How in the world do you get rid of spider mites on my fragile house plants? Thanks!!
We have found the best way to treat spider mites is with neem oil. Not only is it effective, but it's also quite safe. This article should help you: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
When I bring plants home from the store, one will lose its leaves. Nothing left! I know it's some kind of bug, but I don't know what to spray them with. It doesn't happen to all of them, just one or two. Can you help me?
Treat the plants with neem oil when you bring them home. That will take care of most bugs that could be on the plant. Here is more information:

I would also soak the pots of all the plants. Sometimes the rootballs get dried out and without a soaking, the actually repel water. If the store let the rootball dry out, the plant will die if the soil is not soaked.
We have a plant here in the office that is covered with brown or rust colored spots on the top side of each leaf. There are just a couple raised brown spots on the underside of each leaf. The top side is also sticky. Could this be aphids? If it is, can the plant be treated or does it have to be disposed of? I am assuming this is contagious to the other plants.
It is most likely scale (which is a lot like aphids). It can be treated, and yes, in the meantime it is contagious. These articles will help you:

What are the procedures of cleaning my grow room to prevent further appearance of spider mites?
Non organic things can be wiped down with rubbing alcohol or bleach. Plants and other organics can be treated with neem oil. These together are pretty effective in eliminating all the pests and eggs.
I have a broad leaf indoor plant that I potted a few months ago. I am now seeing little white worms, about 1/4 inch long, coming out from the drain hole underneath the pot. What are these things? Are they bad for the plant, and if so, how do I get rid of them? Is there a treatment I can buy to avoid re-potting?
