    To prevent spiders from entering your home, start by inspecting the exterior of your house. Remove any items that could attract spiders, such as wood piles, dense vegetation, and long-stored objects, as these areas provide ideal hiding spots for spiders. Also, clear a perimeter of at least one foot around your home, keeping it free of vegetation, tree branches or leaves, and stored items. This one-foot barrier helps deter spiders from making their way inside your home.

    Are they dangerous or poisonous?
    Community Answer
    Usually not. But a female spider is very protective of her eggs, and may bite if she feels threatened, which will cause a large and painful bump.

    I have been watching a female nursery web spider in my garden for weeks. She has been carrying her egg sack for longer than a week. How much longer will it be until the babies hatch? Will she die after the babies leave?

    The time of death after a hatching depends on the species of nursery web spider. As for how long until the eggs hatch, she will create her enclosure for the eggs around a day or two before they start to emerge from the sac.

    No; it stays with its egg sac and can be very aggressive in its protection.

    Hello, I have a large spider in my kitchen. I see them quite often and they don't have webs. This one has spun a ball of silk around itself in ceiling corner and is agitating back legs. Any ideas?

    It may be getting ready to lay its egg sac? Without more information, this answer cannot be final but it seems most likely.
