Why should you never squish a spider?

You should not squish a spider for several reasons related to hygiene, effectiveness, and ecological benefits, though squishing does kill individual spider. First, squishing a spider, especially with bare hands, can create mess with bodily fluids that stain walls, carpets, and surfaces, and may cause allergic reactions in sensitive people. Second, some spiders carry bacteria and squishing can spread germs, though risk is low, washing hands after is important. Third, squishing female spiders that carry egg sacs, particularly wolf spiders that carry egg sacs and babies on back, can release hundreds of tiny spiderlings that scatter and spread throughout house, worsening infestation. Fourth, spiders are beneficial predators that eat pests like flies, mosquitoes, cockroaches, and other spiders, so killing them removes natural pest control and may increase other pest problems. Fifth, most house spiders are harmless and not aggressive, biting only when threatened, and squishing is unnecessary when humane relocation is easy, place container over spider, slide paper underneath, and release outdoors. Sixth, squishing can be inhumane, and many people prefer humane methods. Better methods to handle spiders include relocation, regular vacuuming of corners and under furniture to remove webs and eggs, sealing cracks around windows and doors, reducing clutter, and keeping outdoor lights off to reduce insect prey that attracts spiders.
