Ready to use

Pyrethrum is the perfect pest control solution for your home-grown vegetables as well as the ornamental garden. The naturally derived insecticide will knock insects flat! It's the ideal product to ensure your vegetables and other edibles are pest-free.

When to use



Low toxicity

Pyrethrum is not a scheduled poison - it poses very minimal risk to humans, animals and birds. No protective gear required

Non-residual, non-systemic

Does not remain on, nor is it absorbed by plants. It doesn't enter the food chain or accumulate in the environment. It is easily washed off.

Spray today, eat tomorrow

Wait just one day after spraying edibles with Pyrethrum before picking or eating. Rinse in fresh water after harvest to wash away any residue

Effective against ants

Pyrethrum is highly effective at stopping ants - it literally kills them in their tracks.


Suitable For

Control of common insect pests including azalea lace bug, aphid, whitefly, scale, thrips, mealy bug and leafhopper on ornamental and edible plants in the garden or indoors

Not Suitable For

Do not use on very young seedlings or very soft, new foliage (it may result in burning)

Do not spray directly on to humans, pets, exposed food, food utensils or food preparation areas

Do not spray if it is raining or about to rain, windy, unusually hot or if plants are wilting

How to Use

The active ingredient in Pyrethrum works by killing insects that come into immediate contact with it.
