Swift Moth Larvae (Ghost Moths, Hepialidae)
Large soil-dwelling larvae feeding on roots and crowns, causing severe wilting.
Swift moth or ghost moth larvae are large, pale caterpillar-like soil pests found in turf, ornamentals, and container-grown crops. They feed at night on roots and crowns, causing rapid wilting and collapse. Control relies primarily on entomopathogenic nematodes (Steinernema carpocapsae and Heterorhabditis bacteriophora), ideally applied during warm soil conditions. Cultural reduction includes removing dense thatch and improving drainage.
Biological Controls for Swift Moth Larvae (Ghost Moths, Hepialidae)
The species below are examples of beneficial organisms commonly used against swift moth larvae (ghost moths, hepialidae). Recommendations are based on published biological control information and practical IPM experience. Always confirm suitability for your crop, growing system and local conditions before use.
Steinernema carpocapsae
Environment: outdoor
Temperature Range: 10.0 – 25.0°C
Rate: 0.5–1 billion nematodes/ha in high water volume
Frequency: One main treatment; repeat if monitoring remains high
Targets soil-dwelling larvae; apply to moist soil in dull conditions.
