If you use those as decoration, and not really bonsai wise. Easyest is to get a replacement. But be sure no other plant in house still have them. Or you face the problem again.

Let's continue the nitpicking (well... not too long, I will stop after this).
You are right. However, there are diseases that affect house plants (there's no such thing as house plants, you might want to add), more than it affect outdoor plants. The reason is, as I wrote, the different environment. I have never seen aphids on my indoor plants, nor have I seen scale. I have had them on my outdoor trees. I've never seen spider mites on my outdoor trees. I have seen them on indoor plants.

So, I do believe there's a difference and I'm pretty sure that experts on house plants know more about it than I do.

There are no indoor trees, no indoor plants and certainly no indoor pests. It all comes down to conditions. If the condions is there, they Will come.

I have had spider mites on cucumber in my greenhouse, on cactuses indoors and on pines outdoors. The solution for all Three occations was the same.

That's.... what I said, right? And conditions indoors are different then the conditions outdoors.

Also, don't tell the kelderzwam I had there are no indoor plants :D

Kelderzwam (källarsvamp) is not active on this forum, so no risk :).

Also, fungi is not member of the family plantae which is normally considered when taking about plants.

I promise you, no more posts from me in this thread ;)
