Product Overview

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 separately) 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 for Bed Bug Control:  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 or an insecticide such as Temprid FX in addition to Delta Dust. Our Bed Bug Control Kits contain everything you need to treat for bed bugs.

Details

DeltaDust 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 Delta Dust, 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.

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.

    Worked GREAT!

    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!!!!

    Amazing!

    By Rhonda on 06/23/2006

    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 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!

    Great results!

    By Carrie on 01/13/2007

    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.

Q
Will the Delta Dust Insecticide decrease a gecko infestation?
A

Delta Dust Insecticide can be applied to listed areas for controlling many pests which geckos eat. If treating theses pests with insecticides such as Delta Dust, it should reduce the gecko/lizard population. They are driven to seek food elsewhere. There are no toxic products labeled for geckos, lizards or any reptiles or amphibians, and given the highly beneficial nature of these creatures there is not likely to be any product for them any time soon. The reason they are on your property are because they can find food and proper habitat. Take away their food and they will forage somewhere else. Take away the conditions they need for hiding and they will seek refuge someplace else.

You really have two options here:

1.Exclusion. Total exclusion can be hard to achieve particularly around the roof-line where there are going to be gaps that would be very hard to close off, but there also could be some obvious flaws such as broken vent screens, holes around cables, pipes or wires, or gaps under doors. All of these can easily be closed with brush strips, caulking, copper mesh (Stuf-Fit), or some other suitable material. Exclusion is the best choice, because it is permanent, and eliminates or reduces the problem in the future too.

2.Outdoor habitat modification. In short, get rid of the reasons geckos are there in the first place. They are there because they are finding the food they need to survive (insects) and a place to harbor. If you can eliminate either of these essentials, you can get rid of the geckos. Spray a good residual insecticide such as Cyzmic CS around the outside of your home to help cut down on the number of insects the geckos are eating. If geckos cannot find enough food they will either move on or starve. Eliminate as much clutter and debris around the outside of your home as possible to eliminate the places geckos like to hide. Rake back mulch or rocks at least 6 inches from the structure. If you need to get rid of the geckos that are already indoors the only options are catching them by hand or using glue boards placed in areas where the geckos travel.

Q
How would I apply Delta Dust in a Crawl Space to kill Camel Crickets?

I recently bought a home that has a sizable population of Camel Crickets in the Crawl Space. There was a leak that has not repaired by the previous owner for some time which saturated some of the subfloor and joists, providing the damp environment that they like, but they're not just in that area, they're all over the crawl space. We're going to repair the structural damage and replace the subfloor, but don't want hundreds of crickets coming up into the house when we rip the old subfloor out. We have been finding them in the house more frequently and want to get rid of them. How should I apply the Delta Dust to be most effective? The Crickets are generally on vertical surfaces such as the foundation walls or the floor joists. I assume they're probably in the insulation as well. The house is about 2000 sq. ft. and I'd like to treat the entire crawl space.

A
You will need to apply about 0.5 lbs -1.0 lbs of Delta dust for each 1,000 sq ft of the crawl space. Spreading the dust over the entire crawlspace using a hand duster can be a labor intensive job. Most folks choose to use a Dustin Mizer Duster to help cover the area and save their hands from pumping a hand duster 100's of times.

Q
Which is the most powerful bed bug repellent

I know about the options for non-repellent treatment (like Temprid SC, Phantom, etc) but I really need a repellent solution: I'm only getting bed bugs from one source - through the wall of a neighboring house (the person who lives there is very old and doesn't want to combat the bed bugs!). So I want to spray a repellent along that side of my house.

A
We do not carry any products that will repel bed bugs. If you share an adjoining wall with someone who has bed bugs, we would recommend using a dust, such as Delta Dust, in the wall void if you can put anything under the baseboards. This is a long term treatment for bed bugs, as well as various other pests as well. You will do a thin layer on the floor so that the bed bugs walk through it and dry out. This is not instant and should be done every seven months. This could be a possible solution so that they do not keep coming into your unit.

Q
Can I use Delta dust in my yard for ground hornets ?

Will it harm our dog if used on the yard ?

A
You 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.

Q
Can Delta/Tempo Dust be applied in a chimney flute to temporarily kill/deter Wasps/Yellow Jackets?
A

There really are not any products that are labeled for use in a chimney or fireplace. We recommend burning a fire in your fireplace for about 30 minutes as the heat will drive any hibernating insects out. You will want to check the screen to see if there is any finer mesh you can use that will still be safe for air/smoke flow at the top of the chimney.

You can spray an insecticide like Cyzmic CS or Delta Dust Insecticide / Tempo Dust into crevices around the outside of the fireplace and chimney of the home to help reduce the numbers flying around and gaining access. Treating the exterior foundation of the home, around windows, doors, under the eaves along rooflines, overhangs but also to bushes, trees, shrubs, etc where wasps may land or hide will also help. 

 In the winter when its cold, wasps and hornets cannot move much at all so this would be the ideal time to have the nest manually removed since they would be unable to fly or move quickly.  Spraying monthly to quarterly throughout the main wasp and warm weather seasons will help achieve this.

