Ant powder buying guide

Updated: 22 October 2026

Five amazon.co.uk tabs are open, every tub shows 4.4 stars, and the basket still feels like a guess. This ant powder buying guide separates those listings before you pay. Peter F., editor for DIY & tools at productscompared.co.uk, compared the pages captured on 19 October 2026 with the Nippon 150 g label and HSE’s pages on amateur biocides. No powder was laboratory-tested. A qualifying purchase can earn a commission at no extra cost to you. The scored rows sit on the [ant powder](/hub/pest-control/ant-powder) comparison. Open [best ant killer powder](/hub/pest-control/ant-powder/sub/ant-powder-best) only after the checks, if you still want one job.

What you are actually buying

Inside this set you are buying a householder dust, used only where that pack allows. Pestshield states 0.5% w/w permethrin on both packs. The Nippon 150 g label states 0.488% w/w under HSE No 5499. The Nippon and Zero In amazon files do not print a percentage, so that figure stays on the Nippon label. The gap is not proof the dusts behave the same on a wet step. A bait station is different, because the ant carries it home. Those stations were taken out of the table. If the basket says gel, you have changed method.

The checks, in order

Start with the pack. PestShield 150 g is £3.99 with 79 reviews in the raw capture. The three-pack is three stated 150 g bottles at £5.57, with 2,841 reviews. Nippon 150 g is £4.44 with 3,083 reviews. Nippon 300 g is £4.98 with 1,502 reviews. Zero In is £9.80 with 8,663 reviews. All five were 4.4 on 19 October 2026. Then read where you may use it, any puffer, the pet sentence and any duration. Both Nippon sizes state up to six months. Zero In states 12 weeks. Pestshield states neither. One 150 g tub fits one doorstep. After delivery, follow how to use ant powder.

150 g, 300 g, or a multipack

A B&Q page has shown Nippon 150 g at £6.09, 300 g at £7.94 and 500 g at £9.63. On this capture the 150 g was £4.44 and the 300 g was £4.98. The 500 g size is not one of these ASINs. Zero In B08XQLZYFB claims 45 m² and 12 weeks, and the pack count conflicts with a 450 g item weight. Follow the box.

The number on the label

An HSE number is the approval reference on that amateur product. The Nippon 150 g label prints HSE No 5499 and 0.488% w/w permethrin. The other four amazon files do not. A missing bullet is not proof a product is unapproved. Writing 5499 onto Pestshield or Zero In would invent a registration. Nippon’s bullets say children and pets need not be excluded. Zero In says keep cats away during application. Pestshield leaves pets unanswered. If a cat, a fish tank or a child shares the house, read is ant powder safe for pets.

Common questions

Is 150 g enough or do I need 300 g?
One 150 g tub matches a doorway or a single entrance when the label allows that surface. Nippon 300 g carries the same six-month claim with more powder, at £4.98 against £4.44 for the 150 g on this capture. Buy 300 g when you expect to treat a run of frames and cracks in one go. Buy the Pestshield three-pack when you want three stated 150 g bottles and you will use them, rather than store them.
Why do all the powders show 4.4 stars?
On the 19 October 2026 amazon.co.uk captures, all five listings sat at 4.4. The counts behind that figure run from 79 reviews to 8,663. A tied rating is why pack, pet wording, duration and the label number have to do the sorting.
Do Nippon 150 g and Nippon 300 g make the same claim?
Both state up to six months. The 150 g has more reviews in this set, 3,083 against 1,502, and it was cheaper on the capture. The 300 g is more fill for a longer stretch of slab or brick. HSE No 5499 and 0.488% w/w are documented here for the 150 g label. The 300 g amazon saved listing does not print that percentage, so the cardboard in the parcel is the place to confirm it.
What is an HSE number and which tub has one?
It is the approval number on an amateur biocide label. We can point to HSE No 5499 on the Nippon 150 g label PDF, beside 0.488% w/w permethrin. The Pestshield, Nippon 300 g and Zero In amazon saved listings in this comparison do not display an HSE number. When the parcel arrives, read the number on the pack you hold. A number from another brand’s paperwork is not a substitute.
Why does Zero In cost more if the stars match?
Zero In was £9.80, against £3.99 to £5.57 for the other tubs, with the same 4.4 and the largest review count at 8,663. The listing also states 12 weeks and 45 m², and it tells you to keep cats away during application. You pay for that combination, with an unresolved pack count still attached. Matched stars do not make it the same purchase as a £3.99 tub.
Which sentence about pets am I actually buying?
Read the bullets on the listing in the basket. Nippon says children and pets need not be excluded. Zero In says keep pets, especially cats, away during application. Pestshield does not answer pets in these saved listings. That sentence is part of the product. If you cannot live with it, change the listing before you compare grams.
