Growers should monitor grain temperature regularly – not cooling during winter may be due to pest activity heating the grain.
Spear thermometers kept continually in each bin when checked regularly for any fluctuations in temperature can identify problems. In addition, check regularly for pests on the floor around bins and on outer bin walls, and between and in the folds of any sacks of grain. If possible, turn the bin contents during the winter to prevent the build-up of mites in the moist upper layer, and make use of probe traps and pitfall traps to monitor for pests.
