Oh man, flying aphids? I hope I never get to see them.

Get a large flat pan, fill it with water, put a rock or something in it to put the pot on, and elevate the pot so that it does not soak up water. This isolates the pot and the tree from the ants because the ants can't swim.

... Have you never had flying aphids? Aphids with wings, My indoor infestations always start with one flying into the room and nesting in one of the plants.

I have not had these.

I have never figured out why bugs are so much of a problem inside but pretty much disappear a day or so after moving the plant outdoors.

Infestations is more likelly to happen on weak trees. Indoor trees are almost allways weak. And outdoors wind,rain and predators make the life as an aphid much harder.

Yup. Peak summer when plants are too full, there is a phase during which they aphids go to sexual reproduction, and then the adult phases have wings too, so they can move to other plants easier.

I wonder if that is a European variety of aphids. I have never seen that, and we have plenty of summer. My experience is that insect problems virtually disappear once the flowering trees have stopped flowering., except for ants crawling up the stands and making nests in the pots.
