 your bug killers, the weed killers, all that stuff, do not keep this in a building that is attached to your home. This should be outside in a carport, in a shed, something like that, because those things do off gas, and it will work its way back into your home. And what's funny, and it's something that I've noticed with Caroline, and she told me this, and she's done it multiple times, she can go through an air quality test and see what chemicals are underneath your sink.
