Pest ControlQuestion 187 of 319
An employee opens a 5 lb bag of flour and notices fine silky webbing along the inside of the bag and small caterpillar-like larvae. This is most consistent with infestation by:
a.Drain flies
b.Stored-product pests such as Indian meal moths or grain beetles
c.German cockroaches
d.Norway rats
Explanation
Stored-product pests — including Indian meal moths, grain weevils, and flour beetles — leave silky webbing, larvae, and shed skins inside bags of flour, rice, cereal, and other dry goods. The product must be discarded, the storage area cleaned, and remaining stock inspected. Rotating stock (FIFO) and sealed containers help prevent recurrence.
