Facts About Mansion House

That may not help with severe cases of arachnophobia, but fear and respect aren’t mutually exclusive. The more we know about these misunderstood housemates, the less fodder we have for misguided phobias. In hopes of clearing house spiders’ name, here are eight interesting facts that might persuade you to put down the shoe, pick up a magnifying glass and give peace a chance.

Still, deferring to spiders on a camping trip isn’t the same as sharing our homes with them. Does a spider’s evolutionary seniority really give her free rein over habitats built by and for humans? Maybe not, but ousting spiders from any house is a herculean task. Not only are they stealthy and stubborn, but they’ve been living with us for a very long time. In fact, many house spiders are now specially adapted to indoor conditions like steady climate, sparse food, and even sparser water.

Not everyone who’s afraid of spiders hates them, leading many people to try non-lethal eviction. Perhaps the most common strategy involves trapping a spider in a cup and releasing it outside, where it can presumably return to its natural lifestyle. This is a noble sentiment (and often requires quick reflexes), but as Crawford explains, it may not achieve the desired result if the arachnid is a true house spider.

House spiders typically colonize new buildings via eggs sacs attached to furniture or building materials, but sometimes outdoor spiders also wander inside. Many of these are spiders that eschew idn poker online webs in favor of active hunting, like wolf spiders, and may be seen scampering across floors or walls. If you release one of these outside, you might actually be doing it a favor. Just be sure to let the right one out.

One of the most abundant house spiders is Parasteatoda tepidariorum, aka American house spider, which is native to North America but now found around the world. Measuring 4 to 8 millimeters long, these yellowish-brown spiders have a tall, round abdomen and two rows of four eyes. They build tangled webs, often both outside and inside a building, so evicting them may be harmless — and futile. On the bright side, they have relatively mild venom and bite humans only in self-defense.

Steatoda grossa, aka cupboard spider, has similarly expanded far beyond its native Europe, including North America and Australasia. Varying in length from 4 to 11 millimeters, this spider is known for messy webs that contribute to indoor cobweb buildup. It’s also one of several Steatoda species known as a “false black widow” because people commonly confuse it with that highly venomous spider. Not only does it lack the black widow’s red hourglass, however, but its bite is more like a bee sting.

Instead, he adds, they probably just got stuck while looking for water. “House spiders are thirsty creatures living in a very water-poor environment, and any that venture near a sink or tub with drops of water in it will try to reach the water, often by climbing down a wall. Once in the slick-sided porcelain basin, they are unable to climb back out unless a helpful human ‘lends them a hand.'”

Spiders in general don’t deserve their scary reputation. They rarely bite people, and even when they do, most species’ venom causes only moderate and short-lived effects. That’s true for the vast majority of house spiders, which have no incentive to bite anything they can’t eat unless they think it’s a matter of life or death.

“House spiders prey on insects and other small creatures,” Crawford writes. “They are not bloodsuckers, and have no reason to bite a human or any other animal too large for them to eat. In any interaction between spiders and larger creatures like humans, the spiders are almost always the ones to suffer.”

Sealing potential entry points may not affect house spiders, since they don’t sneak in from outside, but it could limit incursions by other spiders. And if it also prevents insects from getting inside, it may indirectly reduce your house spiders by limiting their food supply. Various myths suggest house spiders are repelled by osage orange, horse chestnuts, or even copper pennies, but Crawford is doubtful.
