I sprinkle borax power on the carpet we leave it overnight and vac the next day

Borax is NOT a safe benign chemical.

Borax can be absorbed through the skin and lungs and cause severe
abdominable cramping and gastric disturbances in susceptible
individuals. No kidding.

When you vacuum the carpet, a lot of the powder goes right through the
filter bag and becomes airborn in a fine dust which penetrates deeply
into your lungs.

Open the windows on a breezy day and wear an appropriate respirator.
