Thank you, that is cool!
I am planning on how I can apply this. one way is I can just flood the rocks and use some sticky stuff at the stems, but if I want total eradication, I guess that I will have to do changes in the design like a perfect lid that prevents aphids from running off. If I then flood just to the level of the lid for 5 minutes, this must be a close to perfect way to boiling them aphids;
If nothing else it will be interesting.
smoking this stuff is helping me imagine. I think that I found a great cheap foolproof way to do this. I can just use PVA glue with a paint brush all around the walls . This stuff is sticky, food grade, and dries up in a good 15-30 minutes. I can then just flood it to the level of the glue for 5 minutes, let them cook, and the glue will catch the ones that are trying to escape. I think that this could work, .
Please post tons of pictures as soon as you get under way.
