Just what I needed! Works great!

Review Image by Jess
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

Could dust forever at a distancez safely

I never used a duster before. This xl size, with extra length of nozzles allow for a large amount of material to be loaded and can be used safely at a distance of about 16". The filler spout is nice to keep things clean too. I used delta dust in this to treat ground dwelling yellow-jackets. Last year we had a wasp nest in the block wall of our garage. They ate through the foam insulation and mortar. Spraying Bifenthrin directly inside the crevice (entrance hole) did not even reduce the activity. We called a professional, who used delta dust once. Few days later, the wasps were gone or dead on the ground. I added delta dust to my pest control inventory since. Midsummer of this year, i discovered 2 nests in the ground after mowing over them. Thankfully wasn't stung at all. Discovered a 3rd in the corner of our deck. Since I am a little bit of a scaredy-cat when it comes to stinging or biting insects, I wanted the most distance between myself and what's being dusted. Taped and zip-tied to a 4ft wood stick is a 1/4" vinyl tube. The extra tube fits snug over the curved brass tip and is taped so it won't slip off from the air pressure. The other end curves downward, right into the ground. At 5 ft+ away, I can safely observe and treat the hive entrance with minimal risk. This bellows bulb duster has enough pressure to project out of a 5ft vinyl hose to a distance over 4ft. Shake it and dust. The ball bearing is great to keep material from clumping and in creating the cloud of dust before it is sent out. I do all dust treatments either an hour after dark or just before any light exisit in the morning. PPE should be worn to reduce exposure when using the duster. I highly recommend this large bulb duster. It's rubber is soft and will always be reliable after use and washing. With that being said, there is only one problem I have encountered that isn't too much of an issue, but still a little bothersome. The screw in nozzle tends to unscrew itself from the top and then dust poofs out between nozzle and top. Teflon tape might help. Otherwise, I love this duster, and is well worth the money. ... show more

The right tool for killing nests in wall voids
Size: 14 oz
Very high quality tool and very effective at dispersing fine dust pesticides. Very good value. I know the company is all about the natural approach, but this thing combined with some Terro T600 is absolutely effective. I wiped out a wall void yellow jacket nest in about 24 hours with this thing. I'd buy it again. ... show more

Great for gardeners to rooting powder and sulfur dust
Size: 8 oz
It’s rare to find such a high quality and well designed product these days. I originally bought one for applying elemental sulfur powder to pruning scars to prevent fungal infection. It worked so well that I bought a second to keep loaded with rooting hormone to apply to cuttings. Haven’t tried with insecticidal powders yet but that will be next. ... show more

Superior Product
Size: 14 oz
I’ve had mine for several weeks now, and I’ve used it almost every day to puff Pyrethrin powder on Japanese beetles feeding on my Kentucky Wonder pole beans and grape vines. It works great! It’s nice when a product arrives and you find that it’s well designed, well made, and constructed from quality materials like brass and rubber. That’s the case with this product; there’s no plastic junk that will break or disintegrate after sun exposure and rough handling. I only wish I’d bought the smaller of the two sizes. The larger one I opted for works fine but the smaller might be a little easier to use with one hand. Due to the precision of dispensing powder, I’m able to avoid blossoms where pollinators feed, and I’ve only filled it up once, so no waste! ... show more

Great Product but Major Flaw
Size: 14 oz
This is very well made with quality materials. I know this will last a long time. It handled the diatomaceous earth so well and wouldn't want to use anything else. The details are very convenient. But it lost stars because for the price, this bundle should've included a scooper- especially one that could measure capacity of the squeezer (e.g. half a scooper = half full squeezer). Why is this important? Because you're putting the extra cost on your customers to buy a scooper/measure cup. The funnel is great but trying to pour it in makes a mess and wasteful, especially the bags that reseal for storage. Even if we can use our own kitchen spoons/cups, a cheap plastic one to leave in the bag specifically for what we're using is preventing cross contamination is a major oversight. Even spending this much for a duster was a stretch/luxury item for me. I don't need extra costs to use it. ... show more
