they eat insects like flies, and they help us.
No. There is no need. Spiders hatch fully armed and prepared.
Spiders need shelter as well as humans do. That just happens to be in your house.
Yes, but there is no need.
Yes, all species of spiders need water to survive.
Spiders need food (insects), water, shelter (usually a web or hiding spot), and a suitable environment with the right temperature and humidity levels to survive. They also need to avoid predators and hazards to stay safe.
It is not a question.
Spiders don't feed their babies with milk. Baby spiders get their feed by themselves catching small insects and don't need mother's care.
Spiders need/use venom to paralyze their prey so there is no struggle. Thus, the spider has an easy meal.
you need to get it checked out if it hurts
Spiders do not eat grass. They are carnivorous predators that typically feed on insects or other small animals like flies, mosquitoes, and other spiders. Grass does not provide the nutrients spiders need to survive.
Well, female mosquitos do, as they need the protein and iron. But no spiders (that come up in search, anyway)
They bite people because they need food to eat.
