Particle Baits: A Complete Guide

By Alex Clayton · Updated 23 October 2026

One guide tells you to boil tiger nuts for 30 minutes. Another says an hour. Both sound certain, and you’re left with a bucket of rock-hard nuts and no idea who to believe.

Particle baits are seeds, nuts, pulses and grains: hemp, maize, tiger nuts, chickpeas, tares and sweetcorn. Unless they come tinned or ready-prepared, you soak them, then cook them until soft, before any go in the water. Get that right and carp particles are some of the cheapest baits you can feed in quantity.

This guide covers what particles are, how to prepare particles safely, soak and cook times side by side, a simple particle mix, how much to feed, how to store what you cook, and the fishery rules that catch people out.

What Particle Baits Are and Why Fish Eat Them

A kilo of prepared hemp costs a fraction of a kilo of quality boilies, and it can hold feeding fish on a spot for hours.

A particle is any small seed, grain, nut or pulse fed in quantity. The common ones each do a different job:

Hemp: the attractor. Small, oily and too small to hook on its own.
Maize and tiger nuts: hard, hookable and selective.
Sweetcorn: cheap, universal and ready to use from the tin.
Tares, chickpeas and maple peas: extras for variety.

Particles work through numbers. Hundreds of small items keep fish grubbing on one spot for longer than a handful of big baits, and because each item is tiny, fish don’t fill up quickly. Tiger nuts add selectivity: most nuisance fish ignore them, while small fish will happily strip a hook of sweetcorn.

Particles are most associated with carp, but they also suit tench and bream.

Against boilies, particles cost less but need a day or two of planning, and some waters restrict them (see the rules section below). Browse our full bait guides for the alternatives.

How to Prepare Particles: Soak, Cook, Then Squash Test

One test settles almost every particle. Take a cooled grain or nut and squeeze it between finger and thumb. If it squashes, it’s ready. If it doesn’t, keep cooking.

That test is the core of how to prepare particles. The steps around it:

Measure the dry particles into a bucket with room for them to double in size, and cover them well with cold water.
Soak until they stop swelling. That’s typically 12 to 48 hours depending on the bait (the table below gives each one).
Simmer or boil in fresh water until they pass the squash test. Hemp is the exception: stop once most seeds have split and the white shoot shows.
Cool them quickly and keep them in their own liquid.
Never add dry particles to a mix on the bank.

Soaking and cooking do different jobs. Soaking lets the particle take on water, and that’s what stops it swelling later. Haith’s accepts that properly soaked maize swells enough to be safe unboiled, but still prefers to boil it. Cooking softens particles and, by the usual reasoning, makes them easier for fish to digest, so do both.

Expect published times to disagree, sometimes on the same website. Fishing Again’s two guides give tiger nuts a 24 to 36 hour soak and a 30 to 40 minute boil on one page, and a 48 hour soak and a 45 to 60 minute boil on the other. No official standard exists. If you’re unsure, soak and cook longer, never shorter.

Short of time? Haith’s describes a pressure-cooker route for maize: a few hours’ soak and about 15 minutes’ cooking (follow your cooker’s instructions). Ready-prepared jars and pouches, and tinned sweetcorn, skip the work entirely. Some waters accept only shop-bought prepared particles anyway.

Our guide to bait preparation and storage covers the wider process for every type of bait.

The Main Particle Baits Compared: Soak and Cook Times

Why does one writer give tiger nuts a 20 minute simmer and another a full hour? Nut batches, water and heat all vary, so treat every time below as a range and finish with the squash test.

Particle	Soak	Cook	Done when	Best for
Hemp	12 to 24 hours	Simmer about 20 to 40 minutes	Most seeds split, white shoot showing	Holding fish on a spot over a carp hookbait
Tiger nuts	24 to 48 hours	20 to 60 minutes (sources vary widely)	Squashes under firm thumb pressure	Selective carp hookbait
Maize	12 to 36 hours	30 to 60 minutes	Some grains split, soft to squash	Cheap, highly visible carp bait
Chickpeas	About 12 hours	About 30 minutes	Soft	Budget bait that takes flavour and colour
Maple peas	Up to about 18 hours	35 to 45 minutes, skimming off the scum	Soft	Carp
Sweetcorn (tinned)	None	None, already cooked	Ready from the tin	Almost everything that swims
Parti-blend	Depends on the product; some need none	Follow the pack	Squash test	Mixed carp spots

Ranges are drawn from Fishing Again, Haith’s, Carpology and Angling Times.

Tares are missing on purpose. We found only one source for their cooking time, so follow your supplier’s instructions.

Tiger nuts are the particle most worth getting right. They’re hard, so the long soak matters most, and they’re banned on many waters. Haith’s own recipe adds a further 24 hours’ standing after a 45 minute boil, which is one supplier’s method rather than a requirement. Our guide to tiger nut fishing for carp covers rigs and feeding.

Hemp and corn have their own pages: preparing and fishing hemp and sweetcorn as bait.

New to particles? Start with tinned corn and ready-prepared hemp, then move on to tigers and maize once you trust your squash test.

Can Unprepared Particles Harm Fish? What We Actually Know

Almost every particle guide warns that dry particles can kill carp. We couldn’t find one that cites a study.

The claim: unsoaked particles keep absorbing water after a fish eats them, swell in the gut and can harm it. Fishing Again says enough can be fatal. Haith’s says maize must be prepared so it doesn’t blow up in a carp’s stomach. It’s widely held angling guidance.

