Vasoline works by suffocating the tick, they breath through the skin (kinda). This takes a while, and should only be used if a tweezers or long fingernails are not around.
Matches and other chemicals make the tick back out, which also more importantly makes them sick and likely to throw up. And the risk of disease is much higher if a tick throws up in your blood stream.
Use a tweezers as close to the head as possible and pull gently until ticko gives up. Then burn the sucker with the white gas. Then send five dollars to BW and ten to me.
