3.I know it may be hard to convince you,but let me try:Don't kill the next spider you see in your home.
Why?Because spiders are an important part of nature and our indoor ecosystem—as well as being fellow organisms(生物)in their own right.
People like to think of their living places as safely isolated from the outside world,but many types of spiders can be found inside.Some are accidentally trapped,while others are short-term visitors.Some species even enjoy the great indoors,where they happily live out their lives and make more spiders.These spiders are usually secretive,and almost all you meet are neither aggressive nor dangerous.And they may be providing services like eating pests—some even eat other spiders.
My colleagues and I conducted a visual survey of 50 North Carolina homes and found that every single house we visited was home to spiders.The most common species we encountered were cobweb spiders and cellar spiders.They simply eat anything they can catch.Spiders regularly capture annoying pests and even disease-carrying insects—for example,mosquitoes.There's even a species of jumping spider that prefers to eat blood-filled mosquitoes in African homes.So killing a spider doesn't just cost it its life,it may take an important predator out of your home.
Spiders are not out to get you and actually prefer to avoid humans;we are much more dangerous to them than vice versa.Bites from spiders are extremely rare.Although there are a few medically important species like widow spiders and recluses,even their bites are uncommon and rarely cause serious issues.
If you truly can't stand that spider in your house,apartment,garage,or wherever,instead of killing it,try to capture it and release it outside.It'll find somewhere else to go,and both parties will be happier with the outcome.
But if you can
stomach it,it's OK to have spiders in your home.In fact,it's normal.And frankly,even if you don't see them,they'll still be there.So consider a live-and-let-live approach to the next spider you encounter.
