For an exterior structural application for spider's, paper wasps, etc., what's the residual longevity of the product?
Essentria IC3 Insecticide Concentrate can be expected to last about 6 weeks around a structure. Longevity depends on exposure to sunlight mainly. Areas not in direct view of the sun can last longer. Areas exposed to sunlight for much of the day can be much less. UV light is the most degrading factor to residual longevity.
