Richgro Bug Killa Granular Insecticide

Keep your garden bug free with Richgro Bug Killa Granular Insecticide! A systemic granular insecticide to control a wide range of common garden insects!

Provides a minimum of 2 months of extended protection against a wide range of sucking insects on all your ornamental plants, including Roses, Azaleas, Camellias, Gardenias, and lilly pilly in the garden or in pots. Richgro Bug Killa is a systemic insecticide that is taken up by the plant’s roots to control pests. It also contains Iron and Zeolite which are beneficial to plant health, helping your ornamental plants grow taller and stronger, and making fertilizers more efficient.

Safer to use and more convenient than aphid and mealy bug sprays, Bug Killa is gentle on your plants. Choosing granules rather than a spray means there is no risk of scorching plant leaves on hot days, allowing you to give your plants complete protection against sucking insects even in the heat of summer. Watering after application increases penetration and allows faster take-up by the plant’s root system.

A 250g bottle treats up to 500 plants, making it an affordable and efficient solution for the home gardener. Its versatile nature makes it ideal for use in both garden beds and flower pots!

Will this product kill red spider mite too? Ian asked on 22 March 2025

Hey Ian,
Richgro Bug Killa Granular Insecticide is not specifically designed to target red spider mites. This product is primarily effective against sucking insects such as aphids, mealybugs, and scale insects on ornamental plants. Red spider mites, being arachnids rather than insects, typically require specialized miticides or different treatment approaches.

What does the instruction 2.5 g treats 10 x 3 litre pots actually mean? I can’t understand it. Gai asked on 9 March 2025

Hey Gai, The instruction "2.5g treats 3-litre pots" means that you should use 2.5 grams of the product to treat the soil in a pot with a capacity of 3 litres. Essentially, if your pot holds 3 litres of soil, you would sprinkle 2.5 grams of the insecticide evenly over the surface or mix it into the soil as per the product's application guidelines.

Does Bug Killa work on army worms and wooly aphids? The grubs are eating my Angels Trumpets and they’re relentless! The aphids are only infesting my Chinese Lantern at the moment and I am removing them by hand. White Oil kills them but it damages the leaves. Wendy asked on 14 February 2025

Hey Wendy,
Richgro Bug Killa Granular Insecticide is primarily designed to control a wide range of sucking insects on ornamental plants, such as aphids, mealybugs, and scale insects. It is not specifically labeled for controlling armyworms, which are typically found in lawns and are targeted by different products like Richgro Lawn Beetle & Grub Killa

How can I eradicate them effectively? I have way too many plants to spray them down individually. Something systemic for spidermites would be fabulous. Can I use this? Keely asked on 24 January 2025

Richgro Bug Killa Granular Insecticide targets a range of insect pests, but it is not specifically labeled for spider mites. Spider mites require a miticide or a systemic solution designed for their control. Always check the product label and consider consulting a local gardening expert for advice on systemic treatments for spider mites.

  5. Richgro Bug Killa is the best systemic insecticide I’ve found since Rogor was removed from the market.
    Bug Killa is very easy to use and a little dose goes a long way. It lasts for a couple of months and is effective against all sucking insects.
    Pestrol Australia were very easy to deal with and have the best price I could find.
    If you need a systemic insecticide, give Richgro Bug Killa and Pestrol Australia a go. You won’t be disappointed.
