    Why Use a Wasp Killer Powder?

    With so many wasp killer spray recipes floating around the internet, it’s natural to wonder what the best product for killing wasps truly is.

    It can be kind of jarring if you’ve never heard of insecticide dust, but hear us out. This method of pest control is less popular in comparison to sprays and traps, but the goal is the same: to rid your property of pests in the most effective way possible.

    A Little Goes a Long Way

    Normally, dusts are administered in cracks and crevices which are otherwise very difficult to reach.

    Not only is the pulverized form of a dust ideal for this type of application, but a small bit of the insecticide can disperse freely through the air and cover a wide volume of space.

    One can argue that in this way, using an insecticide dust is a much more economical method of pest control than an indoor wasp spray, or even a high-powered commercial wasp spray.

    Set It and Forget It

    The best-case scenario for insecticide dust plays out like this:

    • an insect walks through the dust and begins to track it back to its home colony, inhaling it every step of the way.
    • the insects in the colony become exposed to the dust as well, picking up the poison of the active ingredient
    • the insects die off, or remain exposed to the insecticide (where death is imminent)

    In this scenario, the only responsibility on the part of the user is the initial application. Otherwise, nature runs its course, and the pests die out with no problem.

    Take a look at the video below to see firsthand how a wasp reacts to exposure to an insecticide dust.

    Long Lasting Effects

    The main benefit of using a pesticide dust over a spray or a trap is that it can generally over a layer of residual protection against new pests from returning.

    This barrier can last anywhere from a few months to a few years, depending on the materials of the dust.

    The effectiveness of the residual protection also depends on whether the barrier can be left undisturbed. Attics and untouched spaces are ideal, whereas outdoor areas with lots of traffic and/or rainfall may have decreased effectiveness.

    Where is the Best Place to Apply Wasp Killing Powder?

    If you administer this wasp killing powder along the crevices of your deck, will it manage to kill off the ant colony below as well?

    Keep reading below to find out whether you can take out any pesky species along with your wasps!

    In the Attic or Basement

    This is probably the best place in your entire home to apply wasp powder.


    Well, it’s a quiet, undisturbed place where the chemicals can work their magic. Just as we mentioned earlier, many of these insecticides are effective when left alone by humans–the longer, the better.

    Female wasps tend to hibernate in attics and basements during frigid winter months, so applying this powder in early autumn is optimal in order to keep your home wasp-free during the winter.

    Eaves, Jambs, and Voids

    These are also ideal spots to administer wasp powder; not only because it will sit untouched by the residents of the home, but because this is another piece of prime real estate for female wasps to hibernate in the winter.

    Be sure to use extreme caution, however, when treating a closed-off area of your home. Nests hidden in these areas can be tricky to remove, and the wasps residing inside can fly out at you at full force. Be sure to wear protective clothing and have your wasp dust at the ready.

    How About the Garden?

    This is where dusts tend to fall short.

    Why is that?

    Well, for all their benefit in being able to touch those difficult-to-reach spaces in all the nooks and crannies, wasp powders tend to clump up when mixed with water.

    The dust composition means that rainwater and groundwater washes this type of insecticide away rather easily, so if you’re applying it in an outdoor environment, you’ll need to do so frequently.

    If you live in a more desert city like Phoenix, AZ, or Albuquerque, NM, with less precipitation, then you might have some more success with outdoor applications.

    Can Wasp Powder Kill Other Pests?


    Most wasp powders feature active ingredients which target a wide range of pests. This means that by using these wasp powders, you’re able to take a “one-stop-shop” approach to pest control, which works out to be a much more economical deal for you in the long run.

    If you’ve got an ant problem in your kitchen, a wasp problem by the pool, and a roach problem by the garbage bins, you’re able to streamline your pest control needs into one product.

    There are certain wasp powders, however, which are targeted toward wasps, bees, and other stinging pests; one of which we have reviewed in our list.

    Wasp Powders, Dissected

    In the below section we break down each of our product recommendations in a little more detail.

    Related Articles

    Bayer Delta Dust Insecticide Powder

    This is our top-rated product on the list because it eliminates problem wasps quickly, and without the threat of interference.

    This dust is affordable and lasts for a while, as the contents of one unit package is a 1lb bottle. One use is a simple puff, which only takes a few ounces of the dust. A little goes a long way with this stuff, which means that the price you pay lasts you for years to come.

    Delta Dust is totally waterproof, which is our favorite thing about this particular product as opposed to the rest on our list. Not only that, but it’s approved for use in areas that handle food, as long as the user follows all safety guidelines.

