DELTA DUST containing deltamethrin is the world's first and only 100% waterproof insecticide dust, so it works in the wet and damp places that insects love. Nothing short of running water will disturb it, making Delta Dust an ideal crack and crevice treatment. Delta Dust should be applied with a bellows hand duster (sold seperately) which allows you to easily apply the dust in hard to reach areas. One application of Delta Dust will keep on killing insects for up to eight months.
Delta Dust should not be the only product used in the fight against bed bugs as it does not kill quick enough. For best results, use a contact kill such as Sterifab or Bedlam in addition to Delta Dust.

DELTADUST Application Tips:
- DeltaDust is intended for application with a hand or power duster (Actisol DPA or similar equipment), with a paint brush or by other suitable means, for hiding and runaway areas and other places where insects are found.
- In living areas, apply in such a manner as to avoid depositions on exposed surfaces or introducing the material into the air. In the home, all food processing surfaces and utensils should be covered during treatment or thoroughly washed before use. Exposed food should be covered or removed.
- To apply insecticide directly into cracks and crevices, use a bulbous duster or other suitable equipment. Apply lightly and uniformly to infested area. Pay particular attention to: cracks and crevices, service ducts, floors and ceilings, wall voids, around electrical and telephone fittings and equipment, around water and sewer pipes, under and behind cabinets, refrigerators and sinks, around windows and door frames, along baseboards, in attics and crawl spaces. The amount to be applied will vary with the site but should usually be in the range of 2-3 grams of DeltaDust per square yard (or 0.5 lbs per 1000 square feet).
Proper Dusting Tips:
- 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 of the product and messy spills.
- Between each squeeze, the duster should be shaken slightly to get dust floating inside the unit.
- When applying dust into cracks and crevices and on surfaces, gently squeeze the duster to ensure the application of very thin layers of dust. When dusting correctly, you should barely be able to see the dust emerging from the tip of the duster.
- Before relaxing your grip on the duster, pull it away from the surface or crack you are treating to prevent sucking up lint, moisture or debris. Small amounts of these items will eventually cause lumping and/or clogging of the duster.
- Place several pebbles or small ball bearings in your duster to keep the dust agitated and ensure than any clumps are broken up prior to application. Also, always keep the screen inside the duster in place as this is designed to help maintain a fine dust consistency.
- When treating around electrical outlets, use dusters fitted with plastic or fiberglass spouts, or place a small section of rubber hose or plastic tubing over the metal tip to avoid contacting electrical wires. These tubes will also enable you to reach around corners and beneath cabinet voids that would otherwise be impossible to treat.
- Carry a small brush and a damp cloth. These can be used in the event that dust accidentally drifts out of cracks and crevices and onto non-target areas. Use the brush to push excess dust into cracks, and use the cloth to wipe up.
- Do not apply dust to baseboards.
- Apply dust carefully and judiciously so it does not travel to areas where it might represent a hazard. Prevent food contamination by not applying dust to where it could filter down onto food or food areas after it is applied. Also, be aware of any air currents that could transfer dust to containers or other objects, leading to food contamination.
- If the applicator is to apply any kind of dust for extended periods of time, he or she should wear a respirator approved by the National Institute of Occupational Safety and Health (NIOSH).
- When using high-volume or high-pressure equipment to apply dust in attics or sub-floor crawl spaces, wear a NIOSH-approved respirator. Also, shut off fans, air conditioners, and hot-air heating equipment if necessary. If the dust is combustible, put out all flames and pilot lights, and shut down all spark-producing equipment in the treated area to avoid explosions.
- In general, do not place the tip of the duster in a moist location or allow the duster to sit in moist environments as it will absorb water and become clogged. Clogged dusters can be cleaned by scraping out the spout with a piece of stiff wire.
- Always follow the label when using DeltaDust.

