Really just want to be sure it won't stain the dryvit if sprayed onto it.
PT 221L Residual Aerosol should not cause staining on any regular outdoor surfaces. This product does have oils in it, so if you are concerned about any specific sensitive materials, then we recommend testing a small area first.
Be sure that you are locating and addressing any moisture issues if you need to treat for springtails. We have more information in this article regarding management of this pest.
