Yes, you can keep nightcrawlers alive in the fridge. This is a smart and common way for storing bait worms like Canadian nightcrawlers to keep them fresh for fishing trips. With the right care, they can last for several weeks, sometimes even a few months. So, how long do nightcrawlers last in this cold spot? It depends on how well you set things up and look after them. The best worm bedding material for this is usually a mix of things like peat moss or shredded paper. This mix works well as Nightcrawler bedding in a worm storage container placed in the fridge.
Keeping keeping fishing worms alive is key for a good day by the water. Worms are living things. They need the right home, food, and care. The fridge offers a way to slow down their life cycle. This makes them last much longer than if you kept them at room temperature.

Why a Fridge Helps Worms
Putting worms in the fridge might sound strange. But it is actually good for them. Wild nightcrawlers live outside. They dig deep when it gets hot or cold. The fridge is like a cool, stable spot for them to rest.
It Slows Them Down
Worms move and grow fast when it’s warm. This uses up their energy quickly. In the fridge, the cold air makes them slow down. Their bodies use less energy. They need less food and create less waste. This helps them live longer in a small space. It’s like putting them into a sleepy mode.
It Keeps Things Clean
Warm places can grow bad things fast. Think mold and bad smells. A cool fridge helps stop this. It slows down mold growth (preventing mold in worm container). It also keeps smells down because the worms are less active. This makes their home cleaner and healthier for them over time.
What You Need
To keep your worms happy in the fridge, you need the right supplies. Think of it like setting up a small house for them.
Picking a Home
You need a good worm storage container. This container should be made of plastic. It should have a lid. The most important part is that the lid needs holes. Worms need to breathe. Small holes poked in the top or sides work well. Do not make the holes too big. You don’t want worms to get out. A container that holds about 1 to 5 pounds of worms is a good size for most people.
- Size: Pick a size based on how many worms you have. A bigger container is usually better. It gives worms more space.
- Material: Plastic bins or old margarine tubs work. Make sure they are clean.
- Ventilation: Air holes are a must! Worms need air.
Choosing Bedding
The stuff you put in the container is called Nightcrawler bedding. This is very important. It’s where the worms live. It gives them shelter and a little bit of food. The best worm bedding material holds moisture well but also lets air get through.
Good bedding choices include:
* Peat Moss: This is often sold in garden stores. Make sure it’s plain peat moss, not the kind with added plant food.
* Coconut Coir: This comes from coconuts. You usually buy it as a dry block. You add water to make it fluffy. It holds water very well.
* Shredded Newspaper: Rip up plain newspaper (no glossy pages or colored ads). This is a cheap option.
* Cardboard: Shredded cardboard works too. Plain brown cardboard is best.
A mix of these can be great. For example, mixing peat moss and shredded newspaper. This helps the bedding hold moisture and stay airy.
Things to Add
You might want to add a little bit of food or other things to the bedding.
* Worm Food: Special worm food can be bought. It’s usually like a cornmeal mix. You only need a tiny bit in the fridge.
* Dirt: Some people add a little clean soil. This can help worms feel more at home. But too much can make the container heavy and pack down the bedding.
Tools for Checking
You will need a few simple tools:
* Spray Bottle: To add moisture for nightcrawlers.
* Hand Trowel or Spoon: To stir the bedding and check on worms.
* Container: The worm storage container itself.
Setting Up the Worm Home
Getting the container ready is the first step to keeping fishing worms alive in the cold. It needs to be done right.
Get the Container Ready
First, clean your plastic container. Use soap and water, then rinse it very well. You don’t want any soap left behind. Soap is bad for worms. Once clean, make the air holes. Use a small drill bit or a hot nail to poke holes. Put holes on the lid and maybe some on the top sides. Aim for many small holes rather than a few big ones. This lets air in but keeps worms from escaping.
Prepare the Bedding
Take your chosen Nightcrawler bedding material. If you use peat moss or coconut coir, it will likely be dry. You need to add water. The bedding should be damp like a wrung-out sponge. Not soaking wet, but not dry and dusty.
- Put the dry bedding in a bucket.
- Slowly add clean water.
- Mix it with your hands.
- Squeeze a handful. If water drips out easily, it’s too wet. Add more dry bedding. If it just feels cool and damp, it’s right.
- If using newspaper or cardboard, shred it first. Then dampen it the same way.
Once the bedding is damp enough, put it into the worm storage container. Fill it about halfway to two-thirds full.
Add the Worms
Now, gently put your nightcrawlers into the container. Spread them out a bit on top of the bedding. They will quickly start to burrow down.
Put the Lid On
Place the lid with holes firmly on the container. The holes are very important. Without them, the worms will not get air and will die.
Fridge Life: The Cold Facts
Once your worm home is set up, it’s time to put it in the fridge. But not just any fridge spot will do.
Finding the Right Temperature
The refrigerator temperature for worms is key. You want it cold, but not freezing. A good range is between 34°F and 40°F (1°C to 4°C). This is the same temperature you keep food at. Most home fridges are set in this range.
