  • Just what I needed! Works great!
Size: Small
About a month ago I repotted 5 of my 8 indoor houseplants. To my disappointment, the soil I had bought from the garden supply store was absolutely INFESTED with fungus gnats (I assume the eggs/larvae, not adults). If you’re not aware, fungus gnats are not just annoying, but their larvae eat fungus in the soil, but can also eat the roots of your plants which is really bad if it goes unchecked. Through all the research I’ve done, the most effective method seems to be using yellow gnat sticky traps, mosquito bit “tea” you water your plants with, and some people recommended a dusting of diatomaceous earth on the surface of the soil to kill the adults that are trying to get to the dirt to lay eggs. I’ve been using the traps and mosquito bit water and it’s made a difference. But I haven’t been using the DE since I didn’t have a way to dust it on my plants. So I bought this. I bought the small one and it was super easy to fill with the provided funnel, and very easy and simple to use. Every part of it feels high quality and will last for years to come. I also love the additional attachments it comes with particularly the tubing. When you dust your plants it’s important to not just get the soil but also on the tops and undersides of the leaves. The tubing helped me dust the undersides of the leaves, and it helped me reach through in through the plant to reach the soil (pictured). It’s kinda hard to tell in the picture but it has a light dusting of DE all over it. Even though the gnats only lay eggs in the soil, they can rest on the rest of the plant too so my hope is those ones will get killed by landing anywhere on the plant. I also had discovered aphids on that same plant so that’s also the other reason I dusted the entire plant and under leaves. I think I caught the aphids early enough and cut off the effected vine, so I don’t believe they will be as big of an issue as the gnats have been. But just in case it’s there lol. If you’re wanting to use DE on your plants for pest control, keep in mind if you water your plant it will wet the DE and won’t be useful. When the plant/soil dries out again, you will need to reapply the DE so it stays dry. It’s basically useless when wet. This little dusting bulb was a good investment though if even though it was kind of expensive. It’s useful for applications all over the house. But you get what you pay for and I think it’s worth it if you care about having something that will last for years to come. There are way cheaper options on Amazon but those I found, didn’t come with the mixing ball, funnel, and didn’t seem as good of quality and had a lot of negative reviews. I just got it today and only used it to dust my 8 house plants but so far I’m satisfied with the purchase and recommend it. I will be using it for months to come so if I have any problems with it I will update my review. If it’s not updated then everything works as it should lol. Last thing I wanted to mention is that DE can be slightly dangerous to inhale (just google side effects from long term DE inhalation). Doesn’t matter if it’s good grade or not. And when you’re dusting indoors it creates a cloud that takes a while to settle. So when filling the bottle or using it around inside your home, wear a mask just in case, and maybe leave the room and keep pets/kids away for a while until it settles . It probably won’t hurt anything if you don’t if you only use it a couple times here and there, and I’m sure you’d have to breathe in a lot of it to cause any substantial health issues, but just thought I’d mention it for those wanting to use a lot of it around the home (like for treating bed bugs for example). Once it’s settled though it’s not a danger to anyone as it stays on the floor or surfaces unless it’s disturbed. DE is also not dangerous to ingest as long as it’s the food grade kind. ... show more

  • Works Perfectly
Size: Small
Clear instructions. Very well built, brass parts fit together fantastically. Works well for tight spaces. I managed to get the DE up into recessed lighting to curb wasps with this thing. Great product.

  • Works well for boric acid distribution
Size: Large
Great for boric accid distribution. Great for getting behind and under areas where bugs like to live.

  • Not messy and reliable
Size: Large
I’ve tried a less expensive version of one of these bulb-blower type dispensers and the diatomaceous earth just leaked out the top. This one has metal on metal threads for a proper seal so no leaks when you squeeze it! It also has a funnel that fits like a cap over the bulb, so DE doesn’t get everywhere when filling it. The large ball bearing also prevents clogs and clumps within the bulb. I like the different tube options, which makes it really easy to reach all the places you might want to cover. I use this to dispense DE in and around my block fence and home for scorpions, and it works great for that purpose without covering my hands and me in DE in the process. ... show more

Very good quality, I'm happy with the product so far. The funnel is a life saver!! It takes some practice to get a good technique. Would recommend.

  • Dr. Killigan's Bulb Duster worked very well for me in my application.
Size: Small
I bought this on the recommendation of my brother to use for dusting a bee’s nest. I had never heard of a Bulb Duster before or using a powder to kill bees. I checked online for other makers of dusters and found many others at lower prices. Ultimately, I chose this manufacturer due to the recommendation of my brother. I had no issues with the order and delivery time was as promised at the time of ordering. My impression of this duster is that it is high quality and will last a lifetime. I really like the included funnel for use in filling the duster with powder. It sits nicely on the duster and covers the internal threads that the dust cap screws into. To fill the bulb, you hold it with the open end pointing up, place the funnel into the opening of the duster bulb and fill it with whatever powder you are using. There is a ball bearing that goes in the bulb that you use to break up any clumps or mix whatever powder you are using by shaking the bulb after you fill it, and the ball bearing moves around inside the bulb. It’s very much like the ball bearing inside of a can of spray paint. Everything about this duster has the feel of quality. I like the extension tubes that are included. I used both extension rods and the flexible tube to spray powder under the siding of my house where bees were accessing a nest. I was able to stand by the outside wall and bend the flexible tube upward to spray dust vertically up under the siding without having to crouch down or lay on the ground. The duster functioned without issue. A nice cloud of powder blasted out of the tube when I squeezed the bulb. I bought the smaller of the two sizes and find it more than adequate for my use. Based on my experience using this to spray/dust powder into an opening that bees were accessing, I recommend this for use. ... show more

  • Works, with some technique
Size: Large
3.75 Stars.... Just tried it using a new, unopened bottle of Sevin dust. I found that it clogs quiet easily which surprised me. Filled it 2/3 full. shook it, held it slightly downward and it clogged after one puff...had to unclog the tip several times. i was working a wasp nest so the clogging while i was puffing into the nest was a bit disconcerting...at most it would puff 2-4 times...puffing in a light to medium manner before it would clog up again. i tried a hard puff and it clogged instantly. i could understand if the dust had been sitting for a while..but it was a fresh bottle... i was a able to get enough and the next morning the wasp may were avoiding entry and by late day there was no activity (prior you'd see a wasp fly in/out every 30-40 seconds...). so job accomplished. build quality is very, very good. funnel is really helpful so as to not needing to use another one . will update review after using again, but the frequent clogging is an issue.... ... show more
