There are heartworm “nosodes” available and other herbal heartworm prevention http://www.onlynaturalpet.com/products/Only-Natural-Pet-HW-Protect-Herbal-Formula/999068.aspx

Dr Will Falconer in Houston TX sells nosodes. His website is VitalAnimal.com

And there are also herbal parasite products as well. There are some at onlynaturalpet for you to look at too under “shop by condition” then “parasites”.

I use Halo Herbal Dip and Mercola Natural Defense Spray for mosquitoes and fleas.
