Managing Mass Frog Invasions in Pacific Northwest Gardens

Question: Tiny green frogs (quarter to silver-dollar size) are everywhere—falling on heads, covering walls/windows, entering house. We have a nearly dry 5-acre drainage pond. How to kill or repel them?

Answer: Frogs Indicate Healthy Environment—Manage, Don't Eradicate

Global frog populations are declining due to pollution/habitat loss. Their abundance suggests a healthy local ecosystem. No toxicants are registered for frogs.

Exclusion: Keep Them Out of the House

• Inspect entire structure top-to-bottom; seal/screen all gaps ≥¼ inch
• Caution: Ensure no bats or other wildlife are inside before sealing
• Use rat-sized glue boards indoors; capture/release outside
• See structural inspection course

Habitat Modification (Reduces Numbers)

• Reduce insect prey: Manage outdoor lights (attract insects), fix drainage
• Reduce shelter: Remove dense ground cover, debris piles near house
• Drier areas = fewer frogs
