Why Don’t Worms Crawl Out of the Bin?

A good question from Mark:

Quick question: Why don’t the worms crawl out of the holes
in the bottom and sides of the worm bin?

Hi Mark – sometimes the worms WILL crawl out, but generally only if the conditions outside the bin are to their liking, or they are in a real state of distress.

Let me see if I can illustrate with an analogy. Imagine it is the coldest day of the year, the winter winds are howling outside your home and the snow is coming down by the bucketload. All you have to wear are your pajamas. What is the likelihood of you wanting to open the door and head out into that, rather than stay inside where it is nice and warm, and there food in the fridge and a game on the bigscreen TV.


Seriously though, the bottom-line is that the condtions outside of the bin are usually pretty harsh for a worm – you’ll notice that if they DO escape from the bin, they will generally dry up and die quite quickly. Aside from low humidity, light is also another serious deterrent.

Hope this helps!
