The worm is arguably the most natural and versatile bait in UK coarse fishing. Before pellets, boilies, and commercially manufactured groundbait, British anglers fished with worms – and the worm still outperforms everything else in certain situations. For perch, chub, barbel, tench, and bream, there are days when a worm on the hook produces fish when nothing else works.
This guide covers the main types of worm used in UK coarse fishing, how to use each, which species respond best, and the practical business of sourcing and storing worms.

The Main Worm Types
Lobworm (Lumbricus terrestris)
The largest UK earthworm, reaching 10-30cm when stretched. A dark red-brown on the top surface with a paler, more yellowish underside. The lobworm is unmistakeable by its size and the flattened paddle-shaped tail end.
Fishing uses: – Big perch: A large lobworm fished under a float in a river or canal is one of the most reliable big perch presentations in UK coarse fishing. – Chub: Freelined lobworm rolled to likely chub lies in rivers produces dramatic results in summer and autumn. – Barbel: A lobworm or worm section ledgered in rivers can be very effective, particularly in flood conditions when the river runs coloured. – Bream: A lobworm tail section on a hook over a bed of groundbait picks out better bream from a mixed roach and bream swim. – Tench: A bunch of lobworm tails on a size 10 hook is an excellent tench bait, particularly early in the season. – Pike: A large, fresh lobworm on a small treble hook is a semi-specialist bait for river pike and perch, imitating the food items that large predators naturally encounter. – Eel: Worms are the primary eel bait. A bunch of lobworm tails on a size 6 hook fished on the bottom at night is classic eel fishing.
How to hook a lobworm: – Full worm: Pass the hook through the head section (the smooth, pointed end) once, leaving the tail to wiggle – Tail section: Cut the bottom third and use as a hookbait, giving maximum scent and juiciness without the bulk of the full worm – Head section: The more robust part; good for casting distance
Redworm (Eisenia fetida / E. andrei)
The small, brightly red earthworm found in compost heaps and leaf litter. Typically 5-10cm, much smaller and more intensely coloured than lobworm. Redworms are lively and stay hooked well.
Fishing uses: – Tench: Arguably the best tench bait in the UK. A bunch of 2-3 redworms on a size 10 hook is the classic lift method tench presentation. – Perch: Redworm is excellent for perch, particularly in rivers. Small redworms on a size 16 hook catch perch that may ignore larger baits. – Roach: A single redworm on a size 14 hook can produce quality roach when maggots only produce small fish. River roach respond particularly well to a worm on cooler days. – Bream: Redworm is underused as a bream bait. A tail section on a size 12-14 hook fished over groundbait can select better bream. – Match fishing: Redworm on a size 16-18 hook is a legitimate match bait for river fishing, particularly in autumn and early winter when other baits are less productive.
How to hook a redworm: Thread the hook through the worm multiple times if using the whole worm, or nip off and use a section. A bunch of 2-3 redworms on a size 10 hook for tench; a single redworm on a size 14-16 for roach and perch.
Dendrobaena Worm (Eisenia hortensis)
A medium-sized, robust worm (10-15cm) widely sold in fishing tackle shops. Dendrobaena worms are tougher than redworms and easier to handle in cold or wet conditions – they do not go limp as quickly when impaled on a hook.
Fishing uses: Essentially interchangeable with redworm in many applications. More robust for casting. Good for tench, perch, barbel, and chub. The dendrobaena is the commercially sold “fishing worm” available in most UK tackle shops.
How to hook a dendrobaena: Identical approaches to redworm. A single dendrobaena on a size 12 hook covers most applications. A bunch on a size 8-10 for barbel.
Brandling Worm
A smaller worm found in manure and very rotten compost, identifiable by its distinct yellow-orange rings along a darker body. Strong smell when cut. Used as a tench bait and river roach bait historically, though dendrobaena and redworms have largely replaced it in modern fishing.
Tactics by Species
Perch (with worm)
Perch are strongly attracted to worm at all sizes. The larger the perch, the larger the worm presentation is appropriate.
River perch: A lobworm or large dendrobaena under a running float (or light ledger) in a river gives the bait time to move naturally. Present it near snags, bridge supports, or the inside of bends where perch hold. Let the worm settle on the bottom and be patient – large perch examine food carefully before taking.
Still water perch: A worm fished under a waggler float at depth in a swim known to hold perch is effective. On commercial fisheries with large perch populations, a large lobworm on a drop-shot rig worked slowly along the bottom can be deadly.
Chub (with worm)
Large, fat lobworms freelined to visible chub lies in rivers are one of the most exciting ways to catch chub. The worm is cast just upstream of a likely hold (under a fallen tree, below a weir, in a deep undercut bank) and allowed to drift naturally to the fish. Chub take a lobworm decisively – the bite is usually visible and the take forceful.
