I don't know why but I keep getting little spiders in the house, like a couple had sex and babies hatched. Not only that, but in the bathroom I have found like 5 large spiders in like a month and have no idea how they got that big as there are no other bugs that I see. The pic shows the usual size I have been finding, but just in the bathroom. The jar is a mushroom jar. I place it over the spider, slip a rile card under it and voila'! one caught spider. Then I dump them outside. I know most people kill spiders, but maybe there is a reason I never see any bugs in my house.