- Avoid the Freezer: Freezing will kill your worms.
- Avoid the Crisper: The crisper drawers can sometimes get colder or hold too much moisture. The main shelf is often best.
- Check the Temp: If possible, use a small fridge thermometer to check the spot where you will keep the worm container. Make sure it stays in the right range.
Keeping It Just Right
Moisture for nightcrawlers is very important. The bedding should stay damp. Check it every week or two. Stick your finger in. If it feels dry, spray some clean water on top. Use a spray bottle so you don’t add too much water at once. Don’t stir the bedding just after adding water. Let the water spread on its own.
Food? Not Much Needed
Worms in the fridge are not very active. They eat very little. If you used peat moss or coconut coir, the bedding itself has some small food bits they can eat. If you want to give them extra food, use a tiny amount. A pinch of special worm food or cornmeal once every few weeks is enough. Too much food will just sit there and mold (preventing mold in worm container).
Checking On Your Worms
You should check on your worms regularly. Maybe once a week or every two weeks.
* Open the lid.
* Look inside. Do you see live worms?
* Gently stir the top layer of bedding with a spoon or hand trowel. Look for worms deeper down.
* Check the moisture for nightcrawlers. Does the bedding feel damp?
* Look for any dead worms. Remove them right away.
Cleaning the Home
Over time, the bedding will get used up and dirty with worm waste. You will need to change it. How long do nightcrawlers last in the same bedding? Not forever. Plan to change the bedding every 1-3 months, depending on how many worms you have and how they are doing.
- Prepare fresh, damp
Nightcrawler bedding. - Gently dump the old bedding and worms onto a tray or piece of plastic.
- Pick out the healthy worms.
- Clean the
worm storage containerwell with water. - Put the fresh bedding into the clean container.
- Add the healthy worms.
- Throw away the old bedding.
Dealing With Issues
Even with good care, you might run into problems when keeping fishing worms alive in the fridge.
Dead Worms
It’s normal to have a few worms die sometimes. But if many are dying, something is wrong.
* Too Wet/Dry: Check moisture for nightcrawlers. Is the bedding too wet or too dry? Fix it.
* Wrong Temp: Is the refrigerator temperature for worms correct? Not too cold or warm?
* Bad Air: Are the air holes blocked? Do they have enough air?
* Old Bedding: Is it time to change the Nightcrawler bedding? Old bedding can become toxic.
* Overcrowding: Do you have too many worms in one container? Use a bigger one or split them.
Always remove dead worms right away. They will rot and harm the other worms.
Smells
A healthy worm bin in the fridge should not smell bad. A bad smell means something is wrong.
* Rotting Food: Too much food was added and is going bad. Remove any leftover food.
* Too Wet: Bedding that is too wet can smell bad and lack air. Add some dry bedding material to soak up extra water.
* Dead Worms: Remove any dead worms.
White Stuff
Sometimes you might see white fuzzy stuff in the bedding. This is usually mold. While some mold is okay outside, too much in a closed container can be bad (preventing mold in worm container).
* Too Much Food: Mold often grows on uneaten food. Remove leftover food.
* Too Wet: Mold likes wet places. Check moisture for nightcrawlers. If it’s too wet, add dry bedding.
* Poor Airflow: Make sure the air holes are open and clear.
* Old Bedding: Change the bedding if it’s old and full of waste.
How Long Will They Last?
People often ask, how long do nightcrawlers last when kept in the fridge? With proper care, storing bait worms this way can keep them alive for 1 to 3 months, sometimes even longer. This is much better than leaving them in a warm spot, where they might only last a week or two.
What Affects Their Life Span
Several things change how long your worms will live in the fridge:
* Starting Health: Were the worms healthy when you got them?
* Fridge Temperature: Staying in the right refrigerator temperature for worms range is key.
* Bedding Quality: Good Nightcrawler bedding helps a lot.
* Moisture Level: The right moisture for nightcrawlers keeps them healthy.
* Airflow: Enough air means healthy worms.
* Cleaning: Removing dead worms and old bedding helps.
* How Often You Check: Looking in on them helps you catch problems early.
Signs They Are Healthy
Healthy worms in the fridge look good.
* They are firm, not mushy.
* They move when you touch them.
* They bury themselves in the bedding.
* The bedding smells fresh like earth, not bad.
Special Care for Canadian Nightcrawler Care
Canadian nightcrawlers are a popular type of worm for fishing. They are large and lively. Canadian nightcrawler care in the fridge is similar to other nightcrawlers, but they have a few specific needs.
They Like It Cold
Canadian nightcrawlers really like cooler temperatures. The lower end of the fridge temperature range (around 34-36°F or 1-2°C) is often best for them. They handle the cold very well.
More Room, Please
Canadian nightcrawlers are bigger than some other worms. They need more space per worm. Don’t crowd them. Make sure your worm storage container is big enough for the number of worms you have. Using plenty of good Nightcrawler bedding gives them space to move around and reduces stress.
Keeping fishing worms alive, especially the big ones like Canadians, means giving them space and keeping them cool and clean.
