Thank you so much. It is good to know they are helpful to my plants even though they creep me out. I never knew those common black house spiders are poisoness. I see them all the time. Thank goodness for gardening gloves! Thank you again for your help. We saw a nickle size black small-legged spider with a white spot in its back and blue fangs this weekend. I was sure hoping it wasnt a whole bunch of them.
