While many of you will probably disagree, having spiders in the corners of your walls is not such a bad idea.
No matter how much you hate the idea, you will often see a spider and its web somewhere in your house. When you do, don’t kill it. Spiders can actually help you fight other insects that are not nearly as friendly.
How awesome is the idea of having a live “pet” at home that eats mosquitos and other annoying pests? Be gentle to your unwanted guests and they’ll return the favor.
