Dear professional,
The below is a outcome of team suggestion, fully tried and tested spray. and we have been able to control 90% menace in our factory building sprayed in 13 acres of area. We have conistently won FIRST Prize in our TPM Activity competetion for 10 months, thereafter the menace was over.
RAW MATERIAL
KEROSINE ,PHENOL, WATER.
For preparation of 5 litre mixture: Take 3 liters of water+ 1/2 litre phenol and 1.5 litre of Kerosine. Shake the mixture for some time and store in 5 littre plastic can. spray the mixture on all points/areas . The mixture acts like a JALIM DAWA.
The efect last for 30 days. Hence, keep up the conistency of spraying every 28/29 days and the menace will be over.
