Do you have a recipe for killing dust mites? Thanks.
Tannic acid neutralizes the allergens in dust mites and animal dander.
There are some tannic acid powders on the market (check out Real Goods at
www.realgoods.com), but you can easily make your own with tannic acid-rich
tea, although you need to make sure to test this on the material you are
going to spray since tea stains. Make a very, very strong cup of black tea.
Strain, cool, and place in a spray bottle. Spray over problem areas.
