How to Raise Earthworms for Fishing: Pro Tips for the Ultimate Bait

Let’s be real—if you’re a fisherman (or woman), you know the struggle of showing up to the lake with a fancy tackle box full of lures, only to watch every other angler haul in fish with a plain old earthworm. There’s a reason they’re called the “universal bait”—they work for just about every freshwater fish out there. But here’s the thing: buying worms from the bait shop every time gets expensive, and half the time they’re either dead, mushy, or not the right size for the fish you’re targeting. That’s why I decided to start raising my own earthworms at home—and let me tell you, it’s been a game-changer. No more last-minute runs to the store, no more wasting money on subpar bait, and I get to customize my worm setup exactly how I want it. If you’re ready to take your fishing game to the next level (and save some cash while you’re at it), keep reading. I’m spilling all my best tips for raising healthy, lively earthworms that’ll have the fish practically jumping into your net.

Why Earthworms Are the Ultimate Fishing Bait (No, Seriously)

Before we dive into the how-to, let’s talk about the why. Earthworms aren’t just “good enough”—they’re the gold standard for a reason. First off, they’re natural. Fish have been chowing down on worms for millions of years, so they don’t see them as a threat. Unlike some flashy lures that might scare skittish fish, a wiggling worm looks like a easy meal. Second, they’re versatile. Want to catch bass? Worm works. Crappie? Yep. Trout? Absolutely. Even catfish (the scavengers of the water) can’t resist a juicy worm. And let’s not forget about the scent. Worms have that earthy, fish-attracting smell that lingers in the water, drawing fish from far and wide. I once caught three bass in 10 minutes with a single red worm—try doing that with a plastic lure!

Red Worms: The Rockstars of Fishing Worms

Not all earthworms are created equal, and if you’re serious about fishing, you need to know about red worms (also called red wigglers, though technically they’re a different species—don’t @ me, I’m not a worm scientist). These little guys are the crème de la crème for a few key reasons:

• Size: They’re small (usually 2-38 mm long) which makes them perfect for panfish, trout, and even small bass. No more cutting big worms into pieces (gross).
• Durability: Red worms are tough. They stay on the hook better than other worms, so you don’t have to re-bait every time a fish nibbles. I’ve had red worms stay on my hook through three casts before a bass finally took it.
• Survivability: They can handle extreme temps. Summer heat? No problem. Winter cold? They slow down but don’t die. I keep my worm bin in my garage, and even when it’s 90°F outside, my red worms are still wiggling.
• Smell: Their scent is stronger than other worms, which means more fish are drawn to your bait. I once had a friend use a nightcrawler (a big earthworm) and I used a red worm—same spot, same time. I caught 5 fish, he caught 1. Coincidence? I think not.

Setting Up Your Earthworm Farm: The Easy Way

Okay, so you’re sold on red worms. Now how do you start raising them? First, let’s get one thing straight: you don’t need a fancy setup. I started with a $10 ceramic pot from Walmart, and now I have a bin that produces enough worms for me and three of my fishing buddies. Here’s what you need:

Step 1: Choose Your Container

You can use a plastic bin, a wooden box, or even a old ceramic pot (that’s what I used first). The key things are:

• Height: At least 50 cm (2 inches) tall—worms need room to burrow.
• Width: 40 cm (16 inches) wide is perfect for a small home setup.
• Drainage: Drill 1 cm (0.5 inch) holes in the bottom—worms hate soggy soil. I forgot to drill holes my first time, and half my worms drowned. Oops.
• Lid: A loose-fitting lid (I use a wooden one) to keep out light and pests but let in air. Worms are blind, but they hate light—if your bin is in a sunny spot, they’ll try to escape.

Step 2: Prepare the Bedding (AKA Worm Home)

Worms don’t live in dirt—they live in bedding. Dirt is too dense, and it doesn’t have the nutrients they need. Here’s how to make perfect bedding:

1. Get 3-8 kg (6-18 lbs) of coconut coir or peat moss (coconut coir is better—it’s more sustainable and holds moisture better). Avoid garden soil—it has pesticides and other stuff that can kill worms.
2. Add water until the bedding is damp, like a wrung-out sponge. If it’s too wet, squeeze it out. If it’s too dry, add a little more water. I once made the mistake of making it too wet—my bin smelled like rotten eggs, and my worms started trying to climb out. Gross.
3. Let the bedding sit for 2-3 days to “ferment” a little. This helps the bedding break down and become more hospitable for worms.

Step 3: Add Your Worm “Starters”

You can’t just go dig up worms from your garden—garden worms are nightcrawlers, and they’re not as good for fishing (plus, they burrow deep, so they’re hard to keep in a bin). You need to buy red worm starters (usually 50-1000 worms) from a bait shop or online. Here’s how to add them:

• Spread the worms on top of the bedding. Don’t dig them in—they’ll burrow down on their own.
• Add a thin layer of food (more on that later) on top to give them something to eat right away.
• Put the lid on and leave them alone for 2-3 days. They need time to adjust to their new home. I once checked on mine every hour the first day, and they were all huddled in a corner—stressful for worms, apparently.

