Bugs

After bringing my chilis inside after the summer they all suffer from a bug that in Swedish is called "spinn" or "spinnkvalster", don't know in English but signs are spots on the leaves and spider-net like threads.

I had Aphids (still have on some) but fought those off by spraying with tobacco-water and soap-water.
That didn't help for the "spinn" though.

Also, no bugs, but two of my bonchis have a bit of mold on the surface of the soil.

Should I change the soil and keep spraying the plants?
Must I remove all traces of old soil from the roots, ie clean them very carefully or is it enough to wash of most of it?
Is there another/better method?

Thanks!

Those are called Spidermites in English. As far as i know there's only two good ways to get rid of them, chemicals or manual removal. Im sure google has the information about the chemicals used, However if its a minor infestation it should be enough to remove them manually. Take some paper towels and gently remove the webs and mites from the plants. Alternatively cut off infested parts if possible and needed.

Spidermites like a hot and humid climate, So i'd suggest you to stop spraying asap and hope for the Aphids to vanish without it :D


Edit: I myself had a minor spidermite problem earlier this fall, Luckely I saw them early on and it was about time to cut the plants down for overwintering anyway so all i did was cut the plant way back and gently threw the top of the plant in the trash :D I haven't seen signs of damage or bugs since :)

Yes, those are spider mites in english.  Neem oil can work, but you generally have to get poison specifically targeted for mites.

Another thing to remember is that the mite eggs are usually not affected by any poisons, so you'll need to treat the plant again in 8-10 days to make sure you get any stragglers that were still in the soil.  Might have to do that a time or two.

Could you reveal the source of the information above?

According to Wikipedia spider mites actually prefer a hot and dry climate, as opposed to a hot and humid one. Spider mites usually hide on the back of the leaves, thus spraying the back of the leaves with water (or with a pesticide specified to the insects in question?) should help you get rid of the problem.

Last summer I encountered a minor spider mite problem myself and it kind of solved itself. Maybe spraying with an insecticide called Raid helped a bit afterall even if it's not the "proper" way to deal with spider mites.

If I, however, were wrong about the climate issue, feel free to correct me.

You are correct, I got myself confused :)

Well, google gave me tobacco-water as one poison that should work, and soap-water as another way that kind of suffocates them IIRC.
But also several hits claiming that the soil should be changed.
Anyways, thanks for the help.

FWIW, after cutting down the plants to Bonchi and continued spraying with soap water, I think I got rid of the spider mites as well.

Very good news.

They could come back, but if it goes mite free for 10 days, you can safely assume the problem has been dealt with.

mohsart

Ah, so 10 is the magic number of days... I believe I've passed that but I'll continue spraying for a while anyways.
I also have the plants at three different locations so if they return they probably won't attack everything :-)
