Common household remedies request
I can't keep houseplants alive because of the extreme temperature fluctuations from my woodstove, but my lack of houseplants is not the subject of this post. I have a friend, however, who does have houseplants, and those house plants seem to have mites on their leaves -- which have also become sticky. (The first plant I saw with this trouble was a peace plant, but this seems to be true for a spider plant as well.)
So, mites? Something else? And what's with the stickiness?
And how to get rid of whatever they are and it is? Neem oil?
