How to Set up a Berlese Funnel
Many tiny arthropods make their homes in leaf litter, rotting wood, or soil. They can be coaxed to leave their habitat if you make conditions uncomfortable enough (but not lethal). Since their preferred habitat is dark, cool, and moist, you can force them out by applying light and heat. Gather a small sample (in a small bucket or bag) of leaf litter, wood, or soil. Indoors, set up a contraption called a Berlese funnel. These are available from biological supply houses, too, but are easy to put together yourself.
