Chlorinated Hydrocarbons

These are insecticides in fairly common use. They will cause less of appetite and condition with terminal convulsions. A few years ago, these were used on baited corn to kill birds in Great Britain.Wild foxes eating dead birds showed the above symptoms and died. It would appear that foxes are quite susceptible to these poisons. They should not be used on the ranch close to foxes.
