Farmers spend lots of time and money getting crops off the field.

Once the crop's in the bin, it's important not to forget about it.

Brent Elliot is an entomologist with the Canadian Grain Commission.

He says it's important to protect the quality of stored grain from insects and mould.

However looking for insects, according to Elliot, can be difficult.

"They're very small, ranging from about 1mm to 5mm in most cases which is only about the length of a grain kernel," he said. "The best way to monitor for them is actually with temperature probes in the grain and looking for hotspots in the grain because what happens is when those insects start to reproduce, they start to produce carbon dioxide. They'll heat up the grain actually in those areas."

Elliot says to manage insects, you'll want to cool down the grain to 15 degrees Celsius using aeration. This may not kill the bugs, but it will keep them from feeding or reproducing.

He adds this method is also ideal for getting rid of mould, which can usually be spotted at the top of the grain pile in the bin.
