@Hope Elisabeth 68 , that's crazy. Where was your EO bottle?
If in your basement, maybe mice or rats? or worse....
I think
@melinda48 suggested in a post not too long ago that mice really like soap and that she had to put screens or something on her storage racks.
I was dubious. But, after her comment, I realized some little white powdery shavings and little tiny black things that looked like 1/2 a piece of rice (or less) were mouse droppings and the white plastic where the mice were chewing away at the lid to my coconut oil (a new container I wasn't yet using so hadn't noticed.) The mice had managed to chew a line about 3" long and 1/16th of a inch wide on the lid. I don't know how long they had been working on it. I had soaps that were sitting in cardboard boxes curing and I had not yet put in a filing cabinet cuz I was running out of room. I guess they hadn't spotted my soap yet.....
As I looked around my basement, I realized that mice have been scampering all over my basement (little tiny mouse turds.) My husband put out some mice traps and sure enough, got some! (I hope that doesn't strike anyone as inhumane.)
So, possibly, critters are to blame.
