Monarch G Insecticide Granular

Monarch G Insecticide – Granular Lawn Grub & Ant Control

Professional pest control made simple.
Monarch G Insecticide delivers long-lasting control of Argentine Stem Weevil, Mole Cricket, Ants, and Ant Nests in lawns, playing fields and commercial turf. Formulated with Fipronil (0.5 g/kg) in an easy-to-spread granule, it targets pests where they live — in the soil — for effective, season-long protection.

This Group 2B insecticide moves into the soil profile after watering, stopping damaging pests before they can reach the roots. Ideal for use in high-value turf areas or home lawns where lawn grubs and ant mounds cause surface damage or stress.

How much to apply:

• Argentine Stem Weevil: 1.5 kg per 100 m²
• Nuisance Ants: 1.2 kg per 100 m²
• Mole Crickets: 0.6 kg per 100 m²
  Apply evenly with a granular spreader and water in immediately with at least 6 mm of irrigation to activate. For nesting ants, treat mounds directly and the surrounding area (~100 m² radius).

Monarch G provides fast knockdown and residual control, helping maintain healthy, undamaged turf surfaces across all lawn types.
