Best depends on the job

A shared 4.4 does not rank these powders. Expert Reviews, updated on 1 May 2025, named a Nippon 300 g and a low-priced Zero In at other retailers. Those prices are not this amazon.co.uk shelf. Every powder here is a householder permethrin dust, not a bait station. If the ants must carry food home, read ant powder versus ant bait first. A visible nest, a doorway, the lowest single price and the longest review file are different purchases. Both Nippon sizes state up to six months. Pestshield states no duration. Zero In states 12 weeks. Rain clumps or washes the dust on all three brands.

A nest, a doorway, a single tub, a long review count

Choose Nippon 150 g for the six-month claim, 3,083 reviews and £4.44 on the 19 October capture. Leave it if the amazon page must show a puffer or a percentage. The 0.488% w/w figure is on the Nippon 150 g label, HSE No 5499. Nippon 300 g makes the same claim at £4.98 with 1,502 reviews, when a small tub would run out. Neither size belongs on a worktop. The Pestshield three-pack is three stated 150 g bottles at £5.57 and 2,841 reviews, both at 0.5% w/w permethrin. PestShield 150 g is £3.99 with 79 reviews, too thin a file to call best-reviewed. Choose Zero In at £9.80 with 8,663 reviews if you will keep cats away while you apply it. It states 12 weeks and 45 m², and the pack count conflicts with the item weight. The checks are on the ant powder buying guide.

What the round-ups are not measuring

Expert Reviews priced Nippon 300 g at £7.94 at B&Q and Zero In 300 g at £3.48 at Toolstation, with a 15 m² claim. That is not this shelf. Listing B08XQLZYFB was £9.80 and claims 45 m² and 12 weeks. Follow the box in your hand. Reviewers mention loose caps and rain, and one Nippon 150 g buyer said the ants ignored the dust.

Skip it if the label does not match the room

Zero In’s listing tells you to keep pets, especially cats, away during application. Nippon’s bullets say children and pets need not be excluded. Pestshield does not answer pets. PestShield 150 g says keep the tub away from children and off food-contact areas. The Nippon 150 g label keeps dust out of food, covers fish tanks and water tanks, and keeps the contents out of drains. A six-month claim does not lift those lines. Council pages disagree with using powder and liquid together, so that suggestion is not a method.

Common questions

Which ant powder is best for a nest under paving?
Nippon is the conditional pick when you can see the entrance and you want the six-month claim that both Nippon sizes state. Dust only where that label allows, on a dry surface. Leave Nippon if you need a percentage or a puffer printed on the amazon page. Zero In is the alternative when you want 8,663 reviews and you will keep cats away while you apply it. Its duration line is 12 weeks, which is a shorter claim than Nippon’s.
Which is best if I only need a doorway?
PestShield 150 g at £3.99 is the lowest single tub on this snapshot, if you can accept 79 reviews in the saved listing. Nippon 150 g at £4.44 is the doorway pick when you want the six-month line and a much larger review count. The three-pack is spare powder you may not open. A doorway still needs a dry sill. Rain is the reason reviewers say they had to lay the dust again.
Is the most reviewed one the best?
Zero In has the most reviews in this set, 8,663, and the same 4.4 stars as the other four. That volume is a reason to read the listing. It is not a reason to ignore the pet sentence or the unresolved pack count. Nippon 150 g has 3,083 reviews at a lower price, with a longer stated duration. Best, on this page, means best for a job you can name.
Is the cheapest 150 g a false economy?
PestShield 150 g costs less per tub than Nippon 150 g on this capture, £3.99 against £4.44. It can be enough for one dry doorway when the label matches the surface. It is a weak buy when you needed a stated duration, a large review file, or a clear pet sentence, because those are the gaps on that listing. The three-pack works out as more stated powder for the money if you will use three bottles.
Should I buy Nippon 150 g or 300 g if both claim six months?
Both state up to six months. The 150 g is £4.44 with 3,083 reviews. The 300 g is £4.98 with 1,502 reviews. Buy the 300 g when the length of slab or frame would empty the smaller tub. Buy the 150 g when one entrance is the job and you want the heavier review count. A heavier tub does not extend the six-month claim.
