Does ant dust work? Ant dust is an on contact ant killer that is very effective for controlling ants, especially their trails and entry points.

What is the best ant dust on the market today? How should you use it and is this type of insecticide safe for humans and pets? Let’s find that out!

How Does Ant Dust Work and How Effective Are They?

In a nutshell, ant dust is a powdered insecticide. The majority of these products can deal not only with ants, but also with other pests (such as slugs, spiders, fleas, crickets, and others). Ant dust can be used both outside and inside and the best part about this insecticide is that you can sprinkle it over inaccessible areas. The powder is so small that it can easily get into cracks or crevices.

The active ingredient kills the insect only when it comes in contact with the dust. The insecticide affects the ants’ nervous system and/or exoskeleton. You can sprinkle the dust right over the actual nest to get rid of the colony. The great news is that you wouldn’t have to reapply the product too often as a lot of insecticide dusts are waterproof and won’t get washed away that easily.

If you have only a few ants running around or you know exactly where the nest is located, an ant insecticide dust can be a great solution. However, in case you have a severe infestation, it is not enough to use only the powder. Usually, people prefer to use ant dust together with baits and general sanitation.

The fact that the powder kills the ants on contact is simultaneously the product’s biggest advantage and disadvantage. On the one hand, you will be able to kill the ants that touch the dust very fast but on the other, the queen and the ants that don’t forage might not be affected by the powder. This is where bait comes into the play.

How to Use Ant Dust: Instructions & Tips for Indoor and Outdoor Use

In most of the cases, these ant killer dust products are ready-to-use, you wouldn’t need to mix it with water or prepare the solution in any other way. The product might come with a special duster or in the form of a sprinkler. However, you can always buy a bulbous duster that will help you apply the dust (or use a simple tablespoon or paintbrush).

Even if the product is non-toxic, avoid applying it to exposed surfaces (especially, inside the house). The dust can be applied in cracks and crevices, behind various appliances, around windows and doors, in wall voids and false floors, along baseboards, and so on.

In case you are applying the dust outside, you can create a barrier around the perimeter of your house to keep the pests away. Or you can sprinkle a tablespoon of dust on the top of the nest. Try to apply the product when the temperatures are between 65 and 80 degrees Fahrenheit. By the way, dusts work best when applied lightly and not in large quantities.

How Long Does It Take for Insecticide Ant Dust to Work?

How Long Does It Take for Insecticide Ant Dust to Work

Usually, it will take around 3 to 4 days for the dust to work its magic. If nothing happens, make sure to reapply the dust. Some products might lose their properties in wet areas. Ideally, you should apply the dust when it’s dry, in order for it to work.


Is Insecticide Ant Dust Toxic for Humans?

It depends on the product that you decide to use. Diatomaceous earth, for example, is non-toxic (but you still wouldn’t want to breathe the powder in). However, plenty of other ant dusts have a toxic active ingredient that can be harmful to humans.

Make sure to read the label with care and don’t sprinkle the dust to exposed surfaces or close to ventilation. Thankfully, ant dusts are usually applied to hard-to-reach places, so the chances are high that your family members won’t come in contact with the product.


Is Ant Dust Toxic to Dogs, Cats, and Other Pets?

The dusts that use boric acid or Diatomaceous earth are non-toxic for humans or pets. However, you still don’t want your pets to breathe in the solutions or, for example, eat them. So, just in case, keep your pets away from the non-toxic products.

The rest of the ant dusts have a toxic active ingredient that can be harmful to the animal’s health. Thankfully, ant dust that has been applied to crevices or cracks can’t be reached by your pets. You have to be very careful when using any type of insecticide and ant killer dusts are no exception.
