I just started using organic molasses outdoors, as I've decided to use a higher dose of that so that I can reduce the qty of SWEET & Bud Candy carbs that I'm mixing and save money. No problems with attracting animals & insects. Can't even smell it considering all the other ingredients it's mixed with, anyway.
My girls are pretty big, so I'm going with a heavy dose more like a tablespoon per gallon rather than a teaspoon. Depends how large your girls are and how much they are feeding.
