January 5, 2026 – A Mosiller electric fly swatter, model FSAG-01US, has been implicated in a fire incident, reportedly igniting while plugged in for charging. A public fire department fire investigator concluded the fly swatter was the probable ignition source, noting multiple similar complaints in online reviews.
Product Details
Incident Overview
On December 11, 2025, an incident report was filed detailing a fire involving a Mosiller electric fly swatter, model FSAG-01US. The consumer had purchased the device from Amazon.com on November 1, 2025. The fire occurred while the fly swatter was actively charging. A public fire department fire investigator conducted an on-site investigation and definitively ruled out all other potential ignition sources, concluding that the Mosiller electric fly swatter was the probable cause of the fire. The report further highlighted a critical detail: multiple reviews for the product on Amazon.com describe similar circumstances where the fly swatter caught fire during the charging process, suggesting this may not be an isolated incident.
Safety Concerns
The incident involving the Mosiller FSAG-01US electric fly swatter presents severe safety concerns for consumers:
- Immediate Fire Hazard: The most pressing danger is the potential for fire. A product igniting while charging can quickly escalate, leading to significant property damage and posing an immediate threat to life and safety for anyone in the vicinity.
- Burn Injuries: Fires, even small ones, can cause severe burn injuries to individuals attempting to extinguish them or who are in close proximity to the ignited device.
- Property Damage Potential: A device catching fire while plugged in can ignite nearby curtains, furniture, carpets, or other flammable materials, leading to extensive property damage. If unattended, such an incident could result in a catastrophic house fire.
- Who Might Be Affected: Anyone owning or using this particular model of electric fly swatter is at risk. This includes individuals, families, and even businesses that might use such devices. Given that charging often occurs overnight or when devices are left unattended, the risk is heightened as a fire could start without immediate detection.
- Electrical System Risks: A defective charging circuit or battery can not only lead to fire within the device but could potentially stress household electrical outlets or wiring, though the primary risk here appears to be the device itself.
- Unattended Operation Risk: Products that ignite while charging are particularly dangerous because charging often happens when consumers are asleep, away from home, or not actively monitoring the device.
What Consumers Should Do
Given the serious nature of this incident and the corroborating evidence from multiple online reviews, consumers who own a Mosiller FSAG-01US electric fly swatter should take immediate action:
- Stop Using Immediately: If you own a Mosiller FSAG-01US electric fly swatter, cease all use immediately, especially charging. Do not attempt to charge the device again.
- Unplug and Isolate: If currently charging, carefully and safely unplug the device. Move it to a non-flammable surface, away from combustible materials.
- Check Your Product: Verify if your electric fly swatter is the Mosiller brand and model FSAG-01US. This information is typically found on the device itself or its packaging.
- Do Not Dispose in Regular Trash: Do not discard lithium-ion batteries or battery-powered devices in regular household trash due to fire risks at waste management facilities. Contact your local waste management facility for proper e-waste disposal instructions.
- Report Incidents: If you have experienced a similar incident, or if your Mosiller FSAG-01US fly swatter has shown signs of overheating or malfunction, report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at www.SaferProducts.gov. Detailed reports are crucial for safety investigations and potential recalls.
- Retain Product (If Safe): If possible and safe to do so, retain the product and any associated packaging and receipts. This can be important evidence if a recall is initiated or if you need to pursue a claim.
