Yates Pyrethrum Insect Pest Gun 750mL – Ready-to-Use Natural Insecticide

Yates Pyrethrum Insect Pest Gun 750mL: Ready-to-Use Natural Insecticide

Yates Pyrethrum Insect Pest Gun is a ready-to-use, low-toxicity insecticide that kills a wide range of garden pests on contact. The "gun" is the built-in trigger sprayer, so there's nothing to mix or measure. You just shake and spray. It's based on natural pyrethrum from the pyrethrum daisy, works fast, and leaves no lasting residue, which is why you can pick and eat produce just one day after spraying. It suits vegetables, fruit trees, flowers, ornamentals and indoor plants.

What It Controls

It handles a broad spread of common garden pests, including aphids, caterpillars (cabbage moth included), thrips, whitefly, ants, earwigs, flies, leafhoppers and stink bugs. Because it kills on contact, it's at its best sprayed straight onto the pests, particularly the ones clustered on new growth or sheltering under leaves.

How It Works

The active is natural pyrethrins at 0.3 g/L, backed by piperonyl butoxide as a synergist. Pyrethrins are a fast-acting knockdown insecticide that work on contact by hitting the insect's nervous system, and the piperonyl butoxide stops the insect breaking the pyrethrins down, which speeds up the knockdown. It's non-residual: pyrethrum breaks down in sunlight and decomposes quickly, so it doesn't leave a lasting deposit on the plant. That's great for a short harvest window, but it does mean you treat the pests you can see rather than relying on lingering protection.

How to Use It

Shake the bottle well before use and keep it agitated as you spray. Cover the affected parts of the plant thoroughly, including the under-side of the leaves where many pests hide, since the spray only works where it lands. Spray when pests are active and first appear, and repeat if they return. Getting under the foliage is the single biggest thing that decides whether it works, so don't just mist the tops of the leaves.

When Not to Spray

Pyrethrum is easy to use but there are a few conditions where it either won't work well or can stress the plant. Don't spray when shade temperatures are near 30°C or higher, or when the soil is dry and plants are already suffering from moisture stress. Don't spray if rain is expected within about 2 hours, since rain washes it off before it can work. And spray only when bees aren't foraging, in the early morning or late evening, because it's toxic to bees.

Plants to Avoid

It's safe across most indoor and outdoor plants, but skip the delicate ones. Don't use it on sensitive indoor plants like African violets and maidenhair ferns, and don't apply it to young seedlings, all of which can be marked or damaged by it.

Harvesting After Spraying

The withholding period is short. Don't pick fruit or vegetables for one day after spraying, then wash your produce well before eating it. The quick breakdown that makes pyrethrum non-residual is exactly what keeps that harvest window down to a single day.

Bees, Fish and Safety

Pyrethrum is low in toxicity to people and pets, which is part of its appeal, but it isn't selective towards insects. It's toxic to bees, so time your spraying for when they aren't active and keep it off flowering plants they're visiting. It's also toxic to fish, so don't let it reach drains, streams or ponds, or drift near water. Keep children and pets away during application and until the spray has dried, and take extra care with cats, which are more sensitive to pyrethrins than most animals.
