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!

Q & A

Hi, Will this kill weevils on recently planted grape vines and how much do i use for each plant? Thanks Simon asked on 28 November 2024

Hey Simon,
Richgro Bug Killa Granular Insecticide is a systemic insecticide designed to control sucking insects on ornamental plants. Its active ingredient, imidacloprid, targets pests like aphids, mealybugs, and scale insects. However, it is not specifically labeled for controlling weevils on grapevines. For plants up to 1 meter in height, the recommended application rate is 10 grams per plant, with an additional 6 grams for each meter of height beyond that. Prior to application, remove mulch and dead vegetation, moisten the soil surface, and sprinkle the product evenly around the drip zone. Water as usual after application to incorporate the product into the root zone. This provides at least 2 months of protection.

It's important to note that Richgro Bug Killa is intended for use on ornamental plants and is not recommended for edible crops like grapevines. Using it on grapevines could lead to residues in the fruit, making them unsafe for consumption. For weevil control on grapevines, consider using products specifically labeled for such use, and always follow the manufacturer's instructions and local regulations.

Consulting with a local agricultural extension office or a professional pest control advisor can provide guidance tailored to your specific situation.

Does this work for lilly pilly beetles? If so how much would I need for plants in the ground 2 metres tall? Aleshia asked on 25 November 2024

Hey Aleshia,
Richgro's Bug Killa Granular Insecticide is a systemic treatment designed to protect ornamental plants, including lilly pilly, from various sucking insects. However, the product's label does not specifically mention its efficacy against lilly pilly beetles.

For plants up to 1 meter in height, the recommended application rate is 10 grams per plant. For each additional meter in height, add 6 grams. Therefore, for a 2-meter tall plant, you would apply 16 grams of the product. Prior to application, remove mulch and dead vegetation, moisten the soil surface, and sprinkle the product evenly around the drip zone. Water as usual after application to incorporate the product into the root zone. This provides at least 2 months of protection.

Always follow the product's label instructions and consider consulting with a local horticulturist or pest control expert for advice tailored to your specific situation.

  15. Worked great to kill the thrips I had on my Nepenthes. Completely harmless to the plants themselves, even the one that I accidentally gave a triple dose wasn’t bothered at all. I started to see a noticeable reduction after about 5 days, with complete elimination of all thrips after about 2-3 weeks. I’d recommend a micro-scale for dosages since for most potted plants you’ll likely be using 0.25 – 0.5 grams or less.

  19. This is gold! It’s taken 6 weeks but my thrips infestation is finally gone and my jasmine is thriving again. Before that I tried the normal methods I had on hand with no success; contact poison (pesticide spray) for something you can hardly see and mild deterrent (neem oil) didn’t do anything and more and more leaves were dying daily. Have treated the nearby plants, too, and no negative reactions by any of them. Sprinkle the goodness and water as long as the plants aren’t flowering 🙂
