I have a boat dock with decking and metal underneath to let water run off the top deck. Wasps go in between the decking and build nests underneath and I am unable to hit them with any kind of spray. I read in the catalog about dusting with Drione when they are in the cracks of wood. Would that be a solution or can you suggest something else?
