Purina Worm Chow---Does it really work???

I have seen some people talking about the Purina Worm Chow. I searched Ebay and found 2 people that are selling it in different packaging. There are links to those items at the end of this blog. How do you know if you are getting the real deal, or just a home-made bag of stuff? Is the real stuff even that good, or is it just an added expense for the vermicomposter? I would like to hear some responses from people who have used the Purina worm chow. What did you like or dislike about it? Does it really make a difference in how fast worms reproduce and eat?

Here is what I found on Ebay:

Purina Worm Chow 10 pounds for $19.75 Free shipping--------click here

Purina Worm Chow 15 pounds for $25.00 including shipping--click here

Purina earthworm chow comes in 50 lb. bags and costs $13-15. It's not exactly easy to find, so people repackage it in smaller bags and sell it for the various prices you've found. I have not done a controlled experiment to see if the worms reproduce any faster, but there is no doubt they eat it faster than just about any "normal" worm food. If you only want to process food scraps, then it's not worth buying. If you have a lot of worms and want to produce a lot of VC or sell worms and VC, then it's well worth $15. I posted a blog recently on how to find a Purina dealer that sells it.

I bought a 1 pound bag of the worm chow to try. The cost was $6.95 including shipping. If I like how it works, I may buy a larger quantity later on.

The bag Larry sent me was ~9 lbs. It fit in a USPS Medium Priority Mail flat rate box, which costs ~$11 to send anywhere in the U.S. If you split a 50 lbs. bag into 6 portions and ship 5 of them at a cost of $55, the total cost would be ~$70. Split that between 6 people and it's ~$12 per 8.3 lb. portion ($1.50/lb.) Basically the 15 lbs for $25 deal ($1.67/lb.) posted above is pretty fair. They're marking up the worm chow 100% and charging the cost of shipping (probably a Large Priority Mail flat rate box).

If I want to buy more, I will probably by some from you guys if you are selling it.

Micah, Do not buy Purina Worm Chow online. Find a Purina dealer in your area & order a 50 lb bag. I paid $13.87 for a 50 lb bag that has lasted me all year. The worms love it! I usually feed my worms fruit & veggie scraps & aged horse manure and I only top-feed about 6 ounces of worm chow about every 3 or 4 days just to diversify their diet. Don't mix the worm chow with the bedding because it can go sour. I've found that the worms really go feeding crazy when I add a couple ounces of powdered egg shells...Sprinkle the chow on top & mist it with water.

I wouldn't say the above worm chow prices are "rip offs". $10.70 of the first and $14.50 of the second is the cost of postage. If you assume the cost of the worm chow alone is 30¢/lb., then the cost of 10 lbs. is $3 and 15 lbs. $4.50. The seller is making a profit of $6 for each shipment. Even if they can get a bulk discount for the worm chow, that would only add another $1-2 per order. You'd have to sell a lot of those to make it worth the time and energy to re-bag and pack the orders for shipping.

Of course buying a 50 lb. bag would be cheapest if you had a source nearby. Just remember that it will take you years to use that up unless you have a lot of worms. I'm using it to feed ~12 lbs. of EEs and EHs and I'm using it at a rate of ~1 lb. per month.

I wouldn't use it. Their dog food is horrible for dogs so I doubt their worm food is good. Please don't feed your dogs, cats, or worms Purina anything.

Actually, I have been using the purina chow for about 3 weeks now and I am getting great results. They are eating more and breeding more too. Just the other day I opened up my worm tray and there was a worm orgy going on.

Hi Micha I did buy Purina Worm Chow on line and the worms love it. I tried to find a place close by but had no luck. I sprinkle it over the food I put in the bin.
