Things You'll Need
Instructions
Make the areas around the grounds wet and moist where you suspect nightcrawlers are dwelling. Use a sprinkler, hose or buckets of water to make the dirt muddy and squishy for easy picking during the nighttime.
Use a flashlight with a red filter to locate the nightcrawlers after dark. Regular flashlights will blind them and cause them to hide deep beneath the soil. Check underneath rocks, leaves and any other aboveground objects for nightcrawlers. Use a small garden shovel to unearth the soil to check for nightcrawlers.
If they are buried in the muddy soil, pick them out slowly and gently with your index finger and thumb. If you have trouble unearthing them, pour more water on the area to moisten the soil.
Place the nightcrawlers in a temporary holding bucket filled with soil.
