Composting Worms

If you are looking for healthy, vigorous composting worms (Red Worms and European Nightcrawlers) and unparalleled customer care, you will definitely be in good hands with Red Worm Composting.

Vermicomposting is my major passion in life, and I’ve made it my mission to get as many others involved (and excited) as possible. It only makes sense then that I would want to see people get started with the best worms and guidance.

Don’t just take my word for it though – be sure to have a look at our growing list of testimonials, and spend some time looking around the site in general. I’m confident you will find plenty of evidence demonstrating my level of dedication and integrity.

BEFORE YOU ORDER1) Please be aware, worms ship only ONCE per week (usually on Mondays) – the order deadline for a given shipping week is the Friday prior (so please make sure your order is in by Friday at 6 pm EST if you want the worms the next week). Sometimes, early-Saturday orders are included – but this is not guaranteed.

2) If you DO place an order, PLEASE ensure that we have your current USPS mailing address – the worms are sent via USPS Priority mail. Also make sure that the email address associated with the order is current, and one that you check frequently, since that is where your order confirmation (and updates etc) will be sent. If you receive your Compost Guy receipt you can see what address the worms will be shipped to.

3) Make sure you have read the “fine print” and “additional info” sections before ordering, so you are familiar with our important policies and know what to expect in general

The Worms

Red Worms (Eisenia fetida/andrei) – a.k.a: Red Wigglers, Brandling Worms, Manure Worms, Trout Worms, Tiger Worms

Buy Red Worms

These are the best known and most widely used composting worm. In terms of versatility, no other species can come close to the overall vermicomposting abilities of this worm.

Red Worms can tolerate a wide range of temperatures, can process organic waste materials very quickly, and will increase in numbers at a rapid rate if their primary requirements are met.

This is definitely a species better known for composting applications than as a bait worm, given its smaller size, but they can certainly be used successfully for fishing, and are well-known for their vigorous wiggling action. Red Worms can also be used as an excellent live food for fish, amphibians, reptiles and birds. They are very easy to raise and offer a great source of protein, along with other valuable nutrients.



1 lb Red Worms (U.S. shipping inc) = $54 USD

*** Worms are sent out early each week – please have your order in by Friday at 6 pm EST if you want the worms the next week (but please also keep in mind that sometimes early-Saturday orders get included). ***

*** Worm Species “Purity” – Important *** – Some customers wonder if they will receive 100% pure Eisenia fetida. Unfortunately, unless the worms are raised under laboratory (or at least very isolated) conditions this is virtually impossible to guarantee. There are two very closely related species (Eisenia fetida and Eisenia andrei) that occur in mixed populations a lot of the time. Blue Worms (Perionyx excavatus) are a very well-known “invader” of Red Worm beds in worm farming operations, so you can end up with some of them at times as well. The good news is that all these worms (and various others) are great for composting, so don’t panic if it seems like you have some different kinds of worms. If you have any questions/concerns, don’t hesitate to let me know at any point along the way.

European Nightcrawlers (Eisenia hortensis) – a.k.a: Belgian Nightcrawlers, Euros, ENCs

European Nightcrawler

The European Nightcrawler is a larger cousin of the Red Worm, and while certainly useful as a composting worm, is widely known for its potential as a bait worm.

Not only is it the perfect size – larger than a Red Worm, and smaller than a Canadian Nightcrawler (Lumbricus terrestris) – but it is also very durable, and tolerant of a wide range of conditions. I’ve read that these worms can even be used successfully in brackish waters and for ice fishing!

Unlike Canadian Nightcrawlers (also known as ‘Dew Worms’), this species also does not need to be refrigerated during storage – although doing so may help to increase their shelf life even longer since it slows down their metabolism.

Research seems to indicate that European Nightcrawlers aren’t as prolific in the breeding department as Red Worms, nor are they as effective when it comes to processing organic wastes. Many worm farmers disagree – some indeed consider the Euro to be the “perfect” worm.



