Prevention Strategies for Drain Flies in RVs

Now that you have understood what attracts drain flies, let’s discuss effective prevention strategies to keep these disturbing insects at bay and ensure a camper free from their unpleasant presence. Here are some key prevention strategies:

Maintain Proper Black Tank Care

The black water tank holds sewage and is the most common breeding ground for drain flies in campers. To deter flies:

– Empty and flush regularly, at least every 4 days. Do not allow solid waste to accumulate.

– Use an enzymatic black tank treatment like Happy Campers to break down solids and control odors that attract flies.

– When emptying, spray wand wash down sides to dislodge any fly eggs and larvae.

– Leave tank valves open when not in use to ventilate.

Keep Gray Tanks Clean and Flushed 

The gray tank holds wastewater from sinks, and showers and is also a breeding spot. Prevent flies by:

– Empty frequently, every 2-3 days. Do not allow water to get stuck.

– Using a tank rinse like Happy Campers or filling halfway and driving to agitate and rinse insides.

– Flushing with disinfectants like bleach or vinegar to kill larvae.

– Keeping sink and shower strainers clean of hair and debris.

Eliminate Food Sources and Moisture Traps

Flies are attracted to any organic matter they can feed on. Eliminate attractive conditions by:

– Frequently cleaning sink and shower drains to remove grease, hair, and food particles. Use a drain brush and baking soda/vinegar.

– Using sink strainers to catch food scraps so they don’t go down the drain.

– Storing food properly in sealed containers, not leaving dishes in the sink.

– Fixing any leaks immediately and drying out wet areas to eliminate moisture sources.

Install Fly Traps and Repellents

To control adult drain flies, install traps and repellents:

– Use non-toxic fly sticky tape near drains and vents where flies gather.

– Set out bowls with apple cider vinegar and dish soap to attract and drown flies.

– Utilize electric UV fly traps for large infestations. Position near the breeding site.

– Apply natural repellents like lemon, basil, mint, or eucalyptus oils.

Address Plumbing Issues Promptly 

Any water leakage or malfunctioning plumbing provides ideal breeding conditions. Stop issues before flies take over by:

– Inspecting routinely for small leaks under sinks, at pipe joints, and water heaters. Repair immediately.

– Checking sink and shower seals for cracks, replace them if worn out. 

– Monitoring gray tank sensors for accuracy, cleaning/replacing if malfunctioning.

– Have a professional inspect the black tank for any cracks or defective parts.

How to Find If You Have Sewer Flies in Your RV

Before checking the strategies to address sewer fly issues, it’s important to identify whether these pests have taken residence in your RV. Understanding the signs and implementing a systematic process for detection is key to effective pest management.

Visual Inspection: Begin by visually inspecting common breeding grounds, such as drains, sewage systems, and moist areas. Look for small, moth-like flies.

Check for Larvae: Sewer flies often lay eggs in organic matter. Inspect drains and other potential breeding sites for the presence of larvae, which resemble tiny worms.

Odor Detection: Sewer flies are associated with foul odors. If you notice unpleasant smells, particularly around drains or sewage systems, it may indicate a sewer fly infestation.

Pet Areas Inspection: If you have pets, inspect the areas they frequent for signs of sewer flies. Ensure proper waste disposal to minimize attractants.

Nighttime Observation: Sewer flies are more active during the night. Conduct observations in the evening to spot their presence around potential breeding areas.

Professional Inspection: If uncertainty persists or if signs of an infestation are evident, consider seeking professional pest control services. Experts can conduct thorough inspections to confirm the presence of sewer flies and provide tailored solutions.

By systematically following these steps, you can accurately determine whether sewer flies have invaded your RV, allowing for timely and effective intervention.

What Causes Drain Flies in Campers?

Drain flies, also known as moth flies or sewer flies, are small flying insects that thrive in moist environments. They can be confused with fruit flies but do not have red eyes. In campers, they are often attracted to the black water tank where sewage accumulates. Their larvae feed on bacteria, fungi, and organic matter found in standing water and sludge.

Are They Fruit Flies?

Drain flies, often confused with fruit flies, are small insects belonging to the Psychodidae family. Unlike fruit flies, they are drawn to damp environments rather than fruits. Differentiating between the two is important for implementing targeted prevention measures.

Standing Water

Standing water serves as a breeding ground for drain flies. Any swelled water in sinks, shower stalls, or other wet surfaces becomes an ideal habitat for these pests. Eliminating stagnant water is a key step in preventing infestations.

Food Particles

Food particles left in drains attract drain flies, providing them with a food source. Regularly cleaning drains and ensuring proper disposal of food scraps helps remove this attractant, reducing the risk of infestations.

Leaky Plumbing or Water Systems

Leaky plumbing or water systems contribute to the damp environment in which drain flies thrive. Identifying and promptly fixing leaks is essential to prevent the establishment of breeding grounds within camper plumbing systems.

How to Get Rid of Existing Drain Fly Infestations

If drain flies have already established themselves in your RV, more intensive efforts will be needed to fully eliminate them. Here are steps to exterminate an existing infestation:

Use Drain Cleaners and Enzyme Treatments

Employing drain cleaners and enzyme treatments is a key step in breaking down organic matter within drains. This disrupts the breeding grounds and life cycle of drain flies, helping to eliminate the infestation. Treat all drains, tanks, and affected areas according to product instructions.

Flush Pipes with Boiling Water and Cleaning Products

Heat kills flies at all stages. Flush pipes with boiling water to dislodge and remove any remaining larvae or eggs. Enhance the effectiveness by using cleaning products such as vinegar and baking soda, which not only help break down residue but also disinfect the plumbing system.

Use Smelly Products Like Vinegar or Ammonia to Deter Flies

Flies dislike the strong odor of vinegar, ammonia, garlic, and citrus peels. Place bowls around drains or soak paper towels. Apply these around potential infestation sites to deter flies from returning, acting as both a preventive and remedial measure.

Vacuum Up Adults

Physically removing adult drain flies is a practical and immediate method. Use a vacuum cleaner to capture flying insects, particularly around areas where they congregate. Empty the vacuum bag quickly to prevent any potential re-infestation.

Set Out Drain Fly Traps and Monitor for Activity

Strategically place drain fly traps in key areas to capture adults and monitor activity. Regularly check the traps to assess the effectiveness of your eradication efforts and adjust your strategy accordingly.

Hire a Professional Exterminator if Needed

For severe, persistent infestations, professional pest control may be required. They have commercial products and methods to eradicate flies at the source and prevent re-infestations.

By following these methods, you can successfully eliminate existing drain fly infestations, ensuring a clean and comfortable living space within your RV.

Additional Tips for Preventing Drain Flies in Campers

Beyond the main prevention measures already covered, some additional tips can further help deter drain flies in campers:

Regular Cleaning: Maintain a consistent cleaning routine, paying special attention to areas prone to moisture, such as drains and plumbing fixtures.

Proper Waste Disposal: Dispose of pet waste promptly and responsibly, minimizing potential attractants for sewer flies.

Campsite Hygiene: When staying at campsites, choose locations with well-maintained restroom facilities, and encourage proper waste disposal practices among fellow campers.

Seal Entry Points: Seal any cracks, gaps, or openings in your camper to prevent drain flies from entering. This helps create a barrier against potential infestations.
