How Does Ant Powder Work

Reading Time: 5 minutes

How does ant powder work? Well, when applying ant powder, ants usually start dying within 30 minutes of contact with the ant powder. Once applied to the area, the dust particles will provide continuous defence for up to 12 weeks, keeping your home or office free from ant infestations.

In most cases (but not all), ant powder will not affect the queen ants as ants will not return to the nest from where the dust is applied (see more below about queen/flying ants). However, if you have a large number of ants, the ant powder only may not be enough to eradicate the problem entirely.

If you are wondering how ant powder works, it’s a simple process. The dust in the ant killer powder starts to kill ants upon contact. It affects both the ‘exoskeleton’ and the ants nervous system, not very pleasant I know. Because it sticks to the ant’s body, it won’t wash off. Powder insecticides can be sprinkled or ‘puffed’ around the nest or on the soil surrounding it. Powder insecticides are especially effective against carpenter ants.

In the UK, carpenter ants are often seen inside properties where large amounts of wood have been used during the renovation or construction processes for both exterior and interior works.

Brown carpenter ants (Formica ligniperda) nest in and around these woody areas, they also collect ‘honeydew’ from ‘aphids’ that live on plants like geraniums by ‘stroking’ them with their antennae.

Diatomaceous Earth - An Environmetal Non Toxic Option

Diatomaceous earth (DE) is a ‘versatile’ non-toxic method of pest control because it can be used in many ways and has different effects on different insects.

Somehow, the microscopic pieces are razor-sharp and will cut through the exoskeleton of ants making them ‘dehydrate’ until death, which comes quickly by itself.

You can spray this substance on the ground or inside your home. You can also use it to create a barrier around the house that repels ants. This natural pesticide is non-toxic and safe for humans and pets.

Diatomaceous earth is a great way to get rid of ants without using harsh chemicals. It’s an easy and inexpensive solution that you can use in the form of dust, and puff/spray it on surfaces where there are ant trails/formations then sweep it up afterwards!

Users of (DE) are to ensure they follow the instructions carefully and wear a mask and gloves when applying using this method.

Does Ant Powder Work 100% of the Time?

When you have a problem with ants, it’s tempting to use a chemical insecticide. However, many chemical ant repellents are dangerous for your pets and children. And some don’t work at all well.

White chalk dust may deter ants for a while, however, ants are smart and will eventually find a way to get around it. If you can’t afford the expense of buying expensive insecticides, try some natural remedies instead. We have mentioned (DE) above,  you can also try using chalk and or vinegar to repel ants.

If ants are coming from outside, you can also use a perimeter pesticide. Perimeter pesticides are usually ‘kill-on-contact’ and generally are pretty much 100% effective.

Another natural ant repellent is ‘citrus’ fruit juice, which will break ant trails. This method requires less effort to spread around on your part but has a lower impact though. If you use ant bait stations, however, you’re more likely to get far better results from these methods.

Ant bait stations are totally enclosed and very easy to use. Ants enter a bait station, taking back the liquid to their nest. The active ingredient is then spread throughout the whole colony, stopping ants in their tracks and destroying the complete nest at the same time.

How Long Does it Take for Ant Powder to Work?

Insecticide ants do not die instantly after crossing treated areas. In fact, they may still be sighted over the treated area several hours later. It is important to have realistic expectations and know that there is no such thing as an ant-free home 100% of the time.

Insecticide ants do not harm humans, Nevertheless, some ant powders contain a ‘toxic’ active ingredient. However, diatomaceous earth (DE) may cause some slight irritation on the skin, or a slight sore throat or perhaps a little cough if ingested by humans or pets.

We advise gloves and a mask when laying down (DE).  One should always use the Food-grade diatomaceous earth as it is low in ‘crystalline silica’ and considered safe for humans and pets.  

Does Ant Powder Kill the Nest?

One of the main questions a homeowner may have is: “Does Ant Powder Kill the Nest?” Luckily, there are several different ways to get rid of ants and or eliminate the nest without resorting to poisons.

While ‘Borax’ may be a well-known ant killer, we do not wholly support its use. If you decide to buy a commercial borax product designed as an insecticide, use it as directed on the label.

Borax can irritate your eyes, hands or lungs if you breathe fumes or ingest the Borax from any residue on your hands. We prefer to us (DE) as mentioned above.

Luckily as we demonstrated it’s not the only option.  A few different pesticides are available, and not all of them have the same effectiveness. For example, some granular insecticides can kill the nest, but they may not kill the entire colony.

Other common ways to eliminate ants include of course using a sprayed insecticide. These can be applied to ants in their nests, but they require a sturdy spray wand to be effective.

The Spear and Jackson Pressure Sprayer and Spraywand is a long wand 94cm (3ft), which is a handy way to get down for ‘flooding’ the nest only. Powders are especially useful because they can be blown into the nest from different angles. 

Does Ant Powder Kill Flying Ants? Yes, it does in short. When the queens emerge usually in late June and disperse they go to form new colonies. These larger winged individuals emerge en masse. 

During this time it may be preferable to use contact insecticides like Nippon Ant Killer Spray around the nest entrances to kill the queens as they emerge.

How Does Ant Powder Work? Although ant powder can be an effective way to kill ants, it is important to take into account the different factors that influence its effectiveness.

The best time of year to use ant powder, how you should apply it, and which types of ants it works on all depend on the specific situation.

In general, natural methods like using diatomaceous earth (DE) tend to be more effective, while pesticides can sometimes cause more harm to the environment and potentially to your family and pets.
