I've found that this technique is a bit hit and miss - right time of year, right conditions and it will work well but in less than ideal conditions it might not turn up a single worm. Your mileage may vary. Still, an entertaining video. Thanks for sharing.
Agreed, depends on your locale, and soil conditions also. This time of year in the Midwest, It is a sure thing, but by mid August it can take a few days of preparation by soaking the same spot with water a few days in a row. I remedy the situation by making up multiple farm boxes while the harvesting is good.
The next episode is currently filming, it will be "Brine Shrimp for the Lazy Chapter 1". This one will have three chapters as there are two methods of hatching I wish to demonstrate, and a bit on decapsulating cysts the safe way.
Future topics will include Daphnia, White Worms, Vinegar Eels, Crickets, and Fruit Flies.
I am going to do a few on Aquarium basics also, such as building custom fit fruit fly (and pinhead cricket) proof screen tops (Including bow front and other oddly shaped tops), Air pump repair, larvae and microfood safe disposable filters from recycled materials, and aquarium cycling.
If there is a topic you would like to see covered, post in this thread. I get really bored in the summer, and this little endeavor helps to pass the time.
