"Every spring, our garden is overrun by aphids. This year, I applied Dust to Dust around my planter boxes as well as on the stems of my plants to try to fend off the aphids before they arrived. Well, I haven't seen one yet and my plants look healthier than ever! I heard this powder is great for ants, too, so I've applied it around my foundation. So far, so good!"—Jason M., Verified Customer

Ensure that bugs have nowhere to hide

Insects can be relentless in their pursuit of infiltrating your home. They'll wiggle their way through even the tiniest of cracks and crevices and act like they own the place. But fear not, because Dr. Killigan has got you covered.

Dr. Killigan’s Dust to Dust Plant-Powered Insect Powder is a lab-proven bug-busting formula made with super-fine silica and essential-oil nanotechnology. This proprietary solution is guaranteed to kill ants, roaches, fleas, ticks, silverfish, earwigs and more—all within 24 hours of contact.

Stop insects in their tracks with Dr. Killigan’s cutting-edge formula

Dust to Dust employs silica to break down the delicate wax layer that covers insects' exoskeletons. This wax coating is critical for these bugs as it helps prevent the loss of water from their bodies through the exoskeleton. The breakdown of this layer caused by silica ultimately leads to the insects' death through dehydration.

Silica is most effective in arid, low humidity conditions and is particularly effective against crawling insects. The formula can also be applied to treat flying insect nests. The volatile essential oils used in the Dust to Dust® formula are encapsulated within the silica particles themselves during the formulation process. This encapsulation method allows for a more precise and controlled release of the volatile organic compounds. These volatile organic compounds have a distinct mode of action from the silica in that they disrupt the insects' central nervous systems, leading to chemical imbalances that ultimately result in their demise.

Even after the volatile organic compounds have evaporated, the silica in the Dust to Dust® formula continues providing residual protection against insects. The formula acts as a carrier and barrier for the volatile essential oils, protecting them from premature degradation and ensuring their efficacy over a more extended period. The inclusion of nano-sized particles of essential oil further enhances the Dust to Dust formula's effectiveness by improving its cellular penetration.

Defend your home—and Peace and Sanity—with Dust to Dust

Dust to Dust is highly effective against insects in cracks, crevices and elsewhere both indoors and outdoors. In addition to these areas, Dust to Dust can be applied directly onto both pets and plants for a proactive solution to harmful insects, such as aphids, ticks and fleas.

As a preventative measure, apply Dust to Dust liberally around the perimeter of your home to avoid any infestations. However, if you are currently battling an insect invasion, fortify your defenses by applying Dust to Dust at and around the source of the problem. This includes nests of ants, roaches and other bugs. This powerful formula is designed to put a terminal end to a wide range of pests on contact, gradually ensuring complete freedom from insects.

As a pioneer in insect control, Dr. Killigan’s Dust to Dust is backed by hundreds of side-by-side tests, proving this formula is a safe (when used as directed) and effective insect powder. While Dust to Dust’s kill times are up to 50% faster than products from other brands, Dr. Killigan’s formula is exempt from the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), meaning that our solution poses little to no risk to both humankind and the environment.

Frequently Asked Questions

Our Dust to Dust powder is non-toxic due to it being FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) exempt. It contains silica, a mineral from the earth’s crust, which is generally regarded as safe and is also a FIFRA 25b exempt inert ingredient.

The best way to use Dust to Dust proactively is to apply the product outdoors around the foundation, near entry points, and all other areas where insects can access your home.
Garage doors can also tend to allow space for insects to crawl through. Apply this product along the bottom of the walls in your garage and near the garage door tracks.

Attics, as well, are a common space for insects and spiders to hide out because they typically don’t see as much foot traffic and are often undisturbed.

We recommend that you monitor the areas where the product has been applied and reapply as necessary. Heavy rainfalls outside or heavy foot traffic indoors can be cause for reapplication. This product tends to stand out so it is relatively easy to see where it is and isn’t. Reapplication is key to keeping pesky invaders fully out of your home.

“Set It and Forget It”

Our Dust to Dust powder is not intended for consumption.

The powder may cause nausea and vomiting if consumed in excessive amounts. If ingested, please consult a doctor or veterinarian.

Dr. Killigan also offers our Insect Buster, a bulb duster for non-toxic insect powders. Combined with Dust to Dust, the Insect Buster targets and kills: bedbugs, fleas, ticks, spiders, cockroaches, earwigs, silverfish, scorpions, ants, beetles, mites, moths, hornets, and more.

Yes, 2 oz of this product can be mixed with water to create a wettable dust but it needs to be shaken frequently.

A standard-sized trigger sprayer (similar to our Six Feet Under trigger sprayer) works well in the application process. Mini trigger sprayers and pump sprayers (which provide a fine mist) do not work well. Higher output sprayers are best. We recommend using the stream setting, which gets the silica and other ingredients to come out easier than when misted.

We encourage sensitive groups, such as individuals who may have allergies, to wear a face mask when spreading Dust to Dust to prevent breathing in the fine particles. We recommend you hold the applicator below the waist or low to the ground if you are not wearing a face mask.
