Moles can cost a farm a great deal through contamination of silage, reducing grazing
area, injuring livestock, damage to machinery and damage to young plants.
Silage contamination through molehills is potentially the most costly. This is caused
by bacteria present in the soil, mainly clostridium and listeria. Clostridium leads
to the formation of butyric acid, spoiling silage. Listeria causes litseriosis, often
in the form of encephalitis or meningoencephalitis (cilrcling disease) but also causing
septicaemia, abortions and silage eye.
A program of trapping can help with such problems. In the hands of a skilled mole
catcher the use of traps is the only viable method of control currently available.
Results are highly effective, swift, and easily verifiable.
