Why Do Skunks Spray?

Skunks can release a foul-smelling odor into the atmosphere.  If you have ever smelt it, you will never forget it.  I had an email asking me why skunks spray, and if you want to know why, please read on.

Skunks have many predators and spray as a mechanism to keep themselves safe.  Skunk spray is not dangerous to humans.  It is not toxic and does not transmit any diseases.

Skunks are mammals that are native to North and South America. They vary in size according to the species and have a standard fur color of black and white. Some skunks have brown or grey fur. Another common characteristic of the skunk is that they are born with stripes.

Why Do Skunks Spray?

Skunks spray to protect themself and ward off predators. Skunks are small mammals and attractive to several predators.  A major way they can defend themselves to survive is through the awful smelling spray.

There are many predators, including coyotes, badgers, bears, and wolves. A number of these predators rely on their keen sense of smell to detect prey and to hunt. 

Animals with an advanced sense of smell will find the smell of the skunk spray unbearable and overwhelming. 

For this reason, predators will not be able to go anywhere near them.  They also wouldn’t perceive the skunk as a tasty meal.

The spray of the skunk is a weapon that they reluctantly use.  Before a skunk can spray an enemy, the skunk has specific warnings.   First, the skunk has a bold black, and white coloration meant to make its appearance memorable. 

Many predators would not go near a skunk out of fear for its spray if witnessed previously. 

Threatened skunks give other warnings, including hissing.  If this doesn’t work, they will stomp their feet several times before portraying threat postures, such as raising their tails high.

If the warning signs don’t work, they turn and face their anal glands towards their target. This is the last warning to the offender before the skunk unleashes the spray.

Skunks do not normally spray other skunks. However, males might do this when fighting over partners. 

When fighting over territories and den space, skunks prefer to do so with their teeth and claws.

When Do Skunks Spray People?

Skunks will spray humans for the same reason they will spray a predator.  This is when they feel threatened or in danger. 

It is a bad idea to disturb a skunk intentionally. If you spot one nearby, leave the animal alone, and go your way. Otherwise, you may be walking around with a stinky odor.

People accidentally frighten skunks when they walk close to their dens without knowing it. These animals live in burrows that they dig for themselves or take over an abandoned one. 

The den is usually covered to keep away predators. If you walk over its dens and unintentionally surprise it, then you might end up getting sprayed. Skunks do this as a defensive measure.

How Can I Avoid Getting Sprayed?

If you encounter a skunk somewhere, leave it alone.  Do not walk towards them or make any sudden movements.  Skunks will only spray you when they perceive you as a threat or if surprised.  Skunks do not want to be bothered, so try to stay away from them.

What Is Skunk Spray?

The spray of the skunk is a chemical liquid that contains organic compounds referred to as thiols. 

The foul odor of the spray is attributed to its constituents. Thiols are chemical compounds consisting of one sulfur atom that is bonded to a hydrogen atom.

The compounds are chains of carbon and hydrogen with sulfur and a hydrogen thiol group attached on one end.  They are also volatile. This means that they can disperse efficiently in the air.  Due to the volatility, the human nose picks it up quite fast. 

When the spray from a skunk comes into contact with water, the compounds are rearranged into a potent configuration. 

When you or your pet gets sprayed by a skunk and bathes in water, the smell only worsens.  The more you try to wash off the spray, the smellier it becomes. 

This is probably a good reminder that humans or pets should not mess with skunks.

How Do Skunks Spray?

Skunks have two scent glands located on each side of the anus. The glands produce and store the powerful liquid that they spray on potential threats or predators. Each gland is connected to an external squirter found beneath the tail on each side of its anus.

There are muscles located just next to the spray glands. These anal muscles help skunks eject the stored spray and shoot it out. They are extremely good at aiming, rarely missing the target. 

A skunk is capable of shooting spray with high accuracy reaching targets as far as 3 meters away.

The anal scent glands contain about 15 cubic centimeters of spray. Skunks have enough spray use to 6 times. 

It can take ten days before they can produce more of the spray.  Due to this, the spray is not something that skunks are willing to use unless they have to. 

When they deplete the stored spray in the scent glands, they are left vulnerable to predators. At this time, the skunk has no other practical way to protect itself and easily fall prey. 

Mostly, they will try to discharge only small amounts at one time to preserve as much spray as possible.

Is Skunk Spray Dangerous?

Skunk spray is not dangerous to humans.  It is not toxic and will not cause you any complications. Their spray does not transmit any diseases, and it will not burn your skin either.  

Skunk spray is an extreme smell.   Once you have smelt a skunk, you will never forget the smell.

The smell is bad enough to trigger nausea and even vomiting.  This shouldn’t be surprising, considering the spray is a chemical defense that has the capability of warding off predators as large as a bear, wolf, or coyote. 

If the liquid happens to get into your eyes, it can cause significant irritation and, at times, temporary blindness.  In this situation, seek medical help to avoid issues with your eyes.  Other than getting it into your eyes, skunk spray is not too bad, apart from the smell. There is no need to worry that skunk spray will cause you harm.
