Richgro Bug Killa 250g – Granular Systemic Insecticide for Ornamental Plants

Richgro Bug Killa Granular Garden Insecticide 250g

Richgro Bug Killa is a ready-to-use granular systemic insecticide for protecting ornamental plants against selected sucking insects and scarab beetle larvae. It is suitable for roses, azaleas, camellias, gardenias, magnolias, lilly pillies and other compatible ornamental plants grown in pots or garden beds.

After watering, the active ingredient moves into the soil and is absorbed through the plant’s roots. Feeding pests are then controlled as they draw sap from the treated plant. Visible control may take up to two weeks depending on the severity of the infestation.

How Richgro Bug Killa Works

The granules are activated when watered into the soil. The active ingredient is absorbed by the roots and distributed through the ornamental plant, providing systemic protection against listed pests.

Remove mulch and dead vegetation before application so the granules can contact the soil. Water immediately after treatment, but avoid saturating pots because excessive water may leach the product from the potting mix.

Application to Potted Ornamentals

Ensure the potting mix is moist before application. Measure the pot diameter and apply the granules evenly across the soil surface.

• Pots 100–200mm wide: Use 2.5mL from the supplied measuring cap

• Pots 201–250mm wide: Use 5mL

• Pots 251–300mm wide: Use 10mL

• 350mm pots: Use 10mL for plants up to 1 metre high

• 400mm pots: Use 15mL for plants up to 1 metre high

• For taller plants: Add 5mL for each additional metre of plant height

Water the granules into the potting mix immediately without overwatering.

Application to Garden Plants

For ornamental plants growing in the ground:

• Apply 10g per plant up to 1 metre high

• Add 6g for each additional metre of plant height

• Remove mulch and dead material from the application area

• Moisten the soil before treatment

• Spread evenly around the plant’s drip zone

• Water thoroughly to move the product into the root zone

Only reapply when reinfestation occurs. Do not apply more than twice within a 12-month period.