Feeding Your Worms: What They Love (and What They Hate)

Worms are easy to feed, but you have to know what they like. Feed them the wrong stuff, and you’ll have a smelly bin, dead worms, or a worm escape. Trust me—been there, done that.

What Worms Love to Eat

Worms are decomposers, so they eat organic matter that’s starting to break down. Here’s a list of their favorite foods:

• Fruit and veggie scraps: Apple cores, banana peels, carrot tops, cucumber ends—basically anything you’d throw in the compost bin. I save my fruit scraps in a bag in the fridge, then add them to the bin every few days.
• Grains: Cooked rice, oatmeal, cornmeal—just don’t add too much, or it’ll get moldy.
• Tea bags and coffee grounds: Worms go crazy for these! I add used tea bags (remove the string and tag) and coffee grounds from my morning coffee. Just make sure they’re cool—hot stuff will kill worms.
• Eggshells: Crushed eggshells are great for adding calcium to the bedding. I bake mine in the oven for 10 minutes to dry them out, then crush them into a powder. Worms need calcium to make their skin strong.

What Worms HATE (Avoid These at All Costs)

Some foods are toxic to worms, so stay far away from these:

• Salty foods: Chips, pretzels, canned food—worms can’t handle salt. I once accidentally added a little bit of potato chip crumbs, and half my worms died. RIP little guys.
• Oily foods: Grease, butter, fried food—this clogs their pores and kills them.
• Spicy foods: Hot peppers, garlic, onions—worms have sensitive skin, and spicy stuff burns them. Imagine pouring hot sauce on your skin—yeah, that’s what it’s like for them.
• Citrus: Oranges, lemons, limes—too acidic. Worms like slightly acidic bedding, but citrus is way too much.
• Meat and dairy: These rot fast and smell terrible. I once added a little bit of leftover chicken, and my bin smelled like a dead animal. My roommate made me move it to the garage—oops.

Feeding Tips for Healthy Worms

Now that you know what to feed (and what not to feed), here are some pro tips to keep your worms happy:

• Feed once every 1-2 days: Don’t overfeed! If you add too much food, it’ll rot, smell, and kill your worms. I usually add a handful of scraps every other day—just enough so they eat it all in a day or two.
• Bury the food: Don’t leave food on top of the bedding—bury it 2-33 mm (1-1.5 inches) deep. This keeps pests out and makes it easier for worms to find the food. I use a small trowel to dig a hole, add the food, then cover it back up.
• Rotate feeding spots: Don’t feed in the same spot every time. Rotate around the bin so the food is spread out. This prevents mold and keeps all the worms well-fed.
• Adjust for temperature: If it’s hot (above 30°C / 86°F), feed less—worms slow down their eating when it’s warm. If it’s cold (below 15°C / 59°F), feed even less—they almost stop eating when it’s cold. I once fed my worms too much in the summer, and the bedding got moldy. Bad move.

Maintaining Your Worm Bin: Keep Them Happy and Healthy

Worms are low-maintenance, but they do need a little TLC to stay healthy. Here’s what you need to do:

Check the Moisture Level

Worms need damp bedding—too dry, and they’ll die; too wet, and they’ll drown. Here’s how to check:

• Stick your finger 22 mm (1 inch) into the bedding. It should feel damp, like a wrung-out sponge.
• If it’s too dry: Add a little water (use a spray bottle to avoid overwatering) and mix it in. I once forgot to water my bin for a week, and the bedding was dry as a bone. My worms were all huddled in a ball—scared the crap out of me. I sprayed them with water, and they perked up after a few hours.
• If it’s too wet: Add more dry bedding (coconut coir or peat moss) and mix it in. You can also drill a few more drainage holes if the container doesn’t have enough.

Keep the Temperature Right

Worms are happiest between 15°C (59°F) and 30°C (86°F). If it’s too hot or too cold, they’ll slow down or die. Here’s how to keep the temp right:

• Keep the bin in a shaded spot: Don’t put it in direct sunlight—sunlight will heat up the bedding and kill worms. I keep mine in my garage, which is shaded and stays at a consistent temp.
• Cool it down in summer: If it’s hot outside, put a frozen water bottle in the bin (wrap it in a towel first—don’t put it directly on the worms). I do this every few days in the summer, and it keeps the temp down.
• Warm it up in winter: If it’s cold, put the bin in a warmer spot (like a basement or closet). You can also add a little extra bedding to insulate the worms. I once left my bin in the garage in the winter, and the temp dropped to 10°C (50°F). My worms slowed down, but they didn’t die—thank goodness.

