The grains get spoiled or infected due to environmental changes, excess use of chemical and lack of storage houses which, results into losing their nutritional values. Therefore, it is necessary to check the nutritional status of grains time to time since the nutritional factors also depend on upon the environmental temperature and moisture present in the grains. These are few of the major reasons responsible for fungicide and insects growth in the grains, which directly attack the kernel of the grains and fill the kernel with their eggs, pupa and larvae. The present paper shows the control of moisture and disinfestations of food grains with respect to selected power level and time. The paper presents the disinfestations of pulse beetle in selected pulses like whole mung bean, rajma and red lentil and kills the insect and their whole life cycle at the surface and kernel level. The domestic microwave is used to treat the pulses at different power levels 900 W, 720 W, 450 W, 270 W and 90 W for 30 Sec, 60 Sec and 90 Sec exposure times for disinfestations and to measure the moisture loss in pulses. And the acquired results of moisture further validated by the standard moisture meter DMM8. The moisture level of the whole mung bean varies from 7.80% to 7.22%, of rajma varies from 10% to 9.5% and of red lentil varies from 9.40% to 8.89%. And the protein contents of the pulses are calculated by the standard Kjheldal method, in which protein content of whole mung bean varies from 22.03% to 21.4%, of rajma varies from 22.5% to 22.3% and red lentil varies from 22.25% to 21.7%. All these samples are monitored for 90 days to analyse the mortality rate of the pulse beetle insects and their life cycle. Finally, it is observed that with controlled microwave energy the achieved mortality rate is approximately 95% in pulses
