Thanks for this info!!
I had always wondered why our mare never eats any of them while she seems to really like other flowers like thistle and chicory and farmer's friend. I am always looking for a good flea treatment for our cats, of course, diatomaceous works very well. Now I know to never powder them with Chrysanthemums!
You are quite welcome!
Yeah, I like using diatomaceous earth also. I do not have that much experience with cats but nitenpyram is safe for both dogs and cats. I do not know what it is made from but it will kill all fleas on an animal within twenty-four hours.
