Sarpa Dosha is different from Kalasarpa Dosha.
This Sarpa Dosha effects a person even after his death. Improper or no cremation, death through accident, murder, suicide, poisoning, body tearing into pieces in a bomb blast, cremating without complete body parts (main parts not found), cremations done very late by strangers but not blood relatives etc.
While Kalasarpa dosha is mostly hereditary and its effects are seen only during Vimsottari dasas of Rahu, Ketu and others planets associated with them, Sarpa Dosha has no specific time limit.
Kalasarpa dosha has simpler remedies but Sarpa Dosha needs to be carefully examined and judged in a horoscope and its remedies are not easy.

Reasons for Sarpa Dosha or Naga Dosha in Horoscope
Vedic Astrology gives multiple reasons why Sarpa dosha is formed in a horoscope.
Main reasons are occult or black magic activities done by ancestors and self made mistakes in previous lives.
Sarpa Dosha or Naga Dosha does not mean just killing snakes or reptiles.
Even killing a unborn child (abortion) will have same effect as sperm is considered similar to snake (its shape and crawling method).
Ketu controls life after death (right from when death starts in present life till entering into a womb for next life).
To determine Sarpa Dosha in a horoscope, above symptoms (effects) can be helpful and then personal horoscope along with horoscopes of family members will be helpful.
In mahabharata, Sage Astika saved Sarpa race from being extinct during Sarpa Yagam.
One needs to read and recollect that episode is useful for those effected by Sarpa Dosha.
