It’s an insect-fighting Catch 22: many insects love hiding or nesting in moist areas, yet many insecticides are less effective (or not effective at all) when exposed to moisture.
DeltaDust solves that problem. It claims the title as “the world’s first and only 100% waterproof insecticide dust.” That makes it a great choice for those damp or wet areas that insects love so much. The makers of DeltaDust say that nothing short of direct application of running water will disturb it. It’s also easy to apply into cracks and crevices (it can be applied using a hand duster, power duster, paint brush or various other methods).
DeltaDust is effective against a long list of insects, including ants, cockroaches, fleas and ticks, and spiders.
