Mosquito fogger Model 870 Mister Duster Mosquito Sprayer Backpack Sprayer Cold Fogger

Concerns about weight are legitimate. It's 60 pounds with a full tank of fuel and pesticide, making it cumbersome to put it on your back. A pedestal or tail gate are good solutions for that once it's started. Works great though. Mosquitos are more than plentiful at a home on the water. Using this fogger with a Bifenthrin product eliminates almost every insect for an extended period. Assembly requires just a little more mechanical knowledge than what's in the instructions, but overall it's very straightforward. Runs great. Very satisfied with the product. Buy a mask.

I have now used this system since last June 2025. We had a warm early Nov so I used for the final time. I began my next treatment in early April. When I stored my machine I added 1 oz of each Ethynol shield and Mechanic in A Bottle. It cranked on the 2nd pull. I spray every 3 weeks with exceptional results. The company provide excellent service and extra parts that will probably be needed in the future. The only other part I wish they had included is the atomizer unit on the end of the tube. This is a terrific it. I have several friends who have purchased one on my recommendation and they love it.

So far so good. The other reviews are right. This is very heavy. I have to set it on a bench and the put it one. It’s top heavy and backward to put on normally. I’m 6-2 230 and lift weights all the time and I struggle with it. If your an older lady or gentlemen just be aware you will need help putting it on. The motor cranks easy.

a good machine once adjusted right

I have to admit I was a bit skeptical. I was looking at a $2000 Stihl fogger then saw this one on Amazon. We have really bad mosquitos and are surrounded by woods. After assembly I mixed up the 2cycle gas/oil, primed the bulb 10 times, closed the choke and it started on the second pull with no carb Adjustments ( Wisconsin sea elevation). I let it idle for 20 -30 minutes to break in the engine. Now, I set the flow meter ( near the throttle trigger to "1") on the first test and it was prefect for 4 gallons covering 10,000 sq feet of bushes and trees. here's the challenge! The fogger only weighs 25lbs but with 4 gallons you're now at 60lbs!!! So put it on the back tail gate of a pickup or a folding table, sit on a stool, strap in, adjust straps ( while it's running) be careful standing up because the first few steps will be like a drunken sailor!!! It takes a bit to get your balance because it's very top heavy. It worked very good blasting a fog 20-30 feet deep into the woods. ( do not use gas containing ethanol, it will destroy the carb). It seems very well made and I'm happy with it.
