Signs of Granary Weevil
What to look for🔎Signs of infestation and damage
Live insects or larvae in grain, flour, pulses or spices, webbing or clumping in stored material, an off/musty smell, and small exit holes in packaging or grain kernels.
How Granary Weevil is controlled
Integrated approach🧪Control methods
Control relies on strict stock rotation (FIFO), sealed storage, regular inspection of incoming material, and — for active infestations — fumigation or heat/cold treatment by a licensed operator; residual insecticide treatment of storage structures (never the food itself) helps prevent re-infestation.