By Jennifer on 09/28/2008
The siding on my home is red cedar and apparently it is a favorite treat for CARPENTER BEES. They were making terrible holes in the siding like perfectly round bullet holes, and then the woodpeckers would come along and peck at the wood making long channels so they could reach the carpenter bees behind the wood. It was a mess. My painters filled the wood with BONDO and caulk and wood filler...but that did not stop the bees. Over night they bored right through ALL of the products and the fresh paint. I called three exterminators but everyone told me they would spray and I would have to pay again and again in a few months because you could not kill them with just one spray. I BEG TO DIFFER! I found Delta Dust and I puffed it into the fresh new active holes that the bees made after painting. Within 24 hours I picked up over thirty dead bees on the ground around my house (I have small dogs and I did not want them eating dead poisoned bees). By 48 hours the count had risen to over SIXTY dead bees... and there are NONE flying around the holes, or siding any more! DELTA DUST IS A MUST for carpenter bees. It worked GREAT!!!!

We have ordered Delta Dust in the past to control Brown Recluse Spiders. It is amazing! We had our house sprayed for several years, twice a year, and we would still have Brown Recluse Spiders. I found your website and ordered Delta Dust from you, and our Brown Recluse Problem has been cut in half. We continue to apply the Delta Dust and see great results. Thank You!! P.S. We use it as a perimeter treatment and also in wall voids, in the attic space and under the house. I am very thankful for your product as we were killing approximately 5 spiders a week before we used the Delta Dust. I still find them now and then, especially when the dust has been washed away outside.

This stuff saved my sanity and my marriage!
By A in San Diego, CA. on 06/23/2011
My husband picked up bed bugs in a four star hotel while away for work in the UK. We know that's where he got them because he'd seen one inside his suitcase the day he returned and he was asking me if I knew what it was. I didn't and we just thought it was "a bug" not realizing that a within a week we'd both be covered all over our abdomens and arms with the nasty bed beg bites. We vacuumed, cleaned, tossed bedding, dry cleaned etc but they kept coming back. Until I did my research and discovered Drione dust. Follow the instructions to a T and you'll succeed in eradicating those evil, disgusting pests. We also did the "Vasoline" around the feet of our bed which helps keep them from climbing up the bed from other areas of the home. It was HELL. HELL!! But we beat them. We also bought the air tight mattress and box spring protectors. They work! It's all good, it all helps. Good luck!

Amazing againsts stink bugs!!
By Marilyn on 03/28/2008
You have probably saved my home. I have an infestation (almost overnight) of STINKBUGS. Very difficult to get rid of. Got the Delta Dust - amazing - within just a few day they were gone . It states the product last for 6 months but it hasn't been that long, however just having relief from the constant pest is great. I must say I did not have much luck with the duster - difficult to spray. Ended up using a turkey baster, sorry guys. But I really encourage any one with a problem with Stink bugs to get this and get it FAST!

I use a hand duster to puff Delta Dust into wall voids by inserting the duster underneath my baseboards. It will kill whatever is living inside the walls or travelling along the perimeters of the room. Also used Suspend SC (liquid version of Deltamethrin) with a gallon sprayer on top of the dust for an added punch-- this duo of Delta Dust and Suspend SC has given me great results in getting rid of earwigs, spiders, ants, and fleas.

This is an AMAZING product. Only had to use very little. I used it w/the B&G bulb duster 1150. The Bee's were gone instantly. Make sure you wear a respirator. It's important!!!! Can't say enough good thing about this product.

This is amazing for Bed Bugs
By Jade in Chicago on 03/09/2013
I love this dust. I live in Chicago and I use this as a crack, crevice and perimeter treatment after spaying Fenvastar with Gentrol and this is amazing! The other products worked great for residual kill of the bed bugs, with them lessening after the first treatment...but this helped me the most because it helped me find out where these little nasties were coming from in my bedroom. I live in between 2 adjacent apartments that have both been confirmed as infested (FINALLY-after I took a bed bug on a pin to my landlord) The bed bugs from the apartment on the right were coming in through the front door, and were confirmed, but then I started seeing them coming up my bathroom sink which is connected to the infested apartment on the left (tenant bug bombed). So I sprayed my FenvaStar under the sink and problem solved....or so I thought. So, after I dusted the perimeter, there was a crack in the wall that we shared by the bathroom. You should have seen these bugs running from the crack......so next step is to caulk it to slow the flow of new 6 legged tenants from infested neighbor on the left, but it it wasn't for this dust helping me to find the source, I would have been in bed bug hell forever! Although it was fun watching them run then go into convulsions after hitting the dust! :D Thank you so much again for carrying these products! So much money has been saved because I will have to treat for the remainder of the year and it has also helped to educate my landlords about how to properly treat bedbugs in their buildings(landlords current PCO is LAZY, 5 minute spritz and he's in and out, but they are now aware of that issue and are taking proactive steps so it may get better, they just needed to be educated on how to select a PCO specialized in bed bug removal for large buildings).

