If there is enough heat, this may speed up the life cycle development of the weevils and cause the stored grain products to cake, mould or even germinate. This makes your food products unsafe to eat.

Females bore holes in grains to lay eggs, which will then hatch inside. Once the larvae are fully developed into adult grain weevils, they will bore a large hole to exit the grain.

If you suspect grain weevils are contaminating your food, you’ll want to act fast to prevent them once and for all. Contact Allstate Pest Control today for expert advice and treatments.

Signs of a grain weevil infestation

• Large holes in your grains or stored products
• Grain weevils are 3-3.5mm long, oblong-shaped, red-brown coloured with pointy snouts
• White, dusty droppings

Thoroughly clean, wipe and vacuum the affected areas, paying attention to cracks
and crevices.

Ensure the storage area has proper ventilation to reduce moisture, which provides ideal larva incubation conditions.

Where possible, reducing the temperature of stored grain can also help slow down
weevil activity.

If you’re still battling to handle grain weevils from your pantry, it’s best to call Allstate and speak to one of our stored product pest technicians for professional treatment options.
