The most obvious problem with skunks is their incredibly noxious smell.  If sprayed onto buildings or surfaces, the odour can remain for weeks or even months in high enough concentrations.  But the smell is actually of lesser concern when compared to some of the property damage and health risks these animals can cause.

Property Damage

Burrowing under foundations: In the wild, skunks burrow underneath the base of trees.  However in urban settings, they will burrow underneath solid foundations which can cause thousands of dollars in damage should structural elements shift or crack.

Chewing: If necessary, skunks will chew through wood and siding to make their burrows.

Lawns and gardens: Aside from garbage, skunks eat a lot of insects and grubs.  It is not uncommon for skunks to dig up gardens and lawns in their search for food.

Health and Safety Risks

Rabies: Skunks have been known to carry and transmit the rabies virus.  The proportion of skunks with rabies is greater than that seen in fox or raccoon populations which is why this is of concern.  Infected skunks cannot be distinguished from healthy skunks so any possible contact with skunk saliva should be taken very seriously.

Noxious spray: Aside from the smell, the skunk spray can cause nausea, vomiting and even blindness because it contains sulphuric acid.
