I don’t see why it would. FB probably have a receptor for a particular chemical that brassica produce and home in on this. This process won’t be affected by putting a strong smell on top. Worth a try though, nothing ventured, nothing gained.

Mine went out today on the plot and the greenhouse ones were potted into their builders buckets.  I’ve had tumblers out in containers for a week or so now and they are growing away like crazy, the weather is predicted to stay as it is - warm, showers, some sun and everything would have needed potted on next week. 

I reckoned it was time to go for it 

They got into my greenhouse in late winter and ripped open and devoured a bag of bird seed lol, they are smart and I would assume they wont eat anything that harms them, unlike me lol

Jacket potato, cheese, coleslaw and corned beef (special request from himself).

Slow cooked beef stew and chunky mixed veg.
