American House Spider
The American House Spider, or Parasteatoda tepidariorum (also known as the common house spider), is an arachnid similar in size and body shape to the Black Widow. Its bite has a similar toxin to the venom of the Black Widow, but much less potent. These spiders like to make their webs near human dwellings, such as in attics and open doors. A single female American House Spider can produce up to 17 egg sacks in her lifetime, with each sack containing from 100 to more than 400 eggs.
