Spiders are one of the most-feared of all pests in the home that people want to exterminate. There are over 35,000 known spider species around the world, but only few are considered to be dangerous and 27 species are known to cause human fatalities There are more phobias about spiders than any other pest, and understandably so.
If you get bitten by the wrong spider – a black widow or a brown recluse – and you have a bad reaction to the venom, you can end up in the hospital. And yes, there have even been some deaths associated with spiders. Most spiders like moisture and are found in basements, crawl spaces, and other damp parts of home and offices. Others like dry, warm areas such as subfloor air vents, upper corners of rooms, and attics. They hide in dark areas.
