Several years ago we almost killed ourselves trying to rid our home of ants. Of course this is a slight exaggeration, but our health issues flared for nearly a year after spraying our kitchen and ultimately led us down the path of diet experiments. We now know better than to turn to chemicals first.
Between the two of us, a couple of issues that seemed to be linked to the insecticide was extremely heavy periods that lasted nearly a year and hives covering the whole body that just wouldn’t go away for weeks even with antihistamines. It only calmed down later doctor prescribed prednisone (steroid).
This reminded me of my aversion to bug repellent or mosquito killers as far back as I can remember. Family used to tease me that I was a bug in a past life. Does salicylate (as nature’s pesticide/ insecticide) sensitivity or multiple chemical sensitivity have a connection to repulsion toward strong scents and insecticides?