1 lb ENCs (U.S. shipping inc) = $51

*** Worms are sent out early each week – please have your order in by Friday at 6 pm EST if you want the worms the next week (but please also keep in mind that sometimes early-Saturday orders get included). ***

The Guarantee

Customer satisfaction is extremely important to me. A major goal of mine is to get as many people excited about (and involved in) vermicomposting as possible. This obviously won’t happen if people get poor products and terrible customer service.

Needless to say, you are 100% guaranteed to receive living worms – that’s a no brainer! Just be sure to check out the fine print for the conditions that apply there (customers do take some responsibility for worm safety – but don’t worry, it’s nothing too crazy).

You are also guaranteed to receive all the help and support you need to be successful in your vermicomposting efforts. I call it “lifetime” support for a reason! I still enjoy receiving emails from customers who purchased many years ago. So don’t be a stranger!

After you place your order you will be given a special support email address. If you use this address you should hear back from me quite quickly – certainly within 24-48 hours – sometimes within a few hours. I am very active and comfortable online (unlike many in the industry), so getting in touch and staying in touch with me is a breeze. I’ve heard some support horror stories, believe me. Some businesses seem to be very talented in online money transactions, but then suddenly become technically challenged once their customers e-mail them with support questions.

IF for some reason you DON’T hear back from me within a day or two please feel free to NAG me! E-mail gremlins DO exist – and important messages can end up accidentally swept under the carpet from time to time.

The Fine Print

Ok so the title of this section is mostly just a joke.

That being said…

In order to best serve my customers, I DO have some minor requirements that you should know about before ordering. Certain parts of the U.S. can get incredibly hot or cold at different times of year. While these worms are incredibly resilient creatures, there is obviously a limit to what they can tolerate. As such, in order to be able to provide a 100% iron-clad live worm guarantee, you need to A) Be at home to receive them (so they are not left out in the heat or cold), OR B) Allow us to instruct the postal service to hold the package for pickup. That’s it! (see that wasn’t so scary, was it?)

If there are ANY problems with the worms when you receive them, these need to be reported right away. In order to help us determine what might have happened etc, we request that you provide a detailed description (appearance of box and worms, smells etc etc) and multiple photos. Please DO NOT simply assume your worms are dead if they don’t seem lively. After being shipped they will mostly likely need a period of recovery – you’d be amazed by what a day in a moist, quiet bin can do to revitalize them! If you are worried about them please email me (via the special support address) to let me know.

Unfortunately (assuming you have not reported issues initially), we cannot grant refunds or do re-ships on batches of worms that die off within the first few days (weeks etc) of being in your care since any number of things can happen in this situation (improperly set up bin, poor location selection etc etc). Just to provide a sad example, one customer added 5 lb of worms to a system containing only dog poop! Needless to say, the worms died very quickly. (In their defence, this customer did not complain or request a refund though).

Just so you know, the weight of our worms is representative of the measurement taken at the time of harvesting. Please keep in mind however that worms consist mostly of water, and can lose some water weight during transit. We make every effort to keep the worms moist during their journey, but they also require oxygen so they are shipped in breathable bags (which are naturally going to allow for more evaporation). Be assured you are still receiving the same number of worms, and that once they are place into a moist worm bin/bed they should gain most of that weight back fairly quickly. Also, best assured that we are indeed referring to WORM WEIGHT – not the weight of worms and bedding etc. If you’ve ever wondered how some people can offer such low prices for their worms – this, along with zero customer support, are certainly a couple of common reasons.

Additional Info

Our worms are harvested and shipped very early each week (this is a common standard within the industry – helps to avoid worms sitting in postal depots on the weekend). To ensure that your order is included with a weekly batch, place it by Saturday morning at the latest, since it takes time to plan and properly coordinate the weekly harvesting/shipping sessions. It is actually recommended that you place your order before Saturday however (especially larger orders), since on heavy-order weeks there can sometimes be an earlier cut-off.

