I say nuke the spiders with some strong systemic
insecticide. 1000 little white spiders would give me
the shivers. I know they are good and kill other bugs
but 1000....... time to start the chemical treatments
on the littl buggers.


Uh, and HOW would a systemic insecticide kill the "little
buggers" when a systemic requires the target critter to ingest
plant material and spiders don't eat plants?

Arachniphobia is treatable, Sam. Pesticide poisoning often
isn't.

But then, maybe we could get George W. to worry about these 1,000
spiders and he'd mobilize . . . something.

True but they are feeding off something, and that
something is probably eating the plant, maybe not but
if the systemic kills the bug they are feeding off
they will go away.. But jim is right if there is
nothing else there a systemic would be useless and do
more harm then good to the plant. I had a very
agressive white spider out on one of my wisteria vines
earlier this year which was amazing to watch spin its
web.

Nina.

Isn't this just what systemic insecticides were develped for?

Is there a reason we shouldn't be using them?

Thanks,

I considered telling you that indoor conditions are very bad for
spiders; there's very little food for them. I considered suggesting
that in spring, you catch each one and let it go outside.

But I decided against it.

While spiders are harmless, other arthropods may be building up
numbers on indoor bonsai this time of year. Everybody should take a
few minutes to look for scale insects. They can kill a plant very
rapidly- the symptoms are defoliation and branch die-back. Infected
plants may be sticky to the touch, because the scale insects exude
some of the sap they have ingested. The mature scale insect looks
like a wart or bump on the branch. They can be controlled to some
degree with insecticides, but their "armor" is fairly impermeable.
Horticultural oils will smother them, but coverage needs to be good,
and there's a danger of phytotoxicity. The easiest thing to do is to
dip a piece of paper towel in alcohol and rub off the scales. They
can't move- they're goners. A few weeks later, you can come in with
a pyrethrin or soap insecticide to kill the next generation of
"crawlers"; the tiny mobile juveniles.
