2.      Use of light trap for controlling adults moths. 
3.      Ploughing of land after harvesting. 
4.      Digging trench surrounding ingested field and killing them. 
5.      Application of biological control. 
6.      Spraying of microbial insecticides. e.g. Bacillus thuringiensis. 

B) Chemical control of Jute Hairy caterpillar 

1.      Application of Sevin/ Diazinon/ Diginol 60 EC @ 3 mL/ L of water. 
2.      Application of Ripcord/ Cymbush/ Fenon 10 EC @ 1 mL/L of water.
