(Making this a new thread so as not to hijack the 'Scent Barrier' post)

Recently ordered this to deal w/ possums in my yard (no broccoli for us this year) - seems to have worked - along w/ nightly floodlights on my tomato plants. Be prepared, tho - the stench is incredible - had to store the container in a tin to prevent the smell from escaping...

P.S. smell is not so noticeable when applied outside
