As we "installed" our tractor on Wed., we killed a couple black widows, and yesterday my dd said she found one by the house. Then my neighbor called and said they are having a real problem with them behind their shed. I'm assuming that a chicken would just eat them, but I am worried about my young kids and the baby. Besides cleaning out any old wood and keeping the grass mowed and neat, is there anything else we can do to get rid of them? My neighbor would rather avoid heavy chemicals due to her pets and small children, if possible. Dh said we should advertise a showdown between the black widows and brown recluses and see if they obliterate each other.
