Our Wilco squirrel bait station is molded of heavy-duty dark green plastic that withstands abuse. Its design is ideal for ground squirrels, while discouraging non-target animals. 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. Has child-resistant caps for refilling and anchor points. Always secure poison in bait stations so that it is not available to children, pets or wild animals. When placing bait stations outside, consider all areas where bait should be placed such as wood piles, storage sheds and fence rows. They should be placed about 50 ft apart around buildings or along landscaped areas surrounding buildings. Grain baits can no longer be broadcast on fields, they must be used in bait stations.