Keep Pests Away

Pests like ants, mice, and fruit flies love worm bins. Here’s how to keep them out:

• Keep the lid on tight: A loose-fitting lid keeps out light and pests. I use a wooden lid with a small gap for air—ants can’t get in, but air can.
• Put the bin on legs: If you put the bin on a table or shelf, mice can’t climb up to it. I have my bin on a small shelf in the garage, and I haven’t seen a mouse near it.
• Avoid overfeeding: Overfeeding attracts fruit flies and ants. If you see fruit flies, add a little dry bedding to soak up the moisture, and feed less for a few days.

Harvesting Your Worms: How to Get Them Ready for Fishing

Okay, so your worms are happy and healthy—now how do you get them out of the bin for fishing? Here are the easiest ways:

Method 1: The “Dump and Sort” Method

This is the easiest way, but it’s a little messy. Here’s how to do it:

1. Take the lid off the bin and dump the bedding and worms onto a tarp or old sheet (I use an old bed sheet from my college days).
2. Spread the bedding out into a thin layer. Worms will start to burrow down into the bedding, but they’ll come up to the top if you shine a light on them (worms hate light).
3. Use a small trowel or your hands (wear gloves if you’re grossed out) to pick out the worms. Put them in a container with a little damp bedding.
4. When you’re done, put the bedding back into the bin and add a little fresh food. Your worms will be back to normal in a day or two.

Method 2: The “Bait Bag” Method

This is a cleaner way, and it’s perfect if you only need a few worms. Here’s how to do it:

1. Take a small mesh bag (like a produce bag from the grocery store) and put a little piece of food (like a banana peel or apple core) in it.
2. Bury the bag 22-33 mm (1-1.5 inches) deep in the bedding. Make sure the bag is closed tight.
3. Leave the bag in the bin for 2-3 days. Worms will crawl into the bag to eat the food.
4. Take the bag out of the bin and shake it gently. The worms will be in the bag, and you can put them in your fishing container. Easy peasy!

Storing Worms for Fishing Trips

Once you have your worms, you need to store them properly so they stay alive until you get to the lake. Here’s how:

• Use a container with holes: A plastic bottle with holes drilled in the top (like a soda bottle) or a mesh bag works great. Don’t use a sealed container—worms need air.
• Add a little damp bedding: Put a thin layer of damp coconut coir or peat moss in the container. This keeps the worms moist.
• Keep them cool: Worms stay alive longer if they’re cool. I put my worm container in the fridge (yes, the fridge!) before a fishing trip. Just don’t put them in the freezer—obviously. I once forgot and put them in the freezer, and they turned into popsicles. RIP.
• Don’t overcrowd them: If you put too many worms in a small container, they’ll suffocate. I usually put 2-33 worms in a small soda bottle.

My Personal Worm-Raising Mistakes (So You Don’t Have To)

Let’s be honest—raising worms isn’t perfect. I’ve made my fair share of mistakes, and I want to share them with you so you don’t make the same ones:

• Mistake 1: Using garden soil instead of bedding. I thought dirt was dirt, but garden soil has pesticides and is too dense. My first batch of worms died in a week. Oops.
• Mistake 2: Overfeeding. I once added a huge pile of fruit scraps, and the bedding got moldy and smelled terrible. My roommate made me move the bin to the garage. Lesson learned: less is more.
• Mistake 3: Forgetting to water. I went on a fishing trip for a week and forgot to water my bin. The bedding was dry as a bone, and my worms were all huddled in a ball. I sprayed them with water, and they perked up, but it was a close call.
• Mistake 4: Putting the bin in direct sunlight. I thought the garage was too dark, so I moved the bin to the porch. Big mistake—sunlight heated up the bedding to 35°C (95°F), and half my worms died. Now I keep it in the garage, even though it’s dark.

So there you have it—my complete guide to raising earthworms for fishing. It’s not hard, it’s not expensive, and it’s totally worth it. I now have a constant supply of healthy, lively worms, and I save hundreds of dollars a year on bait. Plus, there’s something satisfying about catching a fish with a worm you raised yourself. It’s like a little victory—you vs. the fish, and you have the perfect weapon.

Last month, I took my son fishing, and we used some of my home-raised red worms. He caught his first bass—1.2 kg (2.5 lbs)! He was so excited, and I was too. We took a picture, and he still talks about it. That’s the magic of worm raising— it’s not just about saving money or catching fish. It’s about making memories, having fun, and being self-sufficient.

If you’re ready to start raising your own worms, go for it! Start small— a $10 pot, 500 red worms, and some fruit scraps. You’ll be surprised at how easy it is, and how much fun it is. And if you make a mistake? No big deal— I’ve made plenty. Just keep trying, and you’ll get the hang of it.

Now go get those worms, and go catch some fish! Let me know how it goes— I’d love to hear your worm-raising stories.
