Cashew Nut Shell Liquid (CNSL)

Cashew Nut Shell Liquid (CNSL) is very effective in termite control. To prepare 10 litres of 5% CNSL emulsion, 500ml of CNSL and 50g bar soap are required.

Slice the bar soap and dissolve in 500 ml of water. Pour 500 ml of CNSL slowly and stir vigorously to get a good emulsion.  Dilute this one litre solution by adding 9 litres of water to get 10 litres of 5% CNSL emulsion.
