Used sacks can be immersed in boiling water to eliminate residue infestations [2] CABI recommends harvesting early before the borer gets into the grain.

[1][3] For cassava, infestation from the larger grain borer can be prevented by removal of any plant residue from the previous harvest if the pest is known to be in the area.

Leaving cassava roots in the ground for longer reduces storage time and chances for the borer to infest.

[1][3] Storing crops in airtight metal silos instead of bags and other easily accessible materials can also help prevent infestation.

This can be conducted by inspecting holes and cracks where adults can hide and using a box sieve with a mesh of 1 to 2 mm to separate the insects and the grains.