Q
Can Delta Dust Insecticide be used in oak trees for carpenter ants?
A

If you already have the Delta Dust Insecticide, you could certainly use that to dust the area the carpenter ants are coming in and out of along the tree. Any that walk through it will pick it up on their bodies and transfer it through the colony. However, if you have not yet purchased the Delta Dust, drenching the root zone, trunk and activity points of the tree with a product like Dominion 2L would likely provide a more thorough elimination of the carpenter ant colony in its entirety. You can also apply Maxforce Complete Granules around the trees and structure as well once the drenched areas are completely dry (when it is not raining also). Please take a few moments to review our treatment article/videos on How to Get Rid of Carpenter Ants for a successful eradication.

Q
Will Delta Dust treat for carpet beetles and bed bugs?

I have bedbugs nymphs in one of the bedrooms and various carpet beetles. I have read that Delta Dust will last up to 6 months but is it safe to walk on the carpets after application? Will this transfer to my bed after walking on the carpets or do I need to vacuum after applying?

A

Delta Dust is labeled to treat both bedbugs and carpet beetles.  However, it would not be applied in areas where walking on it would be an issue. It is labeled for application in cracks and crevices only.  For bed bug control, Delta Dust will not eradicate an infestation and is meant to be used along with other products.  It would be a good idea to take a look at our Bed Bug Control Guide for more information on how to do a complete treatment for bed bugs. 

Many products that will treat bed bugs will also treat for carpet beetles, but with different application instructions.  Please see the below for tips on treating for carpet beetles, and always follow the product label instructions.

How to Get Rid of Carpet Beetles

Carpet beetle infestations can be very difficult to control. The best weapon for getting rid of them is to combine cleaning and insecticides.

• Vacuuming: Carpet beetle larvae like to feed in dark, undisturbed locations like closets, attics, basements, and storage areas. The wide availability of food sources for the larvae (including dust and lint, and pet hair) makes vacuuming the best way to ensure there is minimal food for the larvae to feed on. Vacuuming can also help to remove the larvae and adult beetles already in the home. Regular vacuuming and laundering of rugs, furniture, and linens can help to ensure the beetles are removed and have no food source. If you find a contaminated item, bag and remove this item from your home, if possible.

• Proper storage: Before storing silks, woolens, or furs, dry clean as the beetles are attracted to stains and soiled garments. Store in a well-sealed container, using mothballs. Mothballs can limit the beetle’s attraction to the wool or silk. Store pet food, dried meat, and other dried animal products in a well-sealed container.

• Insecticides: For things that cannot be washed or dry cleaned, insecticides are the best bet for prevention and eradication. Temprid SC is an excellent products to use.

Insecticides can be used for spot-treatments, as a boundary at the edges of rugs, under rugs, under furniture, walls and floors of closets, shelving, cracks, and lint or dust accumulating areas. Be careful around oriental rugs or other fabrics, as some insecticides can stain. Never spray clothing or bedding with insecticide, and always read instructions.

• Outdoor maintenance: Adult carpet beetles are most commonly found outside. They feed on pollen and nectar, but lay eggs in bird, rodent, bee, or wasp nests or old spider webs to give the larvae an abundant food source. Clearing these away from your home, along with checking near highly pollinating plants near your house and checking cut flowers for the beetles before bringing them inside.

Q
How do I treat wall voids for bed bugs with Delta Dust?

Been battling bed bugs for quite sometime. I have used Temprid SC at .16 per gallon of water with Gentrol at 3oz per gallon, then rotated to Phantom TI/IT at it's strongest levels as well with Gentrol again.. Took the beds apart, they are in encasements. I have searched every inch of the room and believe they are coming out of the wall. Obviously I need to treat every wall void and only removing 2 outlets on the wall will only treat 2 wall voids out of a possible 16 wall voids... So is it okay to just drill a hole then dust and then cover it with spackling?

A

We generally would not recommend creating new ways for bed bugs or other insects to access voids or hide by drilling holes into the walls. A remote wall void would be the last place for bed bugs to go, and they are usually only present there in cases of severe infestations that have been present and untreated for years; you would be able to see bed bugs easily in other areas of the structure. We suggest using Delta Dust or another dust such as CimeXa Dust where you fairly easily treat using a hand duster such as the Long Shot Puffer Duster. (CimeXa Dust is very successful as part of bed bug treatments and cannot break down over time.) Keep in mind that bed bugs, like other insects, wants to stay close to their food source. I recommend taking a few moments to review our Bed Bug Inspection Guide and performing a thorough inspection of the area if you believe there are still bed bugs but are having trouble locating harborage areas. You can also use monitoring tools such as ClimbUp Insect Interceptors or Trappit BB Detectors to help monitor areas where you suspect there may be insect activity.

Q
Is Delta Dust Insecticide effective for killing roaches? I have an incredible problem.
A
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.

Q
Can 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.  

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.

For inside, labeled to apply indoors only in cracks and crevices and/or inaccessible areas, only to treat active infestations inside though.  These would include the void underneath your cabinets, underneath and behind appliances, inside wall voids, water heater closets, etc.  You would not want to place this bait inside a cabinet with plates and silverware or on any food handling surface.