Gets rid of bedbugs fast!
By Martha in Houston, TX on 08/16/2011
I researched bedbug treatment on the internet, and found that different types of treatment, like Pinesol and bleach were recommended. However, none worked in the least. But then I remembered that I had used the delta dust for fleas a while back, so thought I'd check to see if that would do the trick for bedbugs. Delta Dust did indeed advertise that bedbugs were also treatable. Using only a little dust, primarily at the baseboards (since I had read that that's where they like to hide), from that moment I have had no more problems! Very highly recommended.

It works but takes at least two weeks
By Jay in Paramus, NJ on 06/13/2011
I got a whole colony of ground nesting bees in a small garden right next to the entrance where our family go in and out the house. There were probably 20 holes in the small garden. When the sun was high and weather was dry, they would be flying around that area. I was certain that one of our family member would got stung sooner or later. I ordered the dust and a duster (Centrobulb Duster), and started using it right away. Although the recommendations suggest us to apply it in the evening when we were sure the scouts have gone back to the nests, I found that I could not see most of the nests in the evening because the outside was dark (and there were too many holes to keep track with). I ended up applying the dust in the early morning when there was enough light to see all the nests and when the bees were still inside their nests. After a few days, I still saw bees flying around (but in a significantly fewer number). I applied the second time. A few more days later, I started flattening some of the nests. But soon I had to back off because I heard buzzing sound near my ears. I applied the dust for the third time in the next morning. I noticed that the nests that I had flattened didn't re-open. This gave me hope. A few days later, I decided to flatten half of the nests. This time no bee bothered me any more. The next day I found that none of the flattened nests were re-opened, and I flattened the rest. None of the nests are active ever since. This stuff works! I will apply a layer of mulch over that area, and that will be the final chapter of this event.

Works for scorpions!
By Neil on 04/28/2011
Delta Dust has finally made our yard scorpion-free! We've been using Cy-kick which has helped tremendously, but only after using the Delta Dust in all the cracks, crevices and borders have we been completely free of scorpions. And you definitely should use the centrobulb to dispense it. We even put a barrier of the dust at the base of the house and along the bottom of the perimeter concrete wall. When we first put it down, we found a couple of scorpions that were mostly dead after treading through the powder, but now we don't find any at all when we check at night. Great product!

When I moved into our new home, I was shocked to see that there were bugs already there, roaches. A friend of mine told me about Delta Dust, but I wanted to do research myself. With the positive reviews I bought it and thank god I did. I have not see a pest in my home since. Thanks for Delta Dust!!!!! I definitely will recommend buying.

By Chris in Lansing, Michigan on 09/17/2010
I highly reccomend this. I had a nest of wasps between my aluminum siding and the backerboard of the house. I tried aresol insecticides which were pretty useless. All I ended up with was a pile of dead wasps but they were breeding faster than I could kill them. I blasted this stuff in the crack they were coming and going out of and the next day they were gone. I don't know what happened to them; probably a dead nest behind my aluminum siding but isn't that what we're going for here?

Good for ants and general coverage
By Richard in San Jose, CA on 06/25/2010
I've been using EcoDust (nice smell!) but switched to Delta Dust given the good results I got from the granules last year. It's an easy dust to distribute, no clumping, and with a good duster provides good coverage. In the short time I've had it out, it's been very effective against the larger black ants (these are not carpenter) that have been coming into the house. I've been using the hand duster to blow this dust into cracks in the and around the house foundations and the wood siding where the insects may be nesting. It's small and dusty enough to really get into the tight spaces and it cleans up easily if you get any on the wood.

We started doing our own pest control, used this for the block walls, targeting the spiders and scorpions. We've seen no scorpions and the spiders including black widows died immediately. Use a mask the dust is fine, and use the bulb sprayer it's handy and user friendly.

