If I can't crawl into my crawl space, will this be effective if I use a garden sprayer and mist into all the foundation vents on our home? From my understanding, the roaches do not need to make direct contact with an IGR - they just need to be in close proximity. So, if I spray in the vents, will that be close enough to be effective?
Archer IGR should not be sprayed through vents or other similar areas. You can apply only as directed on the label.
