Introduction: Rodents are the most destructive among all the vertebrate pests. Rodents cause heavy losses to crops as well as to stored food grains. Rodents contaminate food with their urine, hair and droppings causing large scale infestation. Also, rodents are carriers and reservoirs of many diseases. Chemical control of rodents is the most practical, popular, effective and economic method. Objective: This study was conducted in randomly selected different sized rice shellers in district Kaithal to devise an effective management strategy of rodents using chemical method. Methods: In the present study, fumigation treatment was done through celphos (aluminium phosphide) tablets for the management of rodents in randomly selected different sized rice shellers in dist. Kaithal. Results: A significant reduction in rodent populations by analysing through tracking markers census and bait intake census before and after fumigation. Significant control success was achieved resulting in 80.75%, 76.6% and 63.9% reduction in tracking marker census and 81.45 (g), 72.97 (g) and 60.42 (g) reduction in bait intake (g)/ bait box/ day in small, medium and small-sized rice shellers respectively. Conclusion: Phosphine fumigation and venting can be achieved to disinfest grains stored in silo bags and the fumigant can be applied using widely available aluminium phosphide tablets in a method that must not contaminate the grain with residues.