Ask a Question
QDoes Delta Dust kill carpenter bees immediately?
Does Delta Dust kill carpenter bees immediately? I drenched two of them today and they both flew off. One was boring a nest and the other was actually in a nest. I believe one actually survived and came back to its nest. Thanks.
ADelta Dust will not kill on contact. In fact, no product will kill a bee or other insect immediately other than Wasp Freeze or a pyrethrin aerosol. The bees that you covered with Delta Dust will die, but not until the bees ingest the dust. When bees walk through a hole or land on a surface that you dusted, they pick up the dust on their bodies. Later, when they groom themselves as most insects do, they will ingest the small dust particles and die soon after. All dust products work better the less you apply. You should only apply a very thin light dusting of the material. Bees and other insects have thousands of microscopic hairs on their bodies and will pick up the dust quite easily. A pile of dust in one place will look like a mountain to a small insect and they will walk around it instead of through it.
QIs Delta Dust safe for having pets in the house such as parrots?
AYes, Delta Dust is very safe to use indoors around pets and children. You should keep children and pets out of the room while you are applying the product, and then it is ok to allow them to come back in once you are done. Of course, you want to use common sense and not dust out in the open or inside the parrots cage, but if you apply Delta Dust into the areas specified on the product label, (cracks and crevices, under appliances, and inside wall voids) there should be no issues.
QWhat is the difference between Delta dust and Drione dust? I want to kill brown recluse spiders.
Which one do you think would be better?
AThe main difference in these two products are the active ingredients. Delta dust contains the synthetic pyrethoid deltamethrin while Drione dust contains the natural ingredient pyrethrins. Both will do a fantastic job eliminating almost any insect including spiders, though you should note that dust insecticides can take several days to actually kill the insect. Delta dust does have one advantage over Drione dust, Delta dust is the only waterproof dust on the market and it will still be effective even if it gets wet.
QHow quickly does the Delta dust kill spiders?
I have brown recluses I have dusted under furniture and behind appliances.
AHow quickly the Delta dust will kill a spider is dependant on how much dust the spider picks up on its body and the size of the spider. Typically dust can kill a spider in as little as an hour or as long as 24 hours or more depending on these factors.
QI had Delta Dust puffed into my attic, how safe is it, and can I go into the attic?
ADelta Dust is a very safe product and only strong enough to kill small insects. If the Delta Dust has already been applied and settled, it should be perfectly safe to re-enter the attic space.

QCan Delta Dust be used in kitchen cabinets safely?
I have fire ants in my kitchen cabinets, bathrooms, even in my clothes closet on my hanging clothes. The best treatment for ants outside is Termidor, hands down. It is sort of a liquid bait when used for ants, and any ants that walk over where you spray pick up the Termidor on their bodies and bring the product back to the colony where they spread it around to all other termites, including the queen, and typically within a few days to a week all of the ants will be dead. Termidor is used around your home like any other pest control product and is applied using a one gallon hand pump sprayer. You should re-apply every 3 months for optimum ant control.
A We do not recommend treating inside the kitchen cabinets with Delta Dust or any insecticide dust as it could contiminate your utensils or food. Chances are that the ants are coming from outside and getting inside the kitchen and other areas. 99% of the time ants are nesting outside and coming inside for food or water.

QWhere could you buy Delta Dust? Home Depot, Lowes, Co-Op, Tractor Supply
AWe carry professional strength products that are not available for purchase in a local home improvement store. We carry the product and offer fast, free shipping! We are not aware of any other local store that will carry Delta Dust.

QWhat is the shelf life of Delta Dust?
I have dusted a hornets nest about 3 days ago. It was high up, and uncovered under the eve, and I completely covered the honeycombs in dust. It was delta dust I purchased a year ago, and the wasps are still alive. There is NO WAY they can get n the nest without picking up the dust, yet they are alive.
AThe shelf life of Delta Dust is 3 years form purchase date. The delta dust should still be effective, as long as it was properly stored in a dry moderate temperature area.

QWhat is the difference between delta dust and tempo dust?
I know they have different active chemicals. Deltamethrin vs Cyfluthrin ? Both claim best for bee control ?
AThe main difference is that Delta Dust is water proof and will keep killing even if it gets wet (other dusts become ineffective if they get wet). Tempo Dust on the other hand is known to have a much faster kill than most other dusts on the market.

