter flies, these tiny pests are different from the common housefly. Here are some quick facts to help you identify them:

  • Size: Tiny, usually 1.5 to 5 mm in length.
  • Appearance: Light gray or tan in color and have a fuzzy, moth-like appearance.
  • Habitat: They lay their eggs in the organic matter found in drains, hence the name.

Why Your Sink is a Drain Fly Haven

Remember the last time you didn't clean your sink for a week or so? Bits of food, grease, and other organic debris can build up in your pipes. For drain flies, this buildup is like a five-star hotel. Here, they lay their eggs, which then turn into larvae that feed on the gunk in your drains. And voila! Before you know it, you have a drain fly infestation.

Prevention and Solutions

Tired of sharing your home with these pesky flies?
Here's how you can evict them and ensure they don't come back:

  1. Regular Cleaning: Ensure your sink and drain are clean. Regularly flush with boiling water or a mix of baking soda and vinegar to break down the organic buildup.
  2. Use Mesh Screens: Fit your drains with mesh screens. These screens will trap larger debris, preventing buildup and making your sink less appealing to drain flies.
  3. Professional Help: If the infestation is heavy, it might be time to call in the pros. We will conduct a thorough cleaning, use specific treatments to eliminate the flies, and give advice on future prevention.
  4. Seal Cracks and Gaps: Ensure there are no cracks or gaps in your pipes or around your home. Such openings can be entry points for drain flies and other pests.

In Conclusion

The appearance of flies coming out of your sink can be disturbing. However, with the right knowledge and a proactive approach, you can tackle the issue head-on. Regular cleaning, preventing organic buildup, and seeking professional help when needed will keep your drains fly-free. So, the next time you see a tiny winged creature emerging from your drain, you'll know exactly what to do!

We luckily had gravel drainage so he recommended cleaning out our septic tank completely and putting biodegratible in the drainage field. He was here from 4:00-6:30 and explained everything to my husband. In the past when we had our septic tank pumped they did it incorrectly. I feel confident in Steven’s work and we have a 12 month guarantee. It was costly but for what he did worth every penny. Thank you Steven for your expertise job.
Steven was so awesome and very knowledgeable of the system that he taught me a lot. He did a good job alone and I would recommend and already did to someone else. I like the fact he drove a long way and there was no charge for him to come out! I will use him again in another 4-5 years if he...

Ken H was excellent! He was professional and efficient in diagnosing my problem with my water heater. He offered various options for replacement and went out of his way to get the job done the same day. I would highly recommend him and Rooter Plus!

I called the office for water leakage on Sunday morning and they schedule me with Technician arrival in 30 mins. Jason reached on time, investigate the problem and able to find the source of leak in few minutes, which was definitely tricky and I believe only an expert eye like Jason can capture it. He walked me over the issue, fixed it and saved my Sunday morning. RooterPLUS is on my speed dial now for any plumbing issues.
It is usually unlikely that you see someone young working hard and have a good attitude along with it. Robert definitely displayed that while he was at work today and I had the pleasure to meet him and tell you about it. Keep up the good work Robert it will pay off!