Our worms reach their destination within 2-3 days the vast majority of the time, so you should definitely receive them before the weekend. If you don’t receive them by Friday mail delivery time, please let me know and I will look up tracking info.

All payments are handled by Paypal or Stripe in a VERY secure manner (these are industry leading online payment handlers). [In fact, we don’t handle ANY financial information ourselves. Please refer to our privacy policy to learn more about the kinds of information we DO receive and how it is handled.]


“I just received my order of 5lbs. of red worms. I am
extremely impressed with the quality and quantity.The e mail I got
from you was very nice. Most people probably wouldn’t be so prompt
about an order, or be willing to offer help. I would also like to add
that if I do buy more worms, it will be from you.Thank you for the
excellent service.”

~ Luke R.

Just a quick follow-up to express my pleasure in receiving the 5-pounds of worms. I think my previous orders to other vendors have only given me 5 pounds of bedding and worms, not a true 5 pounds of worms and then the bedding weight being extra.
The worms look healthy, happy, and ready to feast on the two-week old food scraps we had waiting for them.

~ Jeff B.

“The worms you sent are awesome. I have ordered worms from others and it has always left me wanting. [BUSINESS NAME OMITTED] sent me 4 bags of dirt and said the worm are in there — they are just small and get dehydrated in travel. Yours arrived perfect and I am impressed. So much so I want to repeat my order.”
~ L. Hicks

“”I’m more than satisfied with the worms, and blown away by the customer service. You are truly accommodating! I can’t wait to watch them grow and reproduce!

…quite simply, I just can’t tell you how much you’ve made my week! Thank you to infinity for the worms, the patience, and the emails. The way you handle your customers and your business is of the finest and highest caliber. I hope you have a great Friday, and I will be sure to keep you updated on how the bed is going, and if I can get the laziness out of my shutter-finger, I’ll take some pictures and show you the worms/wormbed.”
~ Richard Blalock

“Hello, Bentley!
I want you to know that the worms arrived and are in the worm bin. Wow, they are really great worms and very, very healthy! They are vastly superior to the pathetic, mostly dead worms I got from [BUSINESS NAME OMITTED]. Thank you for the excellent and fast service! I am 100% satisfied and pleased and you get my highest recommendation! I will place additional orders for my friends as the worms catch on with them…Thank you again for top service and fantastic worms!”

~ Alan G.

Let me thank you for all of the “Beautiful Critters” that arrived. I think the order had multiplied during shipping. I was so happy with them. I can’t begin to make a comparison to [BUSINESS NAME OMITTED] or others worms. It was like night and day…Now I am on my way to happy composting!!!!!”
~ Joan O.

“I appreciate the great customer service that you have. Some of your competitors seem to have no skills at all in this area. I have recommended you to all of the people in my Master Gardener club for that reason.” ~ Richard O.

“I just received worms from you. They were in great shape. Thanks!” ~ Drue Q.

“Thanks for the speedy and great delivery of worms” ~ Joshua H.

“Hey Bentley,
The worms arrived today. They are healthy and lots of them.
Thanks again”
~ Jeannene H.

“I just wanted to thank you for having such wonderful service to your customers. This is my first time attempting to create and manage a vermicompost. It is really encouraging to know that I can contact an expert who is extremely willing to help me. I am really excited about my new project!” ~ B. Rice

“Greetings Bentley!

I just wanted to report back that I received my shipment the other day (a couple of days earlier than anticipated no less) and I was really impressed! I could tell immediately on just lifting the box that this was what one pound of red worms should feel like (so no point in bringing up another anecdote about how I’d been less than impressed with the previous supplier I bought from). I really appreciate your high level of communication and helpfulness–not to mention the obvious enthusiasm throughout your blog.
Please keep it up!
Looking forward to communicating with you more!

A very satisfied new vermicomposter” ~ Ashley G.
