The mythology I remember reading is that if you make tea with 2 cigarettes worth in boiling water, and then drink the water, it's a guaranteed fatal dose! So it's pretty strong stuff. There actually used to be a commercial insecticide based on this, called Black Leaf 40. I haven't heard of it in a long time, not sure if it's still around...

I might try six pillars with equal spacing and height as their thickness. Put them toward the outside edge of the top of the chimney so there is just enough inner/upper surface to properly support the smallest pot you want to use.

A tea of tobacco is the only thing I know of that will drop large numbers of aphids dead, and quick! Nothing else works for me...not soapy water, not D.E. My rutabagas have them bad right now and I'm out there rubbing and smushing every week. I've been around some kids that grew it years ago....it's pretty easy once you get the very fine seeds to come up.
