Entomologist Urges Leaving House Spiders Alive After Survey Found Them in 50 Homes

1 articles · Updated · The Independent · Jul 24

Summary

  • Matt Bertone says people should avoid killing spiders at home because most are neither aggressive nor dangerous and can help control indoor pests.
  • A visual survey of 50 North Carolina homes found spiders in every house, with cobweb spiders and cellar spiders the most common indoor species.
  • Those predators regularly catch nuisance insects, including mosquitoes, and some cellar spiders even hunt other spiders, making them part of the indoor ecosystem.
  • Bertone says bites are extremely rare, and even medically important widow and recluse spiders seldom cause serious harm; if needed, he recommends capturing and releasing them outside.
