Fly nuisance in south Llanelli

Carmarthenshire County Council is currently investigating reports of elevated fly activity affecting parts of south Llanelli, including the Seaside and Morfa areas. Investigations are ongoing and officers are examining several potential sources in order to establish what is contributing to the increase in fly numbers. 

No. Investigations remain ongoing and no definitive source has been identified at this stage.

Public Protection officers have inspected several locations and are gathering evidence from across the affected area. Samples of flies, larvae and pupae have been submitted for analysis and further site inspections are continuing. 

The investigation is considering a number of potential sources. These include the AMG Resources facility, Dŵr Cymru's Northumberland Pumping Station and other sites within the wider area. Officers are taking an evidence-led approach, and all reasonable lines of enquiry are being assessed. 

To date detailed inspections of the Trostre Household Waste Recycling Centre and the Dŵr Cymru Northumberland Pumping Station identified no evidence of significant fly activity, poor housekeeping, waste leakage or conditions likely to contribute to the current infestation.

There is currently no evidence that the estuary is responsible for the unusually high levels of fly activity being reported.

Estuaries are natural environments and support a range of insect species. However, the type of widespread nuisance currently being reported is not, in itself, evidence that an estuary is the source.

The Council has received reports linking the issue to the nearby estuary, but investigations have not identified evidence supporting this as the cause of the current situation.

There is currently no evidence that long grass is responsible for the scale of fly activity being experienced.

While flies may rest on vegetation, long grass itself does not generally provide the type of conditions required for large-scale breeding of the common nuisance flies that are the subject of this investigation.

Many fly species require suitable breeding material such as decomposing organic matter, waste, sludge or other nutrient-rich environments.

The Council continues to assess all potential contributing factors as part of its investigation.

Actions undertaken to date include:

• Responding to resident complaints.
• Visiting affected locations.
• Inspecting potential source sites.
• Monitoring fly activity across the area.
• Collecting fly samples and related evidence.
• Working with NRW, Dŵr Cymru and other partners.
• Providing updates to residents and elected members.
• Undertaking environmental cleansing activities where appropriate.
• Deploying fly traps in appropriate locations to draw them away from residential and commercial premises where possible.

Investigative work remains ongoing.

NRW is the environmental permitting authority for the AMG Resources site and is responsible for regulating compliance with environmental permit conditions at that facility.

The Council is sharing evidence with NRW and working closely with them throughout the investigation. NRW has undertaken inspections of the site and continues to monitor conditions. 

Fly populations can be influenced by a range of factors and may travel significant distances from where they emerge.

Before regulatory action can be taken, evidence must demonstrate that a site is contributing to the problem. This requires detailed monitoring, inspections and, in some cases, specialist analysis.

The Council's investigation is focused on establishing the facts rather than making assumptions.

The Council has been carrying out monitoring work at a number of locations, including schools, businesses and residential areas. This information is helping officers understand the extent and distribution of fly activity across the community.

Warm temperatures can accelerate fly breeding cycles, allowing populations to increase more rapidly. Certain weather conditions may also influence how far flies travel and where they congregate.

Weather is therefore one of several factors being considered during the investigation.

While the increased number of flies is causing considerable nuisance and distress for residents, the Council has not identified any wider public health emergency.

The Council recognises the impact that the situation is having on local communities and is continuing to investigate the issue and take appropriate action where required. 

Residents may find the following measures helpful:

• Keep doors and windows closed where possible or use fly screens.
• Ensure food waste is stored securely and bins are kept closed.
• Clean up any pet waste promptly.
• Avoid leaving food uncovered.
• Use fly traps or fly papers where appropriate.

These measures may help reduce the number of flies entering homes, although they will not address the underlying cause of the wider issue.

The Council will consider requests for support on a case-by-case basis, particularly where residents may be vulnerable or significantly affected by the nuisance. Residents experiencing particular difficulties are encouraged to contact the Council. 

Fly numbers typically increase during warmer weather.

However, the level of activity currently being reported by many South Llanelli residents is greater than would normally be expected, which is why a formal investigation is being undertaken.

The investigation aims to determine whether the current conditions are simply weather-related, linked to one or more local sources, or influenced by a combination of factors.

The Council understands the frustration being experienced by affected residents. However, the cause of the current fly nuisance has not been established and the Council is unable to comment on whether any future claims may arise.

Any requests relating to insurance or compensation would be considered in accordance with the Council's normal procedures.

Residents are encouraged to continue reporting fly nuisance to the Council via the Council’s contact Centre on 01267 234567 or alternatively via e-mail at publicprotection@carmarthernshire.gov.uk. Information provided by residents helps officers map affected areas, identify trends and support the ongoing investigation. 

When reporting an issue, please provide:

• Your address.
• When the problem started.
• The level of fly activity being experienced.
• Any photographs or videos, if available.

The Council will continue to provide updates through its website, social media channels and local elected members as the investigation progresses. Further information will be published when significant developments occur.
