Worms Escaping From the Bottom
Leachate is normal to see in the first few days, but you do not want to see it on an ongoing basis. Worms are attracted to moisture, so if you end up adding too much via watering or by adding lots of water-laden food waste without adding a bunch of dry bedding, then that excess moisture makes its way to the bottom and "pulls" the worms down with it. For the new 2021 Version of the Urban Worm Bag, worms could potentially make their way past the velcro bottom and on to the floor.
Worms Escaping From the Top
You may find that worms are crawling up the walls of the Urban Worm Bag and some may escape between the zippers.
As mentioned above, worms are attracted to moisture, so if there is condensation on the walls or lid, the worms will happily explore these surfaces.
If worms are escaping out of the top of the bin, you can try placing a cotton ball in between the double zippers on top.
There are many reasons why you might find worms escaping, but it doesn't mean you're doing anything wrong.
