does anyone know of a list of grub control products that shows which are most and least harmful to the beneficial soil life besides the targeted pest? least harmful grub control product? least harmful selective herbicide? a list would be great, but if anyone knows the most enviro friendly products speak up. thanks. and i know there are natural and organic pest controls, but sometimes they don't work as well, plus this isn't the organic forum. so, please only EPA regulated pesticides.
