Owls - Nature's Best Pest Control

Project by Lauren Somerville Richardson Bay Girl Scout

Owls like the Great Horned, Barn, and Western Screech Owls do more than provide beautiful nightly calls—they're nature’s best pest controllers! A single Barn Owl can eliminate over 1,400 rodents a year, offering a natural solution without toxic chemicals. Anticoagulant rat poisons, commonly used for rodent control, can cause slow, painful deaths for wildlife, pets, and other unintended victims. By avoiding these poisons and installing owl nesting boxes, you help protect local wildlife and support owl conservation.

Lauren Somerville, a Marin Catholic High School Senior and Richardson Bay Girl Scout, is raising awareness about the dangers of rat poisons and promoting owls as a natural alternative for her Girl Scout Gold Award. She has partnered with Raptors Are The Solution and All About Owls and has provided owl boxes to Marin Catholic High School, Strawberry Point Elementary School, and Richardson Bay Audubon Society.

Walk and Roll Wednesdays

First Wednesday Every Month (schools may vary)

Establishing a designated Walk/Roll Day at your school keeps the momentum going after International Walk and Roll to School Day. Students and families have a designated day each week, such as Walk/Roll Wednesdays.

This is a great way to ingrain walking/bicycling into your school culture. Fun themes help make the enthusiasm for walking and rolling a year-long treat. It can also be a catalyst to encourage weekly walk and roll days, walking school buses, and bike trains.

For additional information on how to travel to school safely and sustainably check out Marin Commutes