What we could not find is a statement from the Environment Agency, the Angling Trust or Cefas backing it up. That doesn’t make it a myth. It means the warning comes from anglers and bait firms rather than published research.

The practical answer is the same either way. Fisheries enforce prepared-particle rules regardless, and preparing costs you only time. Prepare everything, and never scatter leftover dry bait.

Separately, raw red kidney beans are a food-safety risk for people. The Food Standards Agency warns that raw or undercooked red kidney beans contain a lectin that can be toxic. Oxfordshire County Council’s guidance is to soak them for at least 12 hours, then boil vigorously for at least 10 minutes before simmering. That applies to kidney beans, not to particles in general.

How to Make a Particle Mix

One bucket, four ingredients. A particle mix pairs a small attractor with bigger particles, so fish settle on the spot and still find your hookbait.

Fishing Again gives this example recipe:

60% hemp
20% tiger nuts
10% sweetcorn
10% maize

Combine them and leave the mix in a sealed bucket for at least an hour with an attractant. It’s one writer’s recipe, not a standard, so adjust the ratios to the water.

The rule that matters: prepare each particle separately, to its own soak and cook time, then combine them. Keith Sykes makes this point in Carpology, and the table above shows why. Cook hemp as long as tigers and it turns to mush. Tinned corn goes in last, straight from the tin.

On a water that bans nuts, drop the tigers and raise the maize or chickpeas. Check first whether the fishery treats chickpeas like nuts, because some do.

Go easy on flavour too. John Baker, writing in Carpology, sees little benefit in masking the natural aroma of particles on pressured venues.

A mix suits building a spot for carp or tench over a day or a weekend. On a short session at a small commercial, a few handfuls of hemp and corn will do the same job with far less preparation.

How Much Particle Bait to Feed (and Go Easy on Salt)

You put three kilos in, then sat on a dead spot all afternoon. Overfeeding is one of the easiest ways to waste particle baits, because fish can only eat so much.

Tiger nuts need the most restraint. Fishing Again suggests a handful with the hookbait and a few dozen over a spot. Angling Times suggests one or two on the hair over a small handful of freebies.

Hemp can go in more freely because the seeds are tiny, but start modestly and top up when you see bites or bubbles. You can always add more. You can’t take it back out.

A reliable approach is to build a spot with hemp and a few tigers or maize, then fish a boilie or tiger over the top. Where small fish keep stealing corn, a grain of plastic corn on the hair gets round them.

Additives deserve the same restraint. John Baker has raised concerns in Carpology about how much salt goes into waters, though he says a small amount does no harm. Use salt sparingly, keep oils and flavours light, and follow any bait quantity limits the fishery sets.

Storing Prepared Particles Safely

The bucket you forgot in the garage is now a science experiment. Cooked particles go off, so plan storage before you cook.

Cool prepared particles quickly and keep them in their own liquid. Fishing Again says hemp keeps about 3 to 4 days in the fridge, and John Baker puts cooked particles at up to a week. For anything longer, freeze in session-sized bags. Keith Sykes notes that hemp freezes well and that salted water preserves cooked hemp for a time.

Haith’s warns that extended soaking is a fine line between fermenting and mould. Some anglers ferment tigers on purpose, but if a batch is mouldy or smells foul, bin it.

Cook only what you’ll use in the next few days. Bag and freeze the rest on the day you cook it, while it’s fresh, rather than after it has sat in the bucket.

Fishery Rules on Particles and Tiger Nuts

Two council-run lakes in London take opposite positions on tiger nuts. Croydon Council’s 2026 rules for South Norwood Lake say no tiger nuts. Southwark Council’s rules for the Burgess Park lake say tiger nuts are the only nut bait permitted.

That’s why you read the rules before you cook anything. Common rule types include:

No nuts at all
No tiger nuts
Particles in moderation
Shop-bought prepared particles only, a rule some carp fisheries apply

Do tiger nuts count as nuts? Anglers argue about it on forums whenever a club writes “no nuts” into its rules. Assume tigers are included unless the rules say otherwise, and ask the fishery if in doubt. Chickpeas sometimes get the same treatment, so check them too.

You’ll also need a valid rod licence where one is required. See our rod licence rules.

Rules change, so check the current rules with the council or fishery before you travel. Read the board in the car park, or the fishery’s website, before you mix a bucket.

Frequently asked questions

Do you have to boil particles for fishing?

Conventional advice is to soak and then boil. Soaking is the step that stops particles swelling, and boiling softens them. Tinned sweetcorn and ready-prepared packs skip both. See the preparation section above for the full method and the squash test.

How long do you soak tiger nuts?

Sources give 24 to 48 hours, followed by cooking until a nut squashes under firm thumb pressure. Published boil times range from 20 to 60 minutes. If in doubt, soak and cook longer, never shorter.

Can you use tinned sweetcorn for carp?

Yes. Tinned sweetcorn is already cooked, so give it a rinse and use it straight from the tin. Check the fishery rules first, and if small fish keep taking it, try plastic corn on the hair.

What are the best carp particles in the UK?

Hemp, maize, tiger nuts and sweetcorn are the core four carp particles in the UK, with chickpeas, maple peas and tares as useful extras. Each does a different job, so see the comparison table above rather than picking one winner.

Can you use kidney beans as bait?

Avoid raw red kidney beans. The Food Standards Agency warns that raw or undercooked red kidney beans contain a lectin that can be toxic to people. If you can't be sure they're properly prepared, leave them out of the bait bucket.
