With that said, it could work, but it would only kill the "Exposed Adults and Larvae". It will not kill insects that are insect of food, grains, bags, under pallets, inside walls, cracks, crevices, etc.
You really need to determine exactly what species of moth or grain beetle you are dealing with. It doesn't sound like a mealy moth at all, but some species of grain moth.
The only way to kill all insects in this manner is to "fumigate" the warehouse which has to be performed by a licensed fumigator. Products used for this are usually Methyl Bromide or Vikane. This is where a gas is shot into the warehouse and kills everything in a matter of hours. This may or may not be practical, but again, has to be done by a licensed fumigator. It's also fairly expensive and can result in a lot of "downtime" while it is being done.
The only thing you can do is to try and keep everything as clean as possible. If the insects are in the soybeans, there is not much you can do. Inventory rotation becomes critical as the point.
A solid pest control program or spraying program on a regular basis will not eliminate the insects inside the soybeans. Again, sanitation and inventory turn are about the only thing you can count on to reduce the problem.
Keeping floors swept, vacuumed, bleached, and sprayed will certainly help. Accumulations of soybeans under pallets, along walls, or in wet areas will only provide a breeding source. These issues must be addressed every day.
There is no magic bullet or chemical other than what you are doing. Sanitation and inventory turn are key.
Hope this helps. If you have any other questions, I am here to help.
