Alpine Dust could be used in place of DeltaDust but with roaches baits are the most effective part of treatment or using a spray such as Phantom that works like a bait in that it has a transfer effect back to the colony. All the sprays/dusts you have used only kill those that contact a treated area or that are sprayed directly (pyrethrin/PBO). It can take weeks/months to completely eliminate a roach infestation especially in a commercial setting where food/water could be available, so proper santitation and good housekeeping are a key part of treatment. We have a guide here that can help as well.
Alpine Dust is labeled for general bees. If this product is applied in areas where carpenter bees are, it will make the area unhabitable for them to live and dry them out, killing them as well. Be sure to only do a light coating of dust to ensure that they do not avoid it.
Please take a look at our Carpenter Bee Guide for tips on how to treat and prevent carpenter bees in the future.

Alpine dust is a contact and residual powder insecticide for crack and crevice, spot and void treatment. Alpine Dust has two active ingredients for quicker kill broad-spectrum use: Dinotefuran and Diatomaceous Earth. Dinotefuran is a newer non-repellent active ingredient that the EPA has granted Reduced Risk status for public health use. Dinotefuran is part of the insecticide class neonicotinoids, neuro-active insecticides that are modeled after nicotine. Dinotefuran is a central nervous system inhibitor that takes effect after insects ingest it. Diatomaceous Earth is a completely natural insecticide made of crushed freshwater diatoms (basically tiny algae fossils) directly from the earth. When insects contact or ingest diatomaceous earth, the scratchy surfaces cut through the waxy coating on the insects’ exoskeleton, causing dehydration and eventual death.
Alpine Dust is labeled for carpenter ants and would be an excellent addition to your treatments.
Per the product label: "For ants, apply to ant trails, in openings around doors and windows and other places where ants enter premises. Direct contact with dry dust is required to be effective."
