Includes tiny snouted weevils, narrow grain beetles, hairy larvae and small moths. Identification often requires the product and damage pattern.

Some species develop inside whole kernels while others feed externally in flour, dust or damaged grain.

Dry foods and commodities including cereals, pulses, seeds, spices, tobacco, nuts and processed products.

Eggs are laid in or near food. Warm storage conditions can allow overlapping generations and rapid population growth.

Live insects, webbing, holes in grain, powder, cast skins, clumping, heating and adults near lights or windows.

Infestations contaminate products, reduce quality and can cause significant commercial losses.

Prevention

Confirm the organism before selecting control measures

Remove food, water and shelter where practical

Seal or manage access points and harbourage

Use monitoring and a site-specific IPM programme

Professional support

Arrange a site-specific assessment with PCAMB.
