This instructable was inspired by my dog, "Hunter".
One day as i was washing him with his special dog shampoo, i noticed that there were allot of worms all over my feet, and on closer inspection i noticed that in a 2m circle all around earth worms were shooting from the ground, and wriggling over the grass and going away to who knows where.
This was opposed to much further away where the water from the hose had reached but the soap had not.
Anyway, on another day when i washed the dog, within 2 minutes of washing off the shampoo, it happened again, worms were everywhere.
This instructable, is about how to extract large amounts of worms from the soil, and also identifying a suitable area to extract the worms from!
In the included video you'll see that it only takes about 10 seconds before the worms come from the soil, times may vary depending on how much soap or shampoo you use and how many worms and how close these worms are from the surface, as well as the soil density which enables free movement.
Remember not to take too many worms from one area in your yard or it may negative effects on the soil ecology, its very easy to severely deplete worm numbers, so be sure not overdo it. and remember, the soapy water will repel worms for about a week, so, it wont work in the same spot and avoid doing it in the same spot anyway.
