depend on the pet
Yes, you can die from it, but if you get medical attention quickly, you probably won't.
A black widow is not harmful to the evironment but can be very harmful if it bites someone. Any person who gets bitten will go into cardiac arrest and possibly die or death will occur without medical action immediately after.
If a black widow bites you it will inject its poison into you. The skin in the area of the bite will become red and may turn black and die, along with some of the muscle. You may also get very ill from the venom and develop kidney or liver problems. You could even die. It's best to see a doctor immediately if you are bitten by a black widow.
I hope that if you have been bitten you are going to see a doctor before you find out.
They die
You are probably defining a false black widow.
No. After killing her mate, the female black widow must live on afterwards to lay the eggs.

This depends on your age, health and whether your are allergic to the venom. If you are not allergic, and are in good health, it can take up to 48hrs for the venom to kill you in normal conditions. They are actually not as dangerous as many think; the reason they are considered a dangerous spider is more the fact that they often live where humans do, and therefore people are often bitten. The last death from a redback bite was in 1979, due to development of antivenom. There are 14 deaths ever recorded.
