Delta Dust Insecticide - Questions & Answers

Yes, Delta Dust Insecticide is effective for killing roaches. Delta Dust Insecticide would be best used in the wall voids. You cam remove the faceplates of your electrical outlets and dust inside the wall voids. However, if you have a roach infestation we would highly recommend our Roach Control Kit #2. This professional kit includes 1 packet of Demon WP Insecticide (which makes 4 gallons of finished solution) for spraying the outside perimeter of the home and inside underneath appliances, behind cabinets, under toilets and sinks, etc. You'll also get 4 x 35 gram tubes of Invict Gold Roach Bait Gel--one of the best roach baits on the market. Invict Gold can be applied up high in the kitchen in the corner of cabinets and in cracks and crevices in kitchens and bathrooms. The bait contains a slow-acting poison that attracts and kills feeding roaches, who also spread the bait to other roaches by contact or by sharing food. Finally, 20 Gentrol Point Source stations provide an IGR (Insect Growth Regulator) that will stop roaches from laying eggs, helping to halt the infestation. The combination of an IGR with roach bait is a highly effective roach control strategy that is widely used by pest control professionals. Demon WP must be applied with a 1 gallon pump sprayer, like the Chapin 1 gallon sprayer.

The difference between Delta Dust and Alpine Dust are the active ingredients. Delta Dust is waterproof and contains deltamethrin. Alpine is a reduced risk dinotefuran dust. Both will last many months in undisturbed voids and treat many insects.

The Delta Dust would be an excellent option to use with the B&G Electric Duster for attics, crawlspaces or other large areas.

Delta Dust is meant to be used in cracks and crevices and inside wall voids.  It is not labeled to apply out in the open like on a window sill where people could easily touch it.  It is meant for places people cannot easily access it, like underneath appliances and inside wall voids.   

Delta Dust Insecticide is actually the most recommended dust for cicada killer wasps holes as it is 100% waterproof so will still work when wet.  

When using insecticide dust such as Delta Dust you should apply it using a hand duster but you will be required to get to all of the areas where these pests can enter. The B&G M1150 duster can give you a little further reach in some areas if needed.

Yes, you can apply Delta Dust Insecticide in furniture under the cushions, at furniture joints, and behind fabric tacking. We recommend using a hand duster such as the B&G Bulb Duster 1150 when applying insecticide dusts. Be sure that you do not apply dust directly on skin contact areas. Excess dust can be wiped up with a damp paper towel.

Delta dust can be applied under a deck but it can be washed away by running water. You may want to consider using a concentrated product such as Talstar P that can be applied with a sprayer and will be rain fast.

The shelf life of Delta Dust is 3 years form purchase date. It should still be effective, as long as it was properly stored in a dry, moderate temperature area.

How quickly Delta Dust Insecticide will kill a cicada killer wasp is dependent on how much dust the wasp picks up on its body and the size of the of the insect. Typically dust can kill an insect in as little as an hour or as long as 24 hours or more depending on these factors.

Yes, Delta Dust can be applied to all the outlets in your kitchen, as well as in your home. It is not necessary to wear gloves or a mask. Make sure that you are doing a light dusting in these areas so that the pests will walk through it and dry out. Since it's in the wall voids, it will not affect your food.

A 1lb bottle of Delta Dust is enough to treat 1,000 sq feet. When applying, the duster should be filled only halfway - no more than two-thirds full. This allows for adequate air space to create the desired air/dust mixture prior to application. If there is too much dust in the duster, clumps of dust on treated surfaces may result, leading to overapplication. Please refer to our Article "How to Get Rid of Yellow Jackets" before treating for safety tips and proceedures.

You can use Delta in the cracks and crevices in and around your baseboards. You should not apply it on the outside of the baseboards because it will get moved around just through normal daily activities (walking past, vacuuming, sweeping, etc) and will not remain in the areas where you applied it. Bedbugs usually start dying within 1 week of coming into contact with areas treated with Delta dust. Please note that you should not use Delta Dust alone to combat bedbug infestations as it is slow acting. Please checkout our bedbug kits for our product recommendations.

Delta Dust Insecticide will not react with boric acid dusts but applying too much dust to an area can make insects avoid it.  If you can see the dust so can they, we would not recommend applying both in the same area.
