MGK NyGuard IGR Concentrate 140 mL — Pyriproxyfen Insect Growth Regulator, Residual Control

MGK NyGuard IGR Concentrate is a pyriproxyfen-based insect growth regulator designed to interrupt the life cycle of more than 50 crawling and flying pests, preventing immature insects from maturing and reproducing.

Whether you're a pest control professional or a homeowner looking for a targeted, long-lasting tool, NyGuard delivers a different approach than fast‑kill insecticides. Instead of immediately knocking down adults, this concentrate mimics juvenile hormones so larvae and nymphs fail to develop into reproductive adults. Its photostable formulation and EPA reduced‑risk status for certain food handling sites make it suitable for indoor and outdoor integrated pest management programs.

How does NyGuard IGR stop pests from coming back?

NyGuard's active ingredient, pyriproxyfen, acts as a juvenile hormone analog that prevents immature stages of pests from completing development. Over several weeks, treated populations decline as new adults fail to appear, reducing reproduction and future infestations.

• Targets immature stages (eggs, larvae, nymphs) rather than relying only on adult knockdown.
• Effective against cockroaches, fleas, mosquitoes, ants, flies and 50+ species.
• Works as part of a rotation or in combination with adulticides for faster control.
• Produces residual control where breeding sites are treated.

Where can I safely apply this concentrate?

NyGuard IGR is labeled for use in both food and non‑food areas when applied according to directions, and its photostable chemistry resists breakdown in sunlight, allowing outdoor treatments at breeding sites. Always follow label instructions for rates, application sites and personal protective equipment.

• Suitable for kitchens, food storage areas and other commercial food handling locations (per label).
• Use around building perimeters, gutters, standing water, and landscaped areas outdoors.
• Can be tank‑mixed with compatible adulticides to address existing adult populations.
• Not a surface disinfectant—apply only to pest harborage or breeding sites as directed.

How do I mix and apply the 140 ml concentrate for professional results?

The product is a concentrate that must be diluted to proper rates based on the target pest and application type. Use calibrated measuring equipment and follow label mixing instructions; apply with a pump sprayer, backpack sprayer or low‑pressure mister for even coverage of harborage and breeding sites.

• Measure the 140 ml concentrate precisely and dilute per label directions for residual or broadcast treatments.
• Apply to cracks, crevices, wall voids, patios, standing water edges and turf that harbor immature stages.
• Combine with an adulticide when immediate knockdown of adults is needed (verify label compatibility).
• Wear recommended PPE and keep pets and people away until surfaces are dry.

Who is this for?

MGK NyGuard IGR Concentrate is built for pest management professionals, property managers, and homeowners running integrated pest programs who want science‑based, residual suppression of pest populations. It’s especially useful where preventing reproduction matters most—multiunit housing, food service environments, kennels, landscaped grounds and outdoor breeding areas—when used as part of a broader IPM strategy.
