Probably the most
prevalent of storage moths in UK flour handling premises, this
species is a significant pest, and responsible for considerable
spoilage due to its presence and activities. Larval silk may
lead to blockages in process machinery. |

Complete metamorphosis life cycle. Adults
emerge in the spring and mate. Females may lay up to 200 eggs over 2 weeks.
Larvae are active, secreting and depositing large amounts of silk within the
micro-habitat. After 5 or 6 moults, they move upwards toward wall / ceiling
junctions where they secure themselves for pupation and emergence after
diapause. |

Good hygiene, harbourage
denial and quarantine of inbound stock are recommended. Any
insecticidal treatments that may be applicable should be timed for
adult emergence to achieve maximum effect. Residual sprays should
be targeted at resting places and harbourage areas.
Monitoring traps can be used as an indication of emergence. |
