Thank you so much for your suggestions. If I may address your post

I've had good indoor crops of aphids on my lettuce,

I am not sure if lettuce would work too well since I would have to
replant after it dies next year. I am not too familiar with nasturium.
What kind of plant is it? (ornamental? edible? flowe? etc) and would
it be available at my local HomeDepot? The guys down there are not all
that scientific, so would they know what nastrurium is??? (does it have
a "common" name?)


sweet pepper plants.

I am a bit confused by this. Are you referring to bell peppers? (they
kind you find at your local store which come in green, red, yellow,
etc?) If so, I was actually considering that plant as well, so your
vote of confidence is most appreciated!

Room temperature and humidity are loved by aphids.

Done! hehe


If your area has not had frost, you might still find aphids here and there. In my
yard, they hide in the curled underside of leaves.

frost isn't really a problem here in Los Angeles (this late in October,
and the weather was 95 today!!!). I inspected the rose buds today in
search of some aphids, but couldn't find any. Oour roses are under
direct sunlight most of the day. So I guess its too dry for the aphids
to like it...there is always the neighborhood roses (time to go on an
aphid-kidnapping rampage LOL)

Thanks again for your reply!
