Wilco's Ground Squirrel Bait Station is molded of heavy-duty dark green plastic that with-stands abuse. Its design is ideal for ground squirrels, while discouraging non-target animals. It has a child-resistant cap for refilling, and provisions to anchor it to the ground. It is vented to help keep the bait fresh, and has a special baffle to keep the bait dry and in the compartment where it belongs.
