CSI 4-4 Mosquito Fogging Insecticide

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

City officials and pest control companies primarily use CSI 4-4 Insecticide to ensure targeted insects, such as the West Nile Virus, do not spread diseases. It is usually applied by truck-mounted thermal foggers to control 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 aerosol fogger is required. CSI 4-4 can be diluted or undiluted when used as a thermal or non-thermal fog. 

How to Use

• Step 1: Determine how much CSI 4-4 you will need, depending on what you use this product for and where and how you will apply it. To do this, calculate the square footage or acreage of the area you wish to treat. To find the square footage, measure the treatment areas' length and width in feet, then multiply them together (length X width = square footage). For acreage, divide the square footage by one acre (square footage / 43,560 sq. ft. = acres).
• 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 3 days (or 8.04 fl. oz per acre). ULV non-thermal aerosol (cold fog) and thermal aerosol fogging applications have a flow rate of 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 and 0.007 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 you apply 0.007 pounds of permethrin and PBO per acre. 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.

Many fruits and vegetables are approved to be applied with this product before harvest. The complete list is on the CSI 4-4 label.

When to Use

For best results, when CSI 4-4 Insecticide is used as a ULV non-thermal aerosol (cold fog) treatment, apply it 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 more significant than 1 mph but when wind speeds are less than 10 mph.

Safety Information

CSI 4-4 is safe to use around people and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when applying this product. 

Special Considerations

CSI 4-4 must be applied with 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 in a 3 day period.

This product cannot be mixed with water.

It may be applied undiluted or diluted. If you need to dilute it for specific application equipment you would mix CSI 4-4 with mineral oil.
