mite controlHi Jamie,

I have never heard of marigold pulp being used as an insect repellent. I know that many folks use it for medicinal purposes. Chrysanthemums contain a substance called pyrethrum that is an effective and commonly sold pesticide. Perhaps that is what you are thinking of.
Just about any liquid substance, including plain water, can be used to deter spider mites. Mites thrive in hot, dry conditions and do not like moisture. Soap and water is as effective as anything. The reason is not that soap is toxic to the mites, but rather the soap helps spread the water over the entire leaf surface. The real key to mite control is getting thorough coverage of all leaf and stem surfaces. If you miss a few of the tiny critters, they will live to breed and multiply. Thus, it is not so much WHAT you use, but HOW WELL you use it.
I have an article on safe pest control that I will send to anyone who sends their request to me at wcreed@Horticulturalhelp.com
Please let me know if you have any additional questions.