QIs Delta Dust Insecticide
a good product to get rid of ants?
I recently bought this product because I was trying to get rid of ants. I have noticed the ants avoid it and it hasn't been effective. I just wondered if this is effective for ants.
ADelta Dust will eliminate ants that cross over treated areas. That being said, ants can be very sensitive to synthetic pyrethroids like the active ingredient that is contained in Delta dust, and can avoid treated areas in some situations. It is helpful to use Delta dust to treat the ant nest directly to eliminate the colony or if that is not possible than to use the dust to treat all of the cracks or crevices where the ants are gaining access to the home. We also carry several products that are non-repellent to ants such as Alpine Dust, Phantom Aerosol and for outdoor use Termidor SC as well as several ant bait products which the ants pick up and carry back to the colony.

QIs Delta Dust good for scorpions? I've found they are very difficult to get rid of.
I live in Las Vegas and just moved into a neighborhood that has a real problem with scorpions. I've never had to deal with them before and finding it very difficult. Please help!!
ADelta Dust is good to use as part of a scorpion control program. Delta dust can be applied using a hand duster directly behind baseboards, to window and door frames, corners, pipes, storage locations, attics, crawl spaces, and other areas which these pests may enter or crawl. We also recommend that you use a concentrated liquid insecticide such as Demon WP around the outside perimeter of your home to help create a barrier to keep these pests out. You should treat a band of soil 6 - 10 ft wide around and adjacent to the building. Also treat the building foundation to a height of 2 - 3 ft where pests are active and may find entrance. It is important that you do not rely on insecticides alone to control scorpions, you should also make some changes outdoors to make your property less favorable to this pest.
Non-insecticide methods for scorpion control are: Harborage Removal- Harborage removal is key to scorpion control and will greatly reduce the numbers of scorpions in the area surrounding the structure, making it far less likely that they will enter. Harborage removal includes eliminating piles of lumber, bricks, and other stacked items that create clusters of tight spaces, elimination of vegetation and other heavy ground coverings near homes and buildings, trimming back tree and shrub limbs from walls and roof, and keeping gutters clear of leaves and other debris.

QCan I use Delta dust in my yard for ground hornets ?
Will it harm our dog if used on the yard ?
AYou can use Delta dust for ground dwelling hornets though you should note that Delta dust does not offer an instant knockdown. We recommend applying Delta dust with a hand duster directly to the hole and to the area immediately around the hole. Applications should be made very early in the morning or very late in the evening when the insects are less active. As long as you follow the product label you can use Delta dust safely in a yard with a dog. If you feel that you would also like an immediate knockdown spray you should consider a spray such as Eco PCO Jet-X. Eco PCO Jet-X provides instant knockdown and kill of stinging insects (does not offer residual control). The Jet Spray can be sprayed up to 15 ft.
QWill Delta Dust work on roaches?
A Yes, Delta Dust is labeled for roaches and works great. However, you typically will see better results by using additional products along side the Delta Dust. You should apply dust underneath appliances and inside wall voids in the kitchen, but you should not apply dust openly into cabinets and drawers. Our most popular product for the cabinets and drawers that is safe to use around food handling areas is Advion Roach Gel. Below is a link to a great article on the best treatment for roaches.

QCan I use Delta Dust under my oven without emptying everything (including the food) out of my kitchen?
AYes, Delta Dust is perfect for underneath and behind appliances as well as in wall voids and cracks and crevices. All of these areas can be treated without removing any food from your kitchen. Of course, you would not want to dust in the open if you have food sitting out on the countertops exposed.
QCan Delta Dust be used inside a utility room that has a bees nest in it?
The room can be sealed off from the rest of the house. Do I need to wear a face mask when applying and cleaning up the area? How long do I need to leave the dust on before going in to clean up the room and the nest? Thank you for your help.
ADelta Dust is an excellent product choice for treating a bees nest. If the bees are in a utility room, there must be a vent or opening where the bees are going in and out. The key to treating the bees nest is to apply the dust where they fly in and out. You would want to apply early in the morning or late at night when the bees are not as active. Go up to the opening and just apply two quick puffs and walk away. Wait a couple days for the bees to pick up the dust when they go through the opening and spread it around to the other bees in the nest. You should open the utility closet once you no longer see activity going in and out of the opening the bees were using. You may have to dust twice to completely knock the whole colony out. Repeat the same steps again if need be. You should wear a basic dust mask when cleaning only as a precaution.
