5 Early Warning Signs Your Stored Grain May Have an Insect Problem

Why early detection matters


Stored product insects can cause significant losses through contamination, spoilage and reduced grain quality. Spotting issues early helps protect stock and reduce treatment costs.


The 5 signs to watch for


1. Hard or crusted areas in the grain If grain feels unusually firm and supports your weight, insect activity may be occurring beneath the surface.


2. Warm spots Grain should remain relatively cool. Areas that feel warm may indicate insect activity generating heat.


3. Insects on walls, ledges or bait stations Visible insects around the grain store often indicate a larger population within the grain itself.


4. Grain germination Unexpected sprouting can indicate moisture and environmental conditions associated with infestation.


5. Mould growth Mould and insect activity often go hand in hand, creating both quality and food safety concerns.