    Delta Dust is most commonly used outdoors and in hard-to-reach areas like crevices, eaves, and door jambs. In other words, it’s used in places where wasps love to build nests, so it’s ideal for puffing in their general direction.

    You will need an external duster to spray the dust, which is sold separately. If you don’t own one already, this will be an added expense. However, it should be seen as an investment–especially in light of the fact that wasps and other pests are annoying at best, and dangerous at worst.

    We recommend this product for those who want a reliable way to kill off the wasps in the yard or in the attic without a lot of extra hassle.

    The Good And The Bad

    • Gets the job done fast and well
    • Affordable product that lasts a long time
    • Active ingredient derives from natural sources
    • 100% waterproof and can hold up to the elements
    • Approved for use in food-handling areas
    • Requires a bell duster to administer
    • Some customers complained that dust did not work against bees and yellow jackets

    Tempo Dust Insecticide Powder

    When you use Tempo Dust, you get the power of the insecticide then and there, but for up to 365 thereafter as well.

    Tempo Dust specifically targets wasps, hornets, yellow jackets, bees, and other flying pests.

    This dust, though it has the same appearance as Delta Dust is a little bit different. With the active ingredient cyfluthrin at 1%, this dust works to kill the wasps on contact, then protect the area where it’s administered for up to a year afterward. It’s non-staining and leaves no odor, so it won’t cause a disruption.

    Tempo Dust, like Delta Dust, requires an external applicator for use.

    This dust is normally used in commercial settings, as it’s not recommended for use in food-handling environments.

    The Good And The Bad

    • Targets wasps and hornets
    • Leaves no odor and can prevent new wasps for up to 1 year
    • Works to kill wasps immediately
    • Not recommended for home or food-environment use
    • Requires an external applicator

    CSI D-Fense Dust Insecticide

    This is an all-around great product because it can be administered in so many different spaces.

    CSI D-Fense Dust is listed as both an indoor and outdoor insecticide and can be used in both food-handling and non-food-handling atmospheres, provided all safety guidelines are observed.

    The dust itself is pre-mixed and ready to use, requiring only an external hand duster for administration into the air.

    If left untouched, this dust provides a defense of up to 8 months of residual protection against new wasps and other pests from the time of original dusting.

    We recommend this product for adults who live alone, or adults who don’t have kids or pets. If accidentally ingested, this dust can be highly toxic.

    The Good And The Bad

    • Ready to use upon arrival
    • Kills wasps instantly by shutting down their central nervous system
    • Provides up to 8 months of residual protection
    • Can be used in a variety of spaces
    • Requires a hand duster for use
    • Can be toxic if licked or ingested
    • Some customers complained that it was ineffective against yellow jackets

    CimeXa Insecticide Dust

    This product is slightly different from the others on the list, but we’ve included it here because it achieves the same goal: to kill wasps.

    CimeXa Insecticide Dust is made from an amorphous silica gel which works continuously over time to kill targeted insects. Because of the silica composition, this product doesn’t degrade over time and stands up to all elements, making it an ideal product for outdoor use.

    As with the other dusts in the list so far, a hand duster is required in order to use this type of insecticide dust.

    We recommend this product for those who have wasps in hard-to-reach places that don’t get a lot of access. CimeXa Insecticide Dust works its magic when left alone, so by being in a sticky spot, that’ll really do the trick.

    The Good And The Bad

    • Kills wasps upfront
    • Provides up to 10 years of protection
    • Silica coating keeps the insecticide intact and weatherproof
    • It's a bit pricier than other options
    • The user must use a hand duster, dols separately
    • Some users have safety concerns around children

    Drione Insecticide Dust

    Drione is the professional’s choice for wasp eradication. But it also works on other pests as well. Here are just a few examples:

    • Bed bugs
    • Drywood termites
    • Fleas
    • Scorpions
    • Ticks

    Use Drione mostly indoors for crack and crevice applications. The 1.0% pyrethrin formula is strong enough even for the heaviest infestations. It also has almost an unlimited residual effect in dry areas.

    This Drione kit comes with a professional bellows duster. Simply fill about halfway. Be sure to shake often to prevent powder from settling at the bottom.

    The Good And The Bad

    • Superior knockdown performance when compared to other dust formulations
    • Highly effective for a wide range of pests
    • Excellent residual
    • Comes with a professional-quality bellows duster
    • Professional-grade insecticide dust, use caution, wear PPE while applying
    • Do not use around children, pets, or food areas
