Spiders do poop, and their spider waste usually looks less like a neat pellet and more like a small dark stain. If you are asking how do you spiders poop, the short answer is that their waste comes out in a concentrated form that often dries into a spot, smear, or tiny splatter. You can…
Spiders make webs by turning liquid silk into strong threads. They then shape those threads into a trap or shelter. If you have ever wondered how spiders make webs, the short answer is that a spider uses spinnerets, silk proteins, and careful body movements to build a web piece by piece. A spider web is…
Spiders kill by combining speed, restraint, venom, and smart hunting tactics. They trap or chase prey, inject venom, and then liquefy the victim for feeding. Understanding how spiders hunt helps you identify house spiders in your basement or figure out how to get rid of spiders around your home. Most spiders do not threaten people,…

The male uses his pedipalps to move sperm into the female, and the female can store it until she is ready to fertilize her eggs. Males do not use a penis during reproduction. Instead, they rely on a sperm web, paired…
Spider vision helps them survive, not read fine details. Most spiders use their eight eyes to notice light, shape, and movement, so they can spot danger or catch prey fast. If you want to know how spiders see, the short answer is that they detect motion very well, even if their view is fuzzy. A…
