Mole Welfare: Underground Lives and Lethal Control

Moles are frequently killed as garden and amenity grassland pests. Understanding their welfare and the effectiveness of alternatives to lethal control helps reduce unnecessary suffering.

Key Facts

European moles live almost entirely underground in complex tunnel systems up to 200 meters long
Moles are solitary and highly territorial — a single mole can create multiple molehills per day when burrowing through soft soil
Mole traps including scissor and barrel traps cause death by crushing and can be slow if not set correctly
Moles eat primarily earthworms and are entirely insectivorous — they cause no direct plant damage despite creating molehills
Sonic deterrents have limited evidence for effectiveness, while repellents based on castor oil show some promise

Welfare Considerations

Moles are killed routinely because their mole hills are unsightly or because burrowing destabilizes lawn or sporting surfaces. The welfare case against routine mole killing rests on the fact that alternatives exist and that moles are not causing the harms commonly attributed to them — they eat invertebrates, not plant roots. Where killing is deemed necessary, trap design and checking frequency determine how quickly death occurs. Poorly set or infrequently checked traps cause prolonged suffering and should be replaced by instantly lethal methods or alternatives.

What You Can Do

Tolerate molehills in garden areas where they do not create safety hazards
Level molehills and seed the soil rather than killing the moles
If you must control moles, use traps checked at least twice daily to minimize suffering
Try castor oil repellent applications before resorting to lethal control
Advocate for welfare standards in mole pest control contracts including trap check frequency requirements
