CSI 4-4 Insecticide by Control Solutions Inc. is a ready-to-use mosquito fogging solution with 4.6% Permethrin and 4.6% Piperonyl Butoxide. It can be applied as a cold-fogging or as a thermal-fogging solution to provide a fast knockdown and residual control of mosquitoes and other flying insects.

CSI 4-4 Insecticide is primarily used by city officials and pest control companies to ensure that targeted insects do not spread diseases, such as the West Nile Virus. CSI 4-4 is usually applied by truck-mounted thermal foggers for control of flying insects over large areas, such as neighborhoods or golf courses, and is safe to apply to various crops.

Tools Needed

To apply CSI 4-4, a handheld ULV fogger, truck-mounted ULV fogger, or truck-mounted thermal aersol fogger is required. When used as a thermal or non-thermal fog, CSI 4-4 can be applied either diluted or undiluted. 

Professional Fogging Vegetation

How to Use

  • Step 1: Determine how much CSI 4-4 you will need, depending on what you are using this product for, as well as where and how you will be applying it. To do this you will need to calculate the square footage (length x width = square footage) or the acreage (Square footage /43,560 = acreage) of the area you wish to treat.
  • Step 2: CSI 4-4 can be applied either Undiluted or diluted with mineral oil. The maximum amount of Permethrin and Pipronyl butoxide (PBO) allowed is 0.007 pounds per acre in a 3-day period (or 8.04 fl. oz per acre). For both ULV non-thermal aerosol (cold fog) and thermal aerosol fogging applications, the flow rate is between 2.28 and 16.08 ounces per minute at an average vehicle speed of 10 miles per hour. These rates are equivalent to 0.001 (1.14 fl. oz.) and 0.007 (8.04 fl. oz.) pounds of permethrin and PBO per acre. Use the higher flow rate in heavy vegetation or when populations are high. CSI 4-4 can also be diluted with a solvent-like mineral oil so you don't exceed the maximum weight of the active ingredients per acre.
  • Step 3: Apply CSI 4-4 at a flow rate of 16.08 fluid ounces per minute with a vehicle speed of 10 mph when using a truck-mounted fogger. This will ensure that you are applying 0.007 pounds of permethrin and PBO per acre. For backpack or handheld applications, you will want to apply CSI 4-4 at a rate of no higher than 0.007 pounds of permethrin and PBO per acre (2.68 fl. oz. per acre). Use a walking speed of 2 mph and a 300 feet swath width. Direct the mist to the air, foliage and harborage areas where mosquitoes and other flying pests are found.

Where to Use

When used as an ultra low volume (ULV) non-thermal aerosol (cold fog) application, CSI 4-4 can be used on athletic fields, campsites, gardens, golf courses, municipalities, overgrown waste areas, parks, playgrounds, recreational areas, residential areas, and woodlands.

There are a number of fruits and vegetables that are approved to be applied with this product before harvest. Refer to the CSI 4-4 label for the full list.

When to Use

For best results, when CSI 4-4 Insecticide used as a ULV non-thermal aerosol (cold fog) treatment, apply when the weather conditions will keep the fog low to the ground and when the insects are most active, which is usually in the early hours of the day or later in the evening when temperatures are cool. Apply when air temperatures are over 50 degrees Fahrenheit. Apply when ground wind speeds are great than 1 mph, but when wind speeds are less than 10 mph.

Safety Information

CSI 4-4 is safe to use in public areas when applied according to label directions. This pesticide is extremely toxic to bees and aquatic organisms. Do not apply over bodies of water, or when wind speeds exceed 10 mph. See CSI 4-4 label for a list of approved fruits and vegetables that are allowed to be applied with this product before harvest.

Special Considerations

CSI 4-4 has to be applied with ultra low volume (ULV) and thermal fogging equipment. It cannot be applied with a pump sprayer or spray rig. Do not treat a site with more than 0.007 lbs of each active ingredient per care ina  3 day period.

Good stuff
Works good i found timing is everything, it appears to be a contact spray, you need to spray about dark or after when they're out in full force. i don't get good results if i spray to early or even at night if the Mosquito's aren't flying. I've been using this spray for years its good stuff!

Great Fogging product!
Very impressed with how well CSI 4-4 worked to kill a mosquito swarm on a large landscape. Solutions shipped it to me fast and I got right to mixing it and applying it to knockdown a large swath of mosquitoes. Will keep using it and buy another when it's done.

Skeeter killer works great.
The Skeeters are real thick around the lake especially while the humidity has been high. Fogging with CSI 4-4 would last about 3 days until the Skeeters needed to be fogged again.

Work very well!!!
I live in eagle lake, TX where we are known for our mosquitoes because of all the rice fields here. I’ve been plagued with mosquitos for years. Just recently I purchased a commercial thermal fogger. I treat my 5 acre yard twice a week. I was skeptical About it working but I had to at lease try something. To my amazement the mosquitoes seem to vanish!!!??
I don’t usually write Reviews but this stuff just works! I will continue to use this product.
Thanks

I have used this product for many years. Have never had any problems. found it to be very effective in a barrier spraying program for the farm I managed. I recommend it all the time to folks who ask as they are impressed with the lack of mosquitos in area around the farm.

No more mosquitoes. Wear shorts in the evening!
Product works amazingly well. We use it 7:1 with diesel in our gator mounted fogger. We drive about walking speed. A little goes a long way. Shop around for price. We usually fog 2 sunsets in a row and then again in 10 days.

Mosquito fogging
I used the product for fogging mosquitos on 5 acres. Works well and I use it around the barn and horses. The product doesn't really do much for flies and doesn't really hold up to weather but does make a big difference when used regularly.

Questions and Answers

  1. Q:Can this product be diluted with water instead of mineral oil. I have a tomahawk backpack fogger with a 3.7 gallon tank. I also need to know how much product I can use to make up the 3.7 gallon tank
    5/1/24
    A:It cannot be mixed with water. Since you are using a backpack fogger the easiest way would be to use it straight (undiluted) and fill the 3.7 gallon tank completely with CSI 4-4 Mosquito Fogging Insecticide.

  2. Q:Will this product work in a Ryobi electric fogger? Also, down here in Florida we have a major problem with no-seums. Will this work on them?
    12/5/23
    A:CSI 4-4 Mosquito Fogging Insecticide will control biting midges, which is what no-see-ums are considered. Its best to speak to the manufacturer for the type of fogger you have. This product can only be used with foggers like ULV Non-Thermal Aerosol (cold fog) and thermal aerosol fogging equipment.

  3. Q:Does this Ship to Canada ? It appears it can be used in a propane thermal fogger ?
    6/3/23
    A:CSI 4-4 Mosquito Fogging Insecticide cannot be bought or shipped to Canada. Each states department of agriculture regulates the use of certain chemicals within products, which may not be approved of in certain countries like Canada. It would be best to check local stores in your area as those products are approved to be used in your region.
