Well dried paddy at about 12 to 14 percent moisture can be stored safely for several months to a year if you keep it dry and protect it from storage pests like rice weevil and grain moth. Dry the grain fully before storage, use clean dry bags or bins, stack them on wooden pallets away from walls and damp floors, and keep the store ventilated and rodent proof. Neem leaves mixed in traditional bins, and proper cleaning of the store before filling, help reduce pests. For larger quantities, sealed storage and approved fumigation by a trained person controls infestation, but follow safety rules strictly. Check stored grain every few weeks for heating, moths or live insects and re-dry or treat if needed.
Drying properly first is everything. The year I stored slightly damp paddy, weevils ruined a few bags by summer.
In Madhya Pradesh I store paddy as whole grain in husk rather than rice, because the husk protects against weevils much better. I mill only what I need for a month or two at a time and the rest stays clean.
One caution: clean the empty store and seal cracks before filling, because weevils survive in old grain dust in corners and reinfest the new lot. I sun the empty bags too, and that cut my pest trouble a lot.
In Odisha I keep my paddy in an airtight metal bin filled right to the top, since with little air inside the insects cannot build up. A well-sealed full bin kept my grain clean far longer than loose bags in the open.
One tip from Maharashtra: I lay a few dried neem leaves between the bags and keep the store cool and shaded, because heat speeds up the weevils. Checking once a month for any moths flying out let me act before a bag was spoiled.
