Mole Control in Seattle: Humane, Multi-Tactic "Shock and Awe" Approach

Managing Moles Without Killing: A Persistent Homeowner's War

A Seattle homeowner (Jeff, two F's) finds perfect dirt piles with silver-dollar holes and tunnels. Wants removal without lawn damage, killing, or return. Previous answer covered mole vs. gopher biology, trapping, flooding, smoking, repellents.

Follow-Up: Washington State Specifics

WA has unique omnivorous mole variety
State resource: wdfw.wa.gov/wlm/living/moles.htm (wealth of info)
Expert hasn't read fully but recommends it

Integrated "Shock and Awe" Recap

Trapping: Box/Maccabee traps in fresh tunnels (1–2 ft deep); carrot tops bait; check daily
Flooding: Easy but temporary unless mole drowns
Smoking: Road flares (auto store) in tunnels, seal both ends; more effective than smoke bombs
Predators: Cats, garter snakes
Repellents: Castor oil/detergent (harms moles), used cat litter/dog waste/human hair/bubble gum (psychological)
Persistence: Multi-weapon assault over days

Jeff tried red pepper flakes (failed); will try flares next. Expert wishes luck.
