Ms. Vickers, did you ever get an answer to your original question? Got a lot of comments I see, none of which address your concerns and those that feel we're trying to rid ourselves of a natural pesticide, think again. The 'frog apples', or 'toadstools', as some refer to them, which accumulate all over the front door, and porch is not only an eyesore, but a health concern. There must be a way to re-direct the little guys to someplace else. They're fun to look at, from a distance. Let me know. Thanks, email@example.com.
