Is a black and white spider in japan poisoned?

Question:

i found a black and white stripped spider in my laundry room.
i was just wondering if it was poison is.... i live in okinawa japan.

Answer:

Japan has a hitch hiker spider from Australia called a "red back spider" the male of the species has a white marker on the back where the more dangerous female has a bright red marking.
Generally they have untidy webs found under outdoor chairs ,tables. when the male and female mate, the female kills the male.
If it is a red back spider I recommend you get pest control onto it ASAP. A mere $100 can save your life if not allot of pain.
