You Shouldn’t Kill Spiders in Your Home, According to a New Study


In a survey of 50 homes in North Carolina for complete arthropod fauna of the indoor ecosystem, researchers found high diversity with an estimate range of 24-128 distinct families of arthropods per house. Spiders are crucial part of the nature as well as the indoor biome. While people tend think their houses are safely insulated from the outdoor environment, many species of spiders can be found inside.

The researchers discovered that each house was home to spider, with cellar spider and cobweb spider being the most common species. These spiders enjoy indoors, thrive, and reproduce more spiders as well as catchers their prey, especially smaller insects. Cellar spider also leave their web and raid the webs of other spiders, mimicking prey to eat those spiders.

In general, most spiders are predators, consuming everything trapped on their webs and regularly catch nuisance pests or disease-carrying insects such as mosquitoes. Interestingly, a species of jumping spider is commonly found in African homes that feeds on blood-filled mosquitoes. It indicates that killing a spider at home not only takes life of arachnid but also removes an important predator from the indoor ecosystem, according to the researchers.

The venomous nature and long protruding legs may make spiders look dangerous, but the venom is very weak to cause any issue to the human, if the fangs can pierce the human skin at all. Many entomologists themselves become a prey to arachnophobia, and they overcome the fear by observing and working on these interesting arthropods. And, for the fear of spider attacking them, one must not kill a spider every time they see it in the house.

The researchers said that the spider prefer to avoid humans and not actually attack them; humans are more dangerous to them than the other way. Spider bites are extremely rare. However, there are certain medically important species such as recluses and widow spider, even their bites are not common and rarely cause severe issues.

Arthropod fauna in the indoor biome has significant impact on the daily lives of human society and its diversity extends far beyond commonly recognized species. More research on the indoor ecological dynamics is required for better understanding the potential health implication of such organisms that thrive and evolve in such close proximity to human beings.
