Flighted Spongy Moth Complex (FSMC) is the current name used by authorities including the Canadian Food Inspection Agency for the group formerly referred to as Asian gypsy moth. Egg masses can be laid on vessel structures while ships are in regulated areas, then remain viable during an international voyage. Destination authorities may inspect or regulate vessels because larvae emerging near ports can establish invasive populations.
Why vessel-specific planning matters
Female moths may be attracted to vessel lighting during local flight periods. Egg masses can be deposited on exposed or sheltered surfaces including hatch coamings, deck equipment, container structures, light fittings and areas beneath bridge wings. Their colour and location can make them difficult to see against weathered coatings.
There is no single worldwide “FSMC season.” Regulated areas, specified risk periods, arrival requirements and acceptable certificates vary by destination authority and can change. Operators should check the current official rules for every relevant port call rather than relying on a general month range.
Pre-arrival vessel checks
- Review the voyage history. Identify calls in regulated areas during the authority’s specified risk periods.
- Confirm destination requirements. Check current certification, pre-arrival reporting and self-inspection rules with the relevant authority or agent.
- Inspect in daylight. Examine accessible external surfaces systematically, including sheltered and elevated areas that can be viewed safely.
- Document the inspection. Record date, location, findings, corrective action and the person or organisation completing the check.
- Escalate suspected evidence. Arrange competent identification and follow the destination authority’s instructions when egg masses or other life stages are suspected.
Handling suspected egg masses
Do not paint over suspected egg masses. Canadian guidance advises scraping them from the surface and securing the material in a sealed container. Removal and disposal must be controlled so material does not fall overboard, disperse around the berth or remain capable of hatching. Follow the applicable authority’s current instructions and the vessel’s safety procedures.
Certification and port-entry consequences
Some destination authorities require certification for vessels that have visited specified regulated areas during defined risk periods. The issuing arrangements and timing depend on that authority. A vessel arriving without the required evidence may face offshore inspection, delay or other regulatory action. Certification does not replace the crew’s continuing obligation to keep the vessel free of egg masses after inspection.
FSMC inspection support in Singapore
PestCare can support vessel operators with systematic onboard pest inspection and documentation while a vessel is in Singapore. Before confirming an FSMC attendance, the team will review the voyage and destination requirement so the scope and documentation match the operator’s needs. The destination authority remains the final source for entry and certification requirements.
Common questions about FSMC vessel requirements
Does one FSMC certificate cover every destination?
Not automatically. Authorities define their own regulated areas, risk periods, certificate requirements and validity rules. Confirm acceptance with the next destination or appointed agent before relying on an earlier document.
Can a crew self-inspection replace an official certificate?
Only when the destination’s current rules allow it. Self-inspection is good practice even when certification is required, because egg masses can be deposited after a formal inspection and before the vessel departs the regulated area.
