## Description

desertcart.com : Dr. Killigan's The Insect Buster - Bulb Duster for Diatomaceous Earth and Other Powders - Effective Dust Application Tool - Small (8 ounces) : Patio, Lawn & Garden

Review: Just what I needed! Works great! - 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 desertcart 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.
Review: Great quality and easy to use - This works exactly as described. The bulb is sturdy and easy to squeeze. The tips let you get powder in tight spots and it gives a nice even puff every time. I have used it inside and outside and it performs well in both. The quality feels better than the cheaper options and I am glad I bought it.

## Questions & Answers

**Q: Is it made in the US?**
A: Hello, Thank you for your question.  Our Insect Buster is  designed and distributed from the United States and manufactured in China. Our goal is to work with both countries to bring the highest quality products to our customers to ensure peace in your home. Cheers!Vanessa and the Dr. Killigan’s Team

**Q: Would this work to disperse powdered sugar in a bee hive for varroa mites?**
A: Hello, Thank you for your question. Powdered sugar is a similar consistency of diatomaceous earth powder and you might see the same results with the Insect Buster but we can only stand by our satisfaction guarantee when our product is used with DE powder.

**Q: how far distance does it spray/spread? I want to go into a cellar with crickets and spray them from distance.**
A: It really depend on how hard you squeeze the bulb. For standard cracks and crevices, you won't have any problems distributing powder into them. If you are trying to hit a "target" from a distance, I'd say you'd be good to about 3-4 feet. Once you start squeezing too hard, the powder has a tendency to billow into a cloud more than maintaining a stream.

**Q: Can this product be used for wet dispersement of DE?**
A: Hello, Thank you for your question. When Diatomaceour Earth is wet it may be more prone to clumping making it harder to disperse. The Insect Buster does contain a metal ball to help break up clumps. You might see the same results with the Insect Buster but we can only stand by our satisfaction guarantee when our product is used with dry DE powder. Cheers! Vanessa and the Dr. Killigan’s Team
