Another favourite of the blogger and amateur mole control ‘expert’ is to place sharp objects in the tunnel in the hope that the mole will blunder into them. These may be crushed glass, razor blades, rose thorns, nails… Proponents of this idea often back it up with the entirely incorrect ‘fact’ that moles are haemophiliacs – so once cut they will not clot and so will bleed to death.

In the normal course of life, moles have to contend with sharp stones, pieces of flint, and plant thorns. All of which are found in the soil. This just shows how absurd this idea is.

Additionally, it seems to be a needlessly cruel thing to do.The idea of causing an animal to slowly bleed to death is not only abhorrent, it is illegal! As a pest, land owners are permitted to remove moles, but only using humane methods.

Warning: this method also provides a significant hazard to anyone digging in, or tending to, the garden in the future.
Verdict
A significant chance of injury… to yourself. Also ineffective and cruel.