Buying vs. Digging
You can buy nightcrawlers from a store or dig them up yourself. This can affect how you care for them.
Store-Bought Worms
Worms from a bait shop are often already used to living in containers. They might come in their own bedding. You can sometimes keep them in the container they came in for a short time. But moving them to a larger worm storage container with fresh best worm bedding material is usually better for longer storing bait worms. Store worms are often already sorted and healthy.
Worms From Your Yard
Worms you dig up might have other things in the dirt with them (bugs, plant roots). The soil from your yard might not be the best worm bedding material for long-term fridge storage. It can pack down too much. It’s a good idea to put dug worms into fresh, prepared Nightcrawler bedding before putting them in the fridge. Check them closely for any other bugs that hitched a ride.
Quick Tips for Success
Here is a quick list of things to remember for keeping fishing worms alive in your fridge:
- Use a clean
worm storage containerwith air holes. - Choose good
Nightcrawler bedding(peat moss, coir, shredded paper). - Make the bedding damp like a wrung-out sponge.
- Keep the
refrigerator temperature for wormsbetween 34°F and 40°F. - Check
moisture for nightcrawlersoften and spray if dry. - Give very little or no food in the fridge.

Frequently Asked Questions (FAQ)
h4: Can I use regular dirt from my yard as bedding?
Regular dirt can get too packed down. This stops air from reaching the worms. It might also have bad bugs or things in it. It is much better to use materials like peat moss, coconut coir, or shredded newspaper. These materials stay fluffy and let air in. They are the best worm bedding material for a worm storage container in the fridge.
h4: How often do I need to feed the worms in the fridge?
Worms in the fridge are very slow. They eat very little. If you use good Nightcrawler bedding, it has enough food in it for a while. You only need to add a tiny bit of food, like a pinch of cornmeal, maybe once every few weeks or even less often. Too much food will rot and cause problems (preventing mold in worm container).
h4: My worm bedding looks dry. What should I do?
If the bedding feels dry when you check it, use a spray bottle. Lightly spray the top of the bedding with clean water. Don’t soak it. Just make it damp again. The goal is damp like a wrung-out sponge. Proper moisture for nightcrawlers is key to keeping fishing worms alive.
h4: I see some white fuzzy stuff. Is this bad?
White fuzzy stuff is usually mold. A little bit is okay, but a lot can be bad (preventing mold in worm container). Mold often grows when the bedding is too wet or there is too much uneaten food. Remove any extra food. If it’s too wet, add some dry bedding. Make sure the container has enough air holes. Changing the bedding might be needed if the problem is bad.
h4: How can I tell if the fridge temperature is right?
The refrigerator temperature for worms should be between 34°F and 40°F (1°C to 4°C). Most fridges are set in this range for food. You can use a cheap fridge thermometer to check the spot where you keep the worm container. This helps make sure it stays at the right cold level for storing bait worms.
h4: My worms look thin and not lively. What’s wrong?
This could be a few things. Maybe the bedding is old and needs changing. Maybe they are too warm (check the refrigerator temperature for worms). Maybe the bedding is too dry (check moisture for nightcrawlers). Or maybe they need more space (get a bigger worm storage container). Good Canadian nightcrawler care and general keeping fishing worms alive means checking these things.
h4: Can I use the same container for different kinds of worms?
It is generally best to keep different types of worms in separate containers. Different worms might have slightly different needs for Nightcrawler bedding or space. Also, it prevents mixing species.
h4: How long can worms stay in the container they came in from the store?
The small containers from the store are usually okay for a few days to a week if kept cool. But for longer storing bait worms, it’s much better to move them to a larger worm storage container with proper best worm bedding material. This gives them more space, fresh bedding, and better airflow. This helps answer how long do nightcrawlers last in poor vs. good conditions.
h4: What if the bedding smells sour?
A sour smell often means the bedding is too wet, has too much food, or needs changing. It’s a sign that air is not getting through well, and bad things are growing. Remove dead worms, remove any old food, and add dry bedding if it’s too wet. If the bedding is old, change it completely. This is part of preventing mold in worm container and bad smells.
h4: Do Canadian nightcrawlers need special bedding?
Canadian nightcrawler care often involves using bedding they prefer. Peat moss is a very popular and effective Nightcrawler bedding for them. Mixing it with some shredded newspaper or cardboard also works well. The main thing is that the best worm bedding material for them is cool, moist, and airy.
h4: Can I keep the worm container in an unused fridge in the garage?
Yes, this can work well for storing bait worms. An extra fridge just for worms keeps them separate from your food. Just make sure the garage fridge keeps a steady refrigerator temperature for worms between 34°F and 40°F, no matter how hot or cold the garage gets. Some older fridges might not hold a steady temperature well.
h4: What is the number one thing to remember for keeping them alive?
The most important things are keeping them cool (right refrigerator temperature for worms) and making sure their Nightcrawler bedding is damp like a sponge (moisture for nightcrawlers) and can breathe (air holes in the worm storage container). If you get those things right, your worms have a great chance of lasting a long time. This is central to keeping fishing worms alive.
