A lot of people have a deep fear of spiders, however, a top Entomologist has explained why you should never kill spiders if you see them in your home.

Despite the popular belief that most human indoor dwellings are safely insulated from the insect world, there are still many that find their way inside.

Some get accidentally trapped, while others are just short-term visitors.


Arachnids are secretive creatures, almost all you will meet are neither aggressive nor dangerous, another reason why choosing to kill spiders isn’t really a good option for your karma.

Spiders are not out to get you and really choose to avoid humans; we are a lot more harmful to them than vice versa. Bites from spiders are extremely uncommon.

Although there are a few clinically important species like widow spiders and recluses, even their bites are uncommon and hardly ever cause severe problems.

It’ll discover elsewhere to go, and both celebrations will be better with the outcome.

However if you can stand it, it’s OK to have spiders in your home.

In fact, it’s regular.

And honestly, even if you do not see them, they’ll still exist. So think about a live-and-let-live technique to the next spider you experience.
