Hi Marina,
Two pages lay out complete plans to control these pests without danger:
1. Non-Toxic Flea Control, and
2. Drug Free Heartworm Prevention
If you want to further understand these approaches, you can use the search boxes that appear at the bottom of most pages, like the home page. Just type in a word, like fleas or heartworm, and you'll be presented with a list of every page that I've written that contains these subjects.
