Delta Dust vs Drione Dust Review

Dusting is a popular method used by pest control professionals. It essentially involves the application of a toxic dust directly on a nest or into areas of potential infestation. The 2 most common insecticide dusts are Drione dust and Delta Dust. So what are the differences?

Drione Dust to Kill Carpenter Ants

Drione dust is a mechanical and chemical insecticide. The mechanical component is diatomaceous earth (DE) or a similar silica based powder. Under a microscope, you will see that the powder is essentially microscopic glass shards which will cut up and dry out insects that crawl over them. In addition to DE, Drione dust contains pyrethrins which are natural chemicals from chrysanthemum flowers. Pyrethrins have a nerotoxin effect on insects, causing paralysis leading to death. However it is widely considered the safest of all insecticides and the Environmental Protection Agency’s October 2011 Pyrethrins/Pyrethroid Cumulative Risk Assessment indicates that exposures from the many current uses of pyrethrins and pyrethroid insecticides do not pose risk concerns for children or adults.

Delta Dust to Kill Carpenter Ants

Delta dust is actually a brand name that has become synonymous with a type of insecticidal dust (like Kleenex is to tissue and Pampers to diapers!). Delta is short for deltamethrin which is a synthetic form of pyrethrin. Delta dust is also generally cheaper than drione dust!

Delta (Synthetic Deltamethrin) vs Natural Pyrethrin

There are several differences between synthetic deltamethrin over natural pyrethrin. Pyrethrin in Drione dust is biodegradable and will disintegrate quickly when exposed to sunlight, air and water. Synthetic Delta lasts longer and is effective for 6-8 months.

So which should you use? It depends.

If killing the carpenter ants or other insects is your top priority and you do not have to consider the safety of pets, a pregnant wife or infant then go for Delta dust.Or you can also consider Bayer Drion Dust which contain 1% Pyrethrin, 10% Piperonyl Butoxide (PBO) and 40% Amorphous Silica Gel (DE). PBO is is added to increase the effectiveness of pyrethrins against insects, however it has been linked to a delaying development in young children up to 36 months old; an effect similar to lead. I would personally advise against using a PBO based product if you have a pregnant person or young child.

If you are concerned about safety, then use a dust that contains pyrethrin as the only active chemical ingredient such as Evergreen 1% Pyrethrin Dust Insecticide.

Diatomaceous Earth to Kill Carpenter Ants and Other Bugs

If you are really concerned about child and pet safety, then use diatomaceous earth by itself which is a purely mechanical insecticide with zero chemicals.

Don’t Forget a DUSTER!

Finally, whether you get Delta, Drione, Pyrethrin or Diatomaceous Earth, don’t forget to get a duster together with it. The B&G Bulb Dust-R Model M1150 Hand Duster can be used to apply Delta, Drione, Pyrethrin or Diatomaceous Earth.

Carpenter Ant Control Kit Review

Amazon ImageThe Carpenter Ant Control Kit reviewed consists of 2 products so as to be doubly effective to get rid of carpenter ants.

The products are:

1. Advance 375a Select Granular Ant Bait – 8 oz.

2. Maxforce Carpenter Ant Bait Gel-1 Tube

Have you used ant baits on carpenter ants in the past and found that  ants were not interested? It might be that you were using the right bait but at the wrong time. Carpenter ants have alternating appetites. They alternate between eating protein and sugar, but not both at the same time. This is the reason why some people are unsuccessful with the baits they use for carpenter ants. It is also why some carpenter ant bait seems to be ineffective and receive negative reviews. These periods of eating either protein or sugar can last up to several weeks. So if you put out a sugary bait when they are in the mood for protein, it will be virtually useless.

This kit combination is not simply a marketing gimmick to sell you more products. Whether your ants are in the mood for protein or sugar, this kit has you covered with both the protein based Advance Granular Ant Bait and the sugar based Maxforce Carpenter Ant Bait Gel. You might start to see some effects in 3-5 days, with initially more ants swarming to the bait and then a reduction in their number as the poison starts to take effect. Don’t fret if you still see ants running around after a week. Be patient, it will usually take 2 to 4 weeks for all the ants to be killed.

