The female black widow will produces an egg sac containing 250-750 eggs that hatch in two to four weeks, depending upon temperature.
Black widow spider venom affects the nervous system. Because the bite itself is relatively mild, some people may not even realize immediately that they were bitten. The venom causes pain in the lymph nodes. Other symptoms of a severe bite include nausea, elevated blood pressure, sweating, tremors and increased white blood cell counts.
The wound may appear as a bluish red spot, surrounded by a whitish area. Both male and female spiders bite, but adult females produce the most severe bites. An antivenom serum is available through a physician, but it must be administered soon as possible after the bite occurs.