In summer and early autumn, freelining a whole lobworm with no weight on the line gives the most natural presentation. In cooler conditions when chub are less active, a ledgered worm in a deep pool is more reliable.
Barbel (with worm)
Worm is an underused barbel bait – most anglers default to meat, boilies, and pellets. But a fresh lobworm or a bunch of dendrobaena worms on a size 6-8 hook ledgered on the riverbed in a known barbel swim can produce excellent results, particularly in flood conditions when coloured water gives a scent advantage.
A useful combination: a PVA mesh bag of chopped worm and hemp seed placed at the hook before casting gives an immediate scent concentration around the hookbait.
Tench (with worm)
The redworm is the single most reliable tench bait for UK stillwaters. A bunch of 2-3 redworms on a size 10 hook, fished lift-method or on a light ledger, fished over a bed of groundbait and loose redworm pieces at dawn, produces consistent tench in late spring and summer.
Bream (with worm)
Bream respond well to worm, particularly lobworm tail sections. On rivers and still waters where bream share swims with smaller roach, a worm section on a size 10-12 hook tends to select larger fish. The worm is large enough to deter small roach but attractive to bream.
Eel (with worm)
Worm is the primary eel bait. A bunch of lobworm tails on a size 6 hook, ledgered on the bottom in a muddy or silty section of river or lake at night from June to August, is the standard approach. Eels are nocturnal summer feeders and worm is the most natural food item in their diet.
Sourcing and Storing Worms
Where to source worms
Tackle shops: Dendrobaena worms and sometimes redworms are sold in virtually all UK fishing tackle shops, either in tubs or bags. Lobworms are less commonly stocked (they are harder to breed commercially) but some specialist shops carry them.
Digging: Lobworms are found in garden soil and lawns, particularly in the evening after rain or at night with a torch. After heavy overnight rain, they come to the surface and can be collected from grass. Redworms are found in compost heaps and leaf litter.
Worm farms: Several UK suppliers sell fishing worms by mail order in bulk – useful if you fish regularly and want a consistent supply.
Storing worms
Lobworms: Store in damp newspaper or moist soil in a cool, dark container (a bait box or bucket with ventilation holes). Do not let them dry out or overheat. Keep below 15°C – a garage or shed is ideal. Lobworms can be kept for weeks in good conditions and can be “scoured” (kept in a damp newspaper for 24-48 hours to clear their gut) to make them firmer for use.
Redworms and dendrobaena: Keep in the container from the tackle shop with damp compost. Store cool. Check weekly and remove any dead worms. A healthy worm tub will last several weeks.
Preparing worms
Chopped worm: Cut worms into small sections (1-2cm) and mix into groundbait as a loose feed or attractor. Chopped worm releases juice and blood that fish find extremely attractive, particularly in cold or coloured water.
Worm cocktail: A widely used approach is “worm and caster cocktail” – a small redworm on the hook with a caster trapped on top, or half a redworm paired with a single maggot. The combination bait gives multiple colour and scent signals.
Frequently Asked Questions
Why use a worm when I can use maggots?
Worms have distinct advantages in several situations. In cold water (below 8°C), worms often outperform maggots because their stronger scent is more detectable in cold, slow-moving water. For larger specimens (big perch, chub, tench), a worm presents a more substantial, naturally occurring food item than a maggot cluster. In coloured river water, the worm’s movement and scent attract fish that may not locate a static maggot.
Can I use worm on a pole or do I need a rod?
Worms work well on a pole with appropriate tackle. A size 14-16 hook on a 1-2lb hooklink with a 0.2-0.4g float is a standard pole worm rig for river roach and perch. Adjust hook size to the worm size – a single dendrobaena on a size 14 is a neat presentation, a bunch of redworms on a size 10 is larger.
Do barbel eat worms naturally?
Yes. Worms are a natural barbel food item – lobworms and earthworms wash into rivers during rain, and barbel have evolved to exploit them. In flood conditions, quantities of worms enter the river from flooded fields and banks, and barbel feed aggressively on them. Worm bait in coloured flood water is particularly effective for this reason.
What is the difference between a redworm and a brandling?
A redworm (Eisenia fetida) is a compost worm with a very deep red colour and no distinct rings. A brandling has alternating dark and pale rings along a more reddish-brown body. Both are found in compost and manure, and both are effective fishing baits. The distinction matters less than many anglers think – the key property is the intense red colour and strong scent both share.
Is it legal to use worms as fishing bait?
Yes, worms are a legal bait in all UK coarse fishing. There are no restrictions on using earthworms as freshwater coarse bait. In some game fisheries (trout and salmon rivers), worm fishing may be restricted by the specific rules of the fishery or club – fly-only beats do not permit worm – but for coarse fishing there is no restriction.
