Pyrethrum 5 EC 250ml — Natural Pyrethrum Insecticide

Pyrethrum 5 EC 250ml — Natural Pyrethrum Insecticide

A naturally-derived insecticide based on pyrethrum (extracted from chrysanthemum flowers) — effective against almost all garden pests, leaves no toxic residue, and is safe for use on food crops when used correctly. Works in any grow system and with any substrate. The natural first-line pest control for growers wanting something stronger than soaps but gentler than synthetic pyrethroids like deltamethrin.

Why growers choose Pyrethrum 5 EC:

• Naturally-derived insecticide — pyrethrum extracted from chrysanthemum flowers, not synthetic
• Leaves no toxic residue — breaks down quickly in sunlight and air
• Safe for use on food crops — when label instructions are followed correctly
• Kills almost all garden pests — broad-spectrum action against most insect problems
• Works in any grow system and substrate — hydro, coco, soil all compatible
• Easy to use — dilute per label instructions, spray through standard sprayer
• 250ml concentrate — makes many litres of working solution

Who it's not for:

Important safety notes: Wear gloves and avoid skin contact during mixing and application. Toxic to fish and aquatic life — do not release into drains. Toxic to bees — do not spray in flowering outdoor gardens where pollinators are active. Do not use during flowering — while low-residue, best practice is veg-stage only. Degrades in sunlight quickly; apply at dusk or lights-off for maximum effect. Always read and follow label instructions. For severe persistent infestations, a stronger miticide (Vertimec) may be needed alongside.
