Ecology Works does the job on indoor air
Ecology Works' Dustmite and Flea Control is a stain-free, non-toxic and odorless EPA-registered borate compound that kills mites and fleas for up to six months, the company said. It can be applied as a spray or via hot-water extraction to bedding, upholstery and blankets.
Ecology Works' Anti-Allergen Solution is a plant-based, stain-free, non-toxic liquid the company says neutralizes protein allergens on contact, including dust mite feces, cockroach droppings, and dander from dogs and cats. It contains no tannic acid or benzyl benzoate.
