Spider Plant Worms
I returned from a trip out of town and saw that my spider plant, which has been outside, has dark spots on its leaves and little hole on the leaves. I also found little worms. They look like caterpillars on some of the leaves. How can I get rid of them to save the plant?

Various types of worms can affect plants. Those that cannot be picked off can be treated with products containing Bacillus thuringiensis (Bt), a natural bacteria that kill worms without harming plants. Neem oil may be helpful as well.
