A tick will not move without its head. This is one way to know if a tick was completed removed from the source. A moving tick still has its head.
I have a tick in a bottle that I caught 8 months ago. All he needs is moisture to stay alive.
I have placed a tick under water for 2 days and the tick survived. I witnessed death at around 3 days. Other subjects died at 2 days (48Hrs). I did not do controlled studies but will be more exact on my next entry. Dennis
If the tick is not carrying a disease, there is nothing that would put someone's life in danger. If the tick is carrying lime disease or Rocky Mt. Spotted Fever, etc. ; it would need to be treated in a couple of days, the sooner the better.
