GRAIN WEEVIL, Sitophilus granarius



Grain weevils are approximately 3-4mm long and dark brown in colour. A serious pest in grain and other hard cereal products, larvae and adults will feed on the grain.

Damage is easy to identify by exit holes in the grain made by emerging adults. White tainting of the product and heating of grain can lead to germination and mould. Temperatures can reach a point where the insects will die.

Traps should be used to monitor infestation and good hygiene methods are essential. Insecticides should be used to treat harbourage points, cracks and crevices etc.
