Spiders
Spiders belong to a subgroup of terrestrial arthropods (aka arachnids) whose main prey are mites, ticks and scorpions. A spider has four pairs of legs, eight eyes and unsegmented abdomens. If you find wings or antennae on a crawler, what you have instead is an insect. Outside of Antarctica and in the oceans, spider habitats are found everywhere in the world.
Why you shouldn’t kill spiders
Putting arachnophobia aside, allowing spiders to coexist with you indoors can be a big plus. According to Katelyn A. Kesheimer, Ph.D., assistant professor and extension specialist at the Alabama Cooperative Extension System, Auburn University, “Spiders are harmless and provide free and excellent biological [pest] control.”
Wolf spiders are commonly found crawling along the ground in leaf litter or may even make it into the house. You shouldn’t kill them because, Kesheimer says, they’re harmless and feed on small insects inside and outside your home.
“I don’t know that most people would want spiders around,” she says. “But at the very least, if we can learn to live with them, we may fear insects less and appreciate the critters around us.”
