Large American roaches live in crawl spaces. Will this work if I spray through all the vents in the foundation?

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?

Answer:

Archer IGR should not be sprayed through vents or other similar areas. You can apply only as directed on the label.
