There over 35,000 species of spiders with about 3,000 existing in the US. Certain types of spiders can be found most anywhere, usually in dark secluded areas. Most spiders spin webs to hide and catch prey. Most spiders live for about a year or less, but the lifespan for many can be longer. Some tarantulas can live for 25 years and even longer.
Friend or Foe
Despite a bad reputation, spiders are really our friends, although they can become pests. They balance nature which benefits our ecosystem. In the garden, spiders dine on insects that are harmful to plants. They also kill mosquitoes which transmit life-threatening disease and flies that carry filth and harmful bacteria.
Although some people actually welcome spiders into homes to keep pesky bugs in-check, there are better ways to prevent insects from infesting homes. Besides, spiders can really scare family members and guests. Spiders belong in yards and gardens where they provide the greatest value to nature.
