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
I have a yellow jacket nest in a crack in the cement block foundation of my house what can I use to kill them?

Do you have a product for this. I have tried liquid wasp killer and seven dust neither did any good

A
Please check out our article "How to Get Rid of Yellow Jackets". If you can get close we highly recommend applying a dust like Delta Dust that is water proof and when the yellow jacket comes in contact with it, the dust will transfer from bee to bee killing adults and larvae. This product would be great to use in those cracks in the cement blocks.

Q
How to get rid of cicada kiiler wasps flying around the house

I have cicada wasps and the kids will not go outside. I sprayed Bifenthrin, but it did not seem to kill them.??? How can I get rid of them. Last year I sprayed Bifenthrin in all the holes they made in the ground. I also poured ammonia in a few holes hoping to kill larvae. Help now what?

A
Cicada Killer wasps thrive in disturbed environments, such as landscaped yards and places where bare soil is exposed. You can discourage the wasps from nesting in your yard by cutting your grass on the highest setting and by adding a thick layer of mulch to flower beds during the Cicada Killer Wasp season. These wasps do not like over saturated lawns either, so over watering during their season will help prevent them. Unfortunately, there is no fool proof way to prevent cicada killer wasps. For current infestations, you would need to use Delta dust in each individual burrow.


We also like to let our customers know that the Cicada Killer wasps are beneficial insects that provide free pest control for a couple months each year. Cicada killer wasps paralyze and provision their burrows with other insects to feed their young.  The beneficial Cicada killer wasps, while large and intimidating to see, are mostly harmless and there have been very few reports of anyone getting stung by just being near them. In most cases where a sting was reported, the wasps were being held or molested in some way. Cicada Killer Wasp stings are also reported to be almost painless.

Q
Does Delta Dust work on all types of bees?

I've used it in the past with great success. Recently I've noticed alot of bees going in under the siding on my house. I've applied the dust multiple time over the last few weeks and the bees are still entering and leaving. Im not sure what type of bees they are.

A

The Delta Dust will work on any type of bee, but they may be further up in the void than the dust is reaching. Or they may have another exit point you can't see at the moment, or just a large colony in general. You can give it a few more weeks or potentially try a transfer spray like Phantom Aerosol which is a very slow kill but gets carried through the nest through touch a little better, in this case.

Q
Since flood we have palmetto bugs

Since flood two years ago we have had palmettos each year I have counted 10 and 12 respectively. That's 22 too many. And yes they are palmettos I wish they weren't. Please list everything I need to buy to rid myself and prevent future bugs. Also I have two feral cats that live under my house and 8 cats that live inside along with a teaching squirrel. (Pet squirrel used for school visits and off times is a pet. Their lives cannot be endangered.

A
Since you are positive these are palmetto bugs, please visit out Palmetto bug control page. Use Delta Dust in wall voids. Alpine WSG can be used as a perimeter treatment. Treating the outside perimeter and entry points. Indoors cracks and crevices.

Q
My pro pest company uses Delta dust in all the outlet and switches for roaches/pests but I see in your DIY video you use Maxforce bait.

My pro pest company uses Delta dust in all the outlet and switches for roaches/pests but I see in your DIY video you use Maxforce bait. Can you help me understand why to use one vs the other? It seems to me bait would be the better option as the pest would bring it back to the colony (assuming Delta dust doesn't work same "domino" kill way)

A

Delta dust is commonly applied in areas like electrical outlets, light switch plates and other areas where you do not want to apply a liquid insecticide. It will last if left undisturbed for 6-8 months. Bait gel (including Maxforce Roach Bait Gel) can be applied in that area (if there is not any dust present) but should be applied every two weeks to maintain a fresh food source for the roaches. It is only labeled for roaches. Delta dust can eradicate many other listed insects including roaches. If you are mainly treating roaches, we suggest applying a liquid insecticide mixed with an IGR (insect growth regulator) and water and treat on the exterior of the structure and the interior cracks and crevices. Apply the bait gel in areas (where you have not sprayed) like the cabinets, under the sink, behind the toilet, above the door frames, etc. Apply dust in the wall voids, outlets, light switch plates, etc. Bait is applied every two weeks, dust is applied every 6-8 months, liquid soultion is applied every 30 days outside and every 90 days inside.

Q
How far will Delta Dust Insecticide travel before settling once airborne?
A

How far an insecticide dust such as Delta Dust may drift before settling will depend on several factors such as what kind of duster is used to apply it, the humidity in the area, and any air movement in the space where it is applied. If you would like to share more about where you are treating, the target pest, and what kind of duster you are using, then we can better assist you. Keep in mind that Delta Dust is for use only in cracks and crevices and interior voids, not for use in open living spaces or outdoors.

Q
Is 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.

A
Delta 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.

Q
Does 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.

A
Delta 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.
