Abstract
A trap for earthworms which comprises a capture chamber having a bottom, inwardly sloping sidewalls and pivotal louvers defining a horizontal top of the capture chamber. Earthworms leave their burrows at night, or when the burrows are soaked with water, and crawl onto the pivotal louvers which rotate, causing the earthworms to fall into the capture chamber. A canopy may be provided over the trap to shelter it from rain or water sprinklers.
Claims3
A trap for harvesting earthworms comprising:
- a trap chamber defined by a base and four inwardly sloped solid sidewalls having inner, outer and top surfaces;
- a plurality of horizontally disposed louvers having flattened surfaces, said louvers being pivotally supported on the top surfaces of the inwardly sloped sidewalls, the outer surfaces of the inwardly sloped sidewalls and the flattened surfaces of the louvers being sand-coated to enable effective movement of earthworms up the sidewalls onto the louvers, the into the trap;
- and each louver having first and second end spindles disposed on opposite top surfaces of the sidewalls, said end spindless having a flattened oval contour when viewed from the side along the axis of the corresponding louver, whereby the associated louver tends to return to a horizontal plane when at rest after rotating from the weight of an earthworm falling into the trap chamber.
