Label teardown
What the pack promises versus what the label chemistry actually is.
The marketing claim
“Destroys complete ant colonies without trace”
The chemical reality
Nippon Ant Killer Liquid is spinosad at 0.081% (CAS 168316-95-8) in a 25 g honey-sweet bait — Vitax SDS, not a spray. It is not Nippon Ant Killer Powder (permethrin dust) and not Provanto Ultimate Bug Killer (deltamethrin). Technical spinosad SC is a professional foliar insecticide: there is no sensible UK household bulk path that a householder can legally mix as ant bait. A 4 × 25 g pack of the same labelled liquid is the only honest stack.

The Marketing Claim & The Catch
A 25 grams pack of Nippon Ant Killer Liquid typically retails around £4.99 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: Destroys complete ant colonies without trace; Worker ants carry the bait back to the nest; and Useful where the nest site is unknown.

Proprietary Blend & Dosage Breakdown
The labelled active is Spinosad at 0.081%. Everything else in the pack is sugary honey-style bait (water, sugars; bittering agent).
At 0.081% 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 0.081% Amateur-labelled spinosad ant bait 0.081% (same liquid), mixed to Neat drops on a non-absorbent slip (3–4 drops per bait point).

The Active Chemical Alternative (Dupe Stack)
The dupe stack is Amateur-labelled spinosad ant bait 0.081% (same liquid) at 0.081% bulk. Indexed as CAS 168316-95-8, formula C41H65NO10 / C42H67NO10. Buy it as 100 grams (4 × 25 g) for around £12.46 from Amazon UK.
Working strength: Neat drops on a non-absorbent slip (3–4 drops per bait point). Indicative cost £0.25 per diluted litre — 35% 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 tube you buy. Gloves. Very toxic to aquatic life and hazardous to bees — keep bait off ponds, drains, food prep and open blossom.
- Place three to four drops on a clean slip of plastic, glass or metal beside the ant run. Do not heap. Leave workers to feed and carry the bait — do not spray or disturb them.
- Replace the slip daily until activity stops. 100 g of the same 0.081% liquid is four 25 g tubes without buying them one at a time.
- There is no sensible amateur bulk technical path. Do not dilute agricultural spinosad SC into homemade bait. Store labelled, away from children, pets and food.
- This is not permethrin ant powder, not deltamethrin foliar spray, and not a weedkiller.

Active ingredient and cheaper alternative — FAQ
Is this the same as Nippon Ant Killer Powder?
No. The powder is permethrin at 0.488% on talc (CAS 52645-53-1) — a pyrethroid contact dust for runs and nests. This liquid is spinosad (CAS 168316-95-8) in a sugar bait that workers carry home. Different molecule, different HSE number, different job. Never put either on skin.
Can I mix a homemade bait from agricultural spinosad?
No. 480 g/L spinosad SC is a professional foliar product, not an amateur ant-bait licence. Do not invent a sugar syrup from technical concentrate. Buy the labelled 0.081% bait a householder can legally apply — a multi-pack of the same tube is the only cheaper path.
How do you mix the Ant Killer Liquid dupe stack?
Biocide: read the HSE number on the tube you buy. Gloves. Very toxic to aquatic life and hazardous to bees — keep bait off ponds, drains, food prep and open blossom. Place three to four drops on a clean slip of plastic, glass or metal beside the ant run. Do not heap. Leave workers to feed and carry the bait — do not spray or disturb them. Replace the slip daily until activity stops. 100 g of the same 0.081% liquid is four 25 g tubes without buying them one at a time. There is no sensible amateur bulk technical path. Do not dilute agricultural spinosad SC into homemade bait. Store labelled, away from children, pets and food. This is not permethrin ant powder, not deltamethrin foliar spray, and not a weedkiller.
