Label teardown
What the pack promises versus what the label chemistry actually is.
The marketing claim
“Kills ants and crawling insects on contact”
The chemical reality
Nippon powder is permethrin at 0.488% on talc — a pyrethroid crawling-insect dust in a 150 g shaker. A 1 kg bag of the same 0.5% permethrin powder is the same dust without the puffer-pack markup. It is not DEET, not glyphosate, and it is very toxic to cats and aquatic life.

The Marketing Claim & The Catch
A 150 grams pack of Nippon Ant Killer Powder typically retails around £3.50 in lawn & garden. That is a UK shelf-price snapshot for the maths on this page — not a live shop quote or a manufacturer RRP. Listings, sizes and deals move. The marketing line is that you are buying a finished lifestyle product, not a weighed chemical.
On the pack: Kills ants and crawling insects on contact; Up to six months’ control indoors and outdoors; and Also for wasp nests.
The catch: Nippon powder is permethrin at 0.488% on talc — a pyrethroid crawling-insect dust in a 150 g shaker. A 1 kg bag of the same 0.5% permethrin powder is the same dust without the puffer-pack markup. It is not DEET, not glyphosate, and it is very toxic to cats and aquatic life.

Proprietary Blend & Dosage Breakdown
The labelled active is Permethrin at 0.488%. Everything else in the pack is talc dust.
At 0.488% active, most of what you pay for is carrier and packaging. The brand is selling convenience, fragrance and a label — not a uniquely potent molecule.
Branded working strength is whatever comes out of the bottle. The bulk alternative is 0.5% Permethrin 0.5% crawling-insect powder, mixed to 8 g/m² light dust on runs and nest entrances.

The Active Chemical Alternative (Dupe Stack)
The dupe stack is Permethrin 0.5% crawling-insect powder at 0.5% bulk. Indexed as CAS 52645-53-1, formula C21H20Cl2O3. Buy it as 1 kg for around £12.99 from Amazon UK.
Working strength: 8 g/m² light dust on runs and nest entrances. Indicative cost £0.10 per diluted litre — 44% below a typical branded pack on a per-litre basis, before you reuse leftover bulk.
Follow the mixing method and the supplier SDS. Wear the listed PPE. Do not mix incompatible oxidisers, acids or ammonia.
- Biocide: read the HSE number on the powder you buy. Gloves and a dust mask when puffing. Very toxic to aquatic life — keep off ponds, drains and fish tanks.
- Cats are highly sensitive to permethrin. Keep treated dust away from cats, cat bedding and grooming areas. Keep children off until the powder has settled.
- Puff a thin 8 g/m² film along ant runs, cracks and nest entrances. Do not heap. 1 kg at that rate covers about 125 m² of run — more than eight 150 g Nippon shakers.
- Buy 0.5% ready-to-use permethrin crawling-insect powder a householder can legally apply. Do not invent a stronger mix from agricultural concentrate.
- Store dry and labelled. Sweep up excess from indoor floors; do not wash it into a gully.

Active ingredient and cheaper alternative — FAQ
Is this the same as Autan DEET spray?
No. Autan Tropical is DEET on skin (CAS 134-62-3). Nippon is permethrin dust (CAS 52645-53-1) for ant runs and nests. Different molecule, different use, different hazards — never put ant powder on skin.
Can I use this on the lawn for daisies?
No. Permethrin is an insecticide. Lawn weeds are a selective herbicide job (mecoprop-P + dicamba) — see the Doff concentrated lawn weedkiller teardown.
How do you mix the Ant Killer Powder dupe stack?
Biocide: read the HSE number on the powder you buy. Gloves and a dust mask when puffing. Very toxic to aquatic life — keep off ponds, drains and fish tanks. Cats are highly sensitive to permethrin. Keep treated dust away from cats, cat bedding and grooming areas. Keep children off until the powder has settled. Puff a thin 8 g/m² film along ant runs, cracks and nest entrances. Do not heap. 1 kg at that rate covers about 125 m² of run — more than eight 150 g Nippon shakers. Buy 0.5% ready-to-use permethrin crawling-insect powder a householder can legally apply. Do not invent a stronger mix from agricultural concentrate. Store dry and labelled. Sweep up excess from indoor floors; do not wash it into a gully.
