How Our Pyrethrum Insecticides Work
Kendon Pyrethrum-based solutions (also known as pyrethrin insecticide) are a natural, fast-acting and effective way to control pests. Derived from the dried flowers of Tanacetum cinerariifolium (pyrethrum daisies), these formulas work by disrupting the nerve function of insects by modulating the voltage – gated sodium channels, preventing the channels from closing and resulting in hyperexcitation which allows rapid paralysis and death within minutes of contact. They contain six active compounds—pyrethrins and related esters—which make it difficult for pests to develop resistance.
Key Features & Benefits
- Broad-spectrum: Effective against a wide range of pests, including flies, mosquitoes, cockroaches, aphids, and caterpillars.
- Rapid knockdown: Causes insects to fall over very quickly after contact.
- Natural origin: Derived from the chrysanthemum flower, making it a botanical insecticide.
- Repellent/exciter: Can also act as a repellent and causes insects to move more, which increases their exposure to the insecticide.
How should I mix and apply Kendon Pyrethrum?
Kendon’s pyrethrum range includes Pyrethrum SF Insecticide, Pyrethrum Insect Killer, Insect Destroyer and Pyrethrum Insect Dust, each with specific directions for mixing or applying. For best results, shake liquid products well before use, mix with water at the recommended rate, and apply as a fine mist spray to thoroughly cover affected plants, ideally at dusk or in overcast conditions to maximise effectiveness and slow UV breakdown. Pyrethrum Insect Dust is a ready-to-use dust that is applied directly from the shaker-top pack or a dust gun onto infested plants and areas, following the directions in the “How to Use” tables below and on the product label.

Is pyrethrin safe for use on edible crops and in home gardens?
Yes, when used as directed, these solutions are safe for edible crops and home gardens. Our formulations break down quickly when exposed to sunlight, leaving minimal residue. You can harvest treated vegetables just one day after application, making them ideal for growers and gardeners who value both safety and effectiveness. This one-day withholding period also applies to Pyrethrum Insect Dust (do not pick edible plants for 1 day after dusting), provided all label directions are followed.
What pests can I control with Kendon’s pyrethrin-based insecticides?
Kendon’s pyrethrin formulas effectively control a broad spectrum of common garden pests, including aphids, ants, caterpillars, leaf hoppers, glasshouse whitefly, thrips, and outdoors only for houseflies and cockroaches. These products are suitable for use on vegetables, ornamental flowers and roses, fruit trees, indoor plants and ferns. Pyrethrum Insect Dust also controls silverfish and potato moth in and around domestic and storage areas, and flies breeding in dust bins and compost heaps. For specific rates and directions for each product, see the “How should I mix and apply Kendon Pyrethrum?” answer above and always follow the label.
When and how often should I apply these solutions during the growing season?
Apply our solutions at 5–7 day intervals during crop growth, or more frequently during periods of heavy pest pressure. Spraying at the first sign of larvae or insect infestation helps minimise crop damage and keeps pest populations under control. Apply at dusk to slow breakdown and extend period of insect exposure. For Pyrethrum Insect Dust, apply when infestation occurs and re-apply every 5–7 days if required and insects persist, following the directions for vegetables, ornamentals, shrubs and other listed use areas on the label.
Can I mix these formulas with other garden products?
Yes, Kendon’s pyrethrum formulations are compatible with Triforine Rose Fungicide and Kanolacide Spray Adjuvant (canola oil). Mixing with an adjuvant can enhance spray coverage and slow down UV degradation, improving pest control results. Always follow label instructions for compatibility and safe use. Pyrethrum Insect Dust is a ready-to-use dust formulation and should be applied on its own, not mixed with water or other garden products, unless specifically permitted by the product label.
What is the withholding period after application on vegetables?
The withholding period for Kendon’s pyrethrin formulations is just one day. This means you can safely harvest and consume treated vegetables one day after spraying, provided you follow all label instructions. For Pyrethrum Insect Dust, do not pick edible plants for 1 day after dusting, in line with the label withholding period.
Why choose a natural insecticide over synthetic options?
Natural insecticides like pyrethrum offer quick knockdown of pests, minimal environmental impact, and low risk of resistance development. Pyrethrum breaks down rapidly in sunlight, leaving little residue, and is safe for use in organic gardening when used according to directions. Its broad-spectrum action makes it a versatile solution for both home gardeners and commercial growers.
What safety precautions and storage guidelines should I follow?
Always store pyrethrum insecticides in the original, closed container in a cool, dry place out of direct sunlight and out of reach of children. Do not spray or dust directly on humans, pets, exposed food, food preparation areas or food utensils. Avoid contaminating drains, sewers, streams, ponds and fish tanks with product or containers. Dispose of empty containers responsibly by wrapping in paper, placing in a plastic bag and putting in the garbage, and wash application equipment thoroughly after use. In case of accidental poisoning, contact a doctor or Poisons Information Centre immediately.
