SUNYAYSUNYAY Diatomaceous Earth Powder Duster Multi-Purpose Powder Sprayer Indoor and Outdoor with Length Adjustable from 12" to 42"

I almost missed the most important part: the little clear bit of tubing that goes on the container top and sits in the powder. Once I installed that, the pressure was just fine and the duster worked perfectly!

Just what I needed to get the powder into the hornet nest. Good job!

Works well. Could be a little sturdier. For the price a good value.

Works well to get hard to reach areas

Works great. Using this to puff "Ant Powder" (0.05% Deltamethrin) into cracks in our house which harbor yellow jackets. This, of course, makes them angry, so do it early in the morning when it is cold. One day later, zero activity. I use it with the powder container upside down to get a bigger slug of powder to blow into the holes, but it works equally well upright. Well worth the price. No clogging, so far.

In September 2024, yellow jackets decided to build a nest inside my aluminum siding. I tried making a homemade trap using fruit juice and boric acid, but they weren't interested in it. I tried spraying boric acid into their narrow entrance, but that also had little effect. The wasps were flying in and out of my house like it was Grand Central.I then bought a few Rescue Wasp Trapstiks, a Dr. Killinger bulb duster and Delta Dust. That worked a bit but after a few days, the remaining wasps built a higher nest. I had to get serious or they would've built a stronghold in my siding. I bought Stryker 54 Contact Aerosol Pyrethrins spray and this Sunyay sprayer. The Dr. Killinger bulb duster worked OK, but I found myself having to lower it so dust can get into the stem, then raise it up to the nest to shoot. I felt like I was shooting minimal dust most of the time. It was like a Derringer, while the Sunyay was a Tommy Gun.I liked that Sunyay's dust chamber is separate from the bulb so you can turn the chamber upside down to get the most dust to shoot out. I was able to reach the higher nest hole and also effectively shoot into the other siding holes that I couldn't reach before. I was able to rapid fire into the siding and within a day, there was no more wasps flying in and out of my house. There were a few wasps who came to check out the nest, but they didn't enter the siding and just flew away. I guess they smelled the Pyrthrins spray or felt the Delta Dust and left.

Product arrived on time and in good condition!

I started with a puffer and moved to this hoping it would work significantly better but it did not. With the handle in one direction and the container on the bottom, you get a very very fine dry spray. Turning the container so it is on top, you get a heavy dose that empties the bottle in no time. There doesn’t seem to be any way to do what you need. However, if you don’t have too many bugs and you spray them individually, then this works OK but is an expensive way to deliver the product. I have one for borax and one for diatomaceous earth because I was trying to get rid of these horrible crickets that gobble my plants down to nothing. What works even better than either of these products is Dawn Power spray!