Both employ slow-acting ant poisons which are designed to be carried back to the ant nest in order to kill the whole colony. If you have a problem with carpenter ants and have not had success with your bait, it’s time to switch!

Finally, you can simply buy this kit and have it shipped quickly as one item or buy the 2 items separately, which could save a few bucks. Personally if I had a problem with carpenter ants, I would just get whatever shipped with Amazon Prime in order to deal with them asap.

How to Get Rid of Carpenter Ants Naturally

If you prefer not to use toxic pesticides and other chemicals, this post will help you learn how to get rid of carpenter ants naturally.

There could be various reasons and situations where you might prefer to use non-toxic methods to kill carpenter ants. For example I have two dogs at home and prefer not to have toxic ant bait lying around the house in case the dogs eat it! Neither do I like spraying pesticide for the same reason that it risks exposing my pets to the toxic chemicals. My wife also does not like the smell of insecticide sprays and strongly objects to their use. Or you might have a toddler who might inadvertently come into contact with these toxins  and develop a reaction from touching or worse ingesting it.

In such cases, a good non-chemical, non-insecticidal, non-toxic bug killer is diatomaceous earth. Dia-what?? Diatomaceous earth or DE is a white talcum powder like substance that is actually the fossilized remains of marine plants known as diatoms.

Is Diatomaceous Earth Safe?

Amazon ImageDiatomaceous earth is non-toxic and harmless to humans and mammals like dogs, cats, cattle, etc. In fact it is used in things like toothpaste and cat litter. DE is also used as a health supplement for both humans and animals. It is eaten by people to detox their digestive tract and also fed to animals as a de-wormer. For people who take DE as a supplement, the dosage is from a spoonful to a quarter cup a day.  So yes, DE is very safe. The only thing I personally dislike about DE is that the powder makes the area it is applied to feel dusty.

How Does Diatomaceous Earth Work?

DE is also mixed into grains that are kept in storage to kill grain eating bugs and this is where it is relevant as a tool to get rid of carpenter ants. In fact DE can be used to kill any insects with an exoskeleton (a hard outer layer that protects the soft body inside) such as ants, cockroaches, ticks, fleas and bed bugs. DE works in two steps.

First the fine powder is actually microscopically hard and abrasive. It is essentially silica which is what glass is made from. So when an insect comes into contact with it, the powder get stuck on them and in their joints, cutting through the insect’s exoskeletons. It is also inhaled and generally gets into the insect’s orifices.

This brings us to effect two. Since DE is mostly silica, it is a very effective desiccant. This means it will absorb moisture and dry up its surroundings like silica that is commonly used for dehumidifying. The sum effect of using DE on an insect is that it coats the insect, cuts it open, cuts it up internally and dries out the poor creature. Also since DE’s effectiveness is completely physical and mechanical, insects do not develop an immunity to it unlike chemicals.

How to Get Rid of Carpenter Ants Naturally Using Diatomaceous Earth

Applying DE only to areas where the worker ants gather food will kill them but will not get rid of the queen and colony. The powder must be applied directly and liberally in, on and around the ant nest so that it gets into the galleries and tunnels throughout the nest in order to permanently get rid of carpenter ants. Be careful around an ant nest as carpenter ants bite if threatened!

Having said that, it can be used effectively as non-toxic perimeter protection or sprinkled into areas which you want bugs to stay away from such as under mattresses on beds, between floorboards, lawns, etc.

Buying Diatomaceous Earth

DE is not something you can easily find anywhere. I ordered mine online. The main things to note are to NOT buy DE for swimming pools as that is a very coarse grade that will have NO effect on bugs. Just get something that is labeled as food grade or animal/pet grade. You also want to get a powder duster which is helpful to get the DE into holes and crevices as well as to spread it around more efficiently.

Hope this has been helpful! Leave a comment if you any questions or have had experience using DE and tell us the results.
