Fishing with worms is the oldest and most reliable way to catch freshwater fish in America. A live nightcrawler wiggling on a hook catches bluegill, bass, catfish, trout, perch, walleye and carp, from farm ponds in Georgia to trout streams in Pennsylvania. It's cheap, it works in almost any water, and it's how most of us caught our first fish.
This guide covers which worms to buy, how to hook them, the four rigs worth knowing and when to fish them. If you're just starting out, our how to fish guide covers gear, knots and the basics first.
Nightcrawlers vs red wigglers
Not all worms are the same. The two you'll find at most bait shops and gas stations:
| Worm |
Size |
Best for |
Notes |
| Nightcrawler |
4–8 in, thick |
Bass, catfish, walleye, trout, carp |
Strong scent, lots of action. Use whole or cut in pieces. |
| Red wiggler |
1–3 in, thin |
Bluegill, sunfish, perch, trout in small streams |
Very lively; fits small hooks; great for kids. |
| Garden / leaf worm |
2–4 in |
Panfish, creek fish |
Free if you dig them; check local rules on transporting bait. |
| Plastic worm |
4–10 in |
Bass |
Not live bait, but rigged the same way on Texas and Carolina rigs. |
Keep live worms cool (around 40–50°F / 4–10°C), out of the sun, in damp bedding. A cooler in the truck beats the dashboard every time. Dead, mushy worms catch far fewer fish.
How to hook a worm
How you hook the worm depends on the fish and the hook size.
- Threaded (panfish): push a small hook (size 6–10) in one end and thread a short piece of worm up the shank, leaving a tail to wiggle. Bluegill can't steal it as easily.
- Wacky / middle hook: hook a nightcrawler once or twice through the middle so both ends dangle. Great natural action for bass and trout.
- Gob (catfish, carp): loop a whole crawler or two several times onto a size 1–2/0 hook. More scent, more bulk.
- Nose hooked: one pass through the thick collar end, used for drifting in current and on crawler harnesses so the worm trails straight.
Two tips: leave the hook point exposed (or barely covered) so it can set, and use a hook that matches the fish's mouth, not the worm.
Four worm rigs every angler should know
1. Bobber rig
The classic. A float, a split shot 6–12 in above the hook, and a piece of worm set 1–4 ft deep. Perfect for bluegill and crappie near weeds and docks. When the bobber dives, reel up slack and lift. Our bluegill fishing tips go deeper on depth and spots.
2. Bottom rig (slip sinker)
A sliding egg or walking sinker on the main line, a bead and a swivel, then 12–24 in of leader to the hook. The fish can pick up the bait without feeling the weight. This is the go-to for catfish and carp off a bank. For other catfish options, see best catfish bait.
3. Carolina rig
Similar to the bottom rig but with a heavier sinker and a longer leader (2–4 ft), dragged slowly across flats and points. Works with a live crawler for walleye and bass in summer.
4. Drop shot
The hook is tied above the weight, with 6–18 in of line below it. The worm floats off the bottom where fish see it. Excellent for finicky fish in clear lakes, for perch, and for smallmouth on rocky bottoms.
Bonus: drifting in streams
For trout and river smallmouth, cast upstream with a light split shot and let a nose-hooked worm tumble naturally with the current. Many trout waters restrict live bait, so check rules before you go. More in best bait for trout.
What you can catch with worms
- Bluegill and sunfish: small pieces on a size 8–10 hook under a bobber. Nearly foolproof from late spring through summer.
- Largemouth and smallmouth bass: a whole nightcrawler, wacky or on a Carolina rig.
- Catfish: gobs of crawlers on the bottom, especially in warm, stained water.
- Trout: drifted worms after rain, when runoff washes real worms into creeks.
- Yellow perch: small pieces on a drop shot or bottom rig in the Great Lakes and northern lakes.
- Walleye: crawler harness behind a bottom bouncer in summer.
- Carp and drum: on the bottom near muddy flats.
Regional notes for US anglers
- South (Texas to the Carolinas): worms catch bream and catfish nearly year-round in ponds and reservoirs. In summer heat (water above 85°F / 29°C), fish early, late, or deeper.
- Midwest: crawlers and slip bobbers on farm ponds and natural lakes in Wisconsin, Minnesota and Michigan are a summer staple.
- Great Lakes: perch anglers on Lake Erie and Lake Michigan often fish minnows, but crawler pieces work well when perch are on the bottom.
- Appalachia: drifted worms after a spring rain are a classic for stocked trout in Virginia, Tennessee and North Carolina, on waters where bait is allowed.
- Rockies and Pacific NW: many trout streams are artificial-only or catch-and-release. Lakes and ponds are usually where worms are allowed.
Some states restrict live bait, ban moving bait between waters, or require it be bought locally. Check your state's fishing regulations before using worms.
When to fish worms: timing and solunar periods
Worms work all day, but fish feed harder at certain times:
- Dawn and dusk: the most reliable windows in summer, when the water is cooler and light is low.
- After rain: runoff washes worms into lakes and creeks, and fish know it. A rising, muddy creek can be a fantastic worm bite. See fishing in the rain.
- Stable or falling pressure: fish often feed actively ahead of a front and slow down on bright, high-pressure days after it.
- Solunar periods: the major (moon overhead or underfoot) and minor (moonrise and moonset) windows are when many anglers see a spike in bites. When one overlaps sunrise or sunset, that's the hour to be on the water.
- Moon phase: days around the new and full moon are traditionally rated highest. See best moon phase for fishing.
If you fish with kids, plan the trip around one of these windows. A busy bobber keeps them interested.
Using the Solunar app
Solunar: Hunt & Fish calculates the day's major and minor periods, sunrise, sunset, moonrise, moonset and moon phase from your location, all offline. Everything sits on a 24-hour dial with a 1–4 star day rating, so you can see at a glance whether this evening's window lines up with dusk at your pond.
FAQ
Are nightcrawlers or red wigglers better for fishing?
Nightcrawlers are better for bigger fish like bass, catfish and walleye. Red wigglers are smaller and very lively, ideal for bluegill, perch and small-stream trout.
How deep should I set a bobber with a worm?
Start 2–3 ft deep for bluegill and adjust until you get bites. Near weeds or docks, set it just above the cover.
Can you use worms for trout?
Yes, where live bait is legal. Drift a small piece naturally in the current. Many trout streams are artificial-only, so check your state regulations.
What time of day is best for fishing with worms?
Early morning and evening, especially when a solunar period lines up with them. After a rain is another prime time.
