It’s time to talk about diatomaceous earth applicators. I’m all for just using your hands, but sometimes an applicator is necessary. For dedicated diatomaceous earth diehards (alliteration!), it’s easier to have an applicator on hand. Especially when you need to apply a large amount of DE, sometimes using your hands DE doesn’t spread DE as evenly or widely.
With this said, not every applicator is of equal quality. There are some nicely designed ones, and then some not-so-nicely designed applicators: you generally get the feel for it once you start using it.
I’ve used a few different applicators. Additionally, I’ve waded through reviews to see what other people have said. Most of the reviews I took a look at were from Amazon. Just as a side note, I didn’t count the three star reviews because sometimes they were positive and sometimes they were negative. Seriously it was night and day.
This is one of the largest applicators you can use. It holds up to a pound of DE at a time. The hose is attachable, with the end piece turned upwards. This is useful for garden use and getting underneath leaves. I’ve always thought of this as an applicator you could use on the farm, but someone made the comment that you wouldn’t use a hose on a farm. It makes sense. There are industrial-sized applicators, for people who farm (possibly excluding hobby farmers) this might not be the best direction. The Dustin-Mizer works by using the crank. This could get tiring after some time. Out of 62 votes, only 11 of them were extremely negative.
- Hose at the end can be detached. Upward nozzle gets underneath things.
- Easy to put together.
- Built for larger applications.
- Light to carry.
- One of the more expensive applicators.
- Some of the negative reviewers questioned its construction.
- Can get clogged at times.
This little tool has an insulated tip at the end of a thin nozzle. It’s meant for very small applications, to get down into the details of a crevice. You would want this applicator for ant trails, seams, baseboards, window sills, outlets, cracks, and crevices. (If you’re wondering why the heck you need to put DE around outlets, then let me inform you that bedbugs can get in there. It’s quite gross.) This kind of applicator comes in handy. The B&G Duster is similar to this one, and is a little more professional. This one holds more DE, but that doesn’t matter too much when you’re looking for small applications anyway. One Amazon customer advised flipping it around saying that it dispersed more easily and evenly.
- Applies DE into areas that are difficult to reach. (If you can get a pencil eraser into an area, then you can get the JT Eaton Duster in.)
- 65% of reviewers found this applicator helpful.
- Under $20.
- Some people had problem with the spring-tension can be stiff making it difficult to squeeze.
I’ve only found this duster on DiatomaceousEarth.com, and it’s pretty cheap. It works as an all-round applicator that’s great to have on hand. It holds up to 7.5 oz of DE, which went a lot farther than I thought it would. I was also surprised at how far this applicator can spray the DE. At my job we have problems with ants sometimes so I used the Squeeze Duster to get them. It’s good because I could get kind of the weird, smaller areas. I wouldn’t use it for large applications, but this is one of the most simple, and efficient applicators for the price.
- All-around useful duster.
- Doubles as a container.
- One of the cheapest applicators.
- Sometimes I think it would be even more useful with an extension.
- Can only buy it from one location.
This one is nice because it functions the same as a the Dustin-Mizer, but it’s cheaper. They both hold the same amount of DE, and both have a nozzle that turns upwards. The main difference is that you pump the handle as opposed to turning a crank. A few reviewers suggested not filling the Gilmour Duster to capacity.
- Long, skinny nozzle is useful for many different areas. Especially useful in places like the garden.
- Similar to the Dustin-Mizer’s capacity and function but its cheaper.
- A useful tool for cracks, crevices, underneath plants, and similar hard-to-reach areas.
- Some reviewers complained that the duster would release some DE back on the user when pumping the handle.
This is a more professional-looking applicator, and it works in small cracks and crevices. Many people use it for dealing with a bedbug infestation because it’s easy to get along the seams and joints of the mattress. One major selling point for me on this item was the number of positive reviews to negative reviews. On Amazon, there were 75 four and five star reviews out of 79. Overall, it’s just a quality applicator.
- Perfect for bedbugs.
- Has three different plastic tips.
- Designed with a belt buckle.
- Some people had difficulty getting the DE into the actual bulb.
- Is one of the more expensive dusters considering its size.
