F*cking ants!..
--really??... they
ate the seedling,...
...I gotta say GS, I've had them move in the pot because it's so nice in there, but never had them go termite on a live seedling! it's weird mate, maybe it's has an aroma that tricks them into thinking it's something else? Or something this species will just do,... in any case, [HASHTAG]#1[/HASHTAG] thing is to trace their entry point, and drop
right-now nukes on them, making that area lethal to be in,... I don't know what reg. pesticides you have, or strong repellent "garden safe" types, but in a limited area, like the seams or cracks they gained access through, laying down some real deal FO product is wise,... alternately, you could set the all on a large tray (or saucers), and lay down a bead of Tanglefoot or something like that-- a sticky "death moat"!
... I'm not sure about the cinnamon, I think the plant will be safe (I've used it in orchid pots to treat fungus) but maybe not repellent enough,... No matter what, don't lay down any sort of food bait, this will actually (by design) attract them for a time, then they die
en mass later as HemiSync mentioned,...(Boric acid in the bait)
.... :smoking: in other news,... the Burmese Diesel germ' failed, and since I was torn about it vs. Orange Hill Special, guess what took a swim the other day?
-- cracked a day later, and will be potted tomorrow! I want me orangey goodness
