Joseph from Philadelphia writes
CB-80 Aerosol should not stain any surface its applied to, however we nor the manufacturer can test for all surface applications. We would recommend testing in a small inconspicuous area first before treating in a wider area where you have the pests emerging. Unless you are spot treating only behind the siding, we would recommend using a concentrated product you mix with water and spray in that area instead since aerosols are not going to hold up to the outdoor elements as well and are used more for spot treatments to flush insects out as a contact kill. Cyzmic CS would be a great option for residual insect control outdoors.
