Best wasp spray UK for a nest or for flies indoors

Updated: October 2026

You want one named can, and the star chart on amazon.co.uk points at the wrong job. The best wasp spray UK question in this set has two answers, because a nest and a kitchen are not the same purchase. The Raid six-pack leads on stars and is an indoor spray. Zero In Ultra Power is the only nest foam, and it sits lower. The [wasp spray comparison](/hub/pest-control/wasp-spray) holds the full table. Here each listing gets a person it suits and a person who should leave it. We did not run a lab test. A qualifying purchase can earn a commission at no extra cost to you.

Best for a nest you can see

For a nest you can see, the candidate in this set is Zero In Ultra Power 600 ml, model ZER556, listed at £12.94. The title says a trigger foam, up to 4 metres, and 4 to 7 nests. That is the only row with a nest claim. The can in your hand is the reach that counts, and the argument about jets is on wasp nest killer foam.

Best attested indoor spray

The top pick for flies and a wasp already indoors is the Raid six-pack, model 92880, £19.99 in the extract, 4.6 from 6,783 reviews. The smaller Raid, the duo, is £8.70. Its title says 2 × 300 ml and its volume field says 100 ml, so buy it only if the box matches the duo line. Room smell, pets, and the 15-minute leave are on indoor fly and wasp killer.

The cheap multipack and the no-brand can

Sanmex is the best value on price in this set: £6.22 for a title of 3 × 300 ml, 4.1 from 4,018 reviews. The target-species field says Ant. That conflict is why the value badge is a price bet, not a clear wasp specification. The unbranded three-pack is £12.85, with no brand in the technical block. A USDA line is not an HSE number. The route choice is the wasp spray buying guide.

Who should buy none of them

Buy none of them if anyone in the house might be allergic. The British Pest Control Association treats that as a reason not to start. Buy none of them if the nest is above head height. A longer title on a foam can does not cancel Leeds' head-height line. Buy none of them for honey bees, which HSE treats as a last resort for insecticide, or for a suspected yellow-legged hornet, which you report with a photograph rather than spray.

Common questions

Which can is best for a nest?
In this set, Zero In Ultra Power 600 ml, ZER556, at £12.94. It is the only foam with a nest claim, a stated reach of up to 4 metres, and a trigger. Skip it when you cannot see the nest, when it is above head height, or when anyone might react badly to a sting.
Which is best for flies and a wasp indoors?
The Raid six-pack, model 92880, at £19.99 in the extract, 4.6 from 6,783 reviews. The duo at £8.70 is the smaller Raid if the cans you receive match the title. Neither is a nest foam. Wasps in the reviews often take longer to drop than flies.
Is the Raid six-pack the test winner because of 4.6?
The 4.6 is an amazon.co.uk average, not a laboratory prize. It is the highest score in our weighting because of those stars, 6,783 reviews, a named model, and a job the bullets actually describe. The badge on the comparison is the machine value for that top pick. It does not mean the six-pack kills a colony, and it does not mean a cheaper can has failed a lab.
Is Sanmex good enough if Raid costs more?
Sanmex at £6.22 is the best value if you want a cheap indoor fly spray and the physical label matches a fly-and-wasp aerosol. Reviewers often say it is weaker than Raid. The listing's target field says Ant, so it is not good enough as a nest product, and it is a weaker bet than Raid if you need the page to agree with itself. For a visible nest it is the wrong shape at any price.
Why is the nest foam rated lower?
Buyers argue about the jet. Praise for a quiet nest by morning sits next to reports of a short spray, a dribble, and a second can, across 5,173 reviews at 3.6 stars. That is a different complaint from the flies still in the kitchen, which is what the Raid reviews mostly discuss.
Should I buy the 300 ml foam instead of the 600 ml?
Not from this table. A 300 ml Zero In is a different model, with its own reach and treatment count, and it is not one of the five listings. Trade prices around £4.99 to £5.52 in October 2026 were for that smaller can. If you are choosing inside this comparison, the nest row is the 600 ml Ultra Power, with the jet checked on the tin you hold.
What should I skip if the nest is in a wall?
Skip every can here. You cannot see the nest, so foam stops at the opening and a fly spray does not travel into the cavity. Blocking the hole can push wasps inside. That job is powder, which we did not compare, or a council visit or a BPCA member. Leeds' £76 figure is one council's fee, not a quote for your wall.
