Nyguard IGR Concentrate

Nyguard IGR Concentrate, manufactured by MGK, is an excellent juvenile hormone mimic that stops egg-laying and future adult activities of over 50 types of insects, both indoors and outdoors. 

With its active ingredient 2-[1-Methyl-2-(4-phenoxyphenoxy) ethoxy] pyridine 10.00%, this insect growth regulator works by getting to the root cause of the pest infestation—the eggs, larvae, and nymphs that turn into reproductive adults. Insects like cockroaches, ants, and mosquitoes that enter treated areas will result in abnormal growth development, leading to sterility or death upon contact and up to 7 months after application. 

Nyguard IGR Concentrate is an odorless insect growth regulator liquid that delivers excellent results for pest infestations with minimum risks. This broad-spectrum product may also be used with another non-IGR insecticide for broader adult pest coverage and to help reduce the overall pest population size. 

Tools Needed

Depending on your intended application method, apply this product with a pump sprayer, backpack sprayer, void injectors, carpet shampoo, paintbrush, roller professional foam applicator, ULV/fogging machine, or foaming sprayer. 

How to Use

• Step 1: Close the area to be treated and shut off ventilation systems before application. Determine how much Nyguard IGR Concentrate to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet, then multiply them together (length X width = square footage). Mix 4 ml of Nyguard Insect Growth Regulator per one gallon of water per 1,500 square feet for general broadcast, spot, or crack and crevice applications. You may also mix Nyguard Insect Growth Regulator with your chosen insecticide solution. Read the selected insecticide label for further mix rates and application methods.
• Step 2: Place half the required water into your selected spray tank device, then pour in the measured amount of Nyguard and fill the rest with the remaining half. Close the sprayer lid and shake to ensure even agitation.
• Step 3: Apply the solution as a coarse, wetting spray to labeled areas. Monitor the pest activity. Depending on the severity of your infestation, you may have to make repeat applications at 2—to 4-week intervals. Read all label directions for Nyguard and any pesticide you use along with this IGR to prevent overapplication. Ventilate treated areas before re-entry.

When to Use

Use this product as a preventative or when heavy insect activity can be seen. For best results, using this product with a pesticide that will kill adult pests (an adulticide) is better. 

Safety Information

Nyguard IGR Concentrate is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing or applying this product.

Do not allow children or pets to contact treated surfaces until the spray dries.

Special Considerations

Remember that Nyguard IGR Concentrate is an insect growth regulator, not a killing pesticide. This will prevent younger insects from maturing and sterilize adults. While this alone can be enough to control moderate infestations, it can take up to a month before you notice less activity. Use Nyguard with a pesticide that will kill adult insects to get control faster.

This product sterilizes adult insects rather than killing them, and it can take up to 4 weeks before you notice a dip in activity.
