Mole Control: Why Ammonia Fails and What Actually Works

The Ammonia Myth

University rodent experts confirm: household ammonia, bleach, lye, flooding, car exhaust, chewing gum – NONE work reliably. Moles don't mind ammonia like humans do.

Mole Biology Matters

• Carnivores: Eat insects, ESPECIALLY earthworms
• Not primarily grub eaters: Urban legend misdirects treatment
• Don't assume grub problem just because you have moles

Shock and Awe: Multi-Weapon Strategy

Trapping (Most Reliable)

• Maccabee gopher traps (farm supply stores)
• Rat traps sometimes work
• Dig to main tunnel (1-2 feet down)
• Newest tunnel = best catch rate
• Bait: carrot tops, fresh greens
• Check daily – persistence required

Fumigation (More Effective Than Flooding)

• Rodent smoke bombs (fair)
• Road flares (better – long-burning, auto supply stores)
• Light flare, stuff in tunnel, seal with dirt
• Watch for escape route, plug it
• Repeat over several days

Deterrents (Variable Success)

• Cats (some swear by them)
• Garter snakes (hard to source)
• Used cat litter/dog waste/urine at tunnel entrances
• Human hair, flavored bubble gum

What to Avoid

• Castor oil + detergent spray: kills moles cruelly
• Lethal traps: illegal in some states as inhumane

Integrated Approach

Diligent, multi-method assault works best. It's a war of wills – persistence wins.
