Valsad: Do not take this as a personal attack.
You policy is ignorant!
Take it from someone who, HAS, been bitten by a Rattlesnake - YOU do not want to be bitten by a Rattlesnake!
NOR... do you want to be responsible for allowing a poisonous snake to go on about its business and later bite someone else and have them go through the agony and damage a Rattlesnake bite will instill.
Reconsider your ill advised policy.
I kill every Rattlesnake I come across - period!
And I strongly recommend you do the same.
Hold into the wind
