Shrew control: Working products and solutions

Control a shrewShrews are often mistaken for mice, especially when they move into vacated mouse nest sites. Once they are inside the mouse house, they love to eat mice and then live in the place the mouse once lived.

When shrews are present inside your home, they usually leave a strong, unpleasant pungent odor in places where they act. The smell –strong and pungent – comes from shrews’ anal glands. The best way to describe what a shrew smells like is to say that this creature smells like a skunk. As a rule, these animals use the smell as a defense mechanism and to mark their territory.

Despite their small size, pesky shrews have been known to bite humans.

Shrew poison

Poisoned shrewWhen we think of venomous creatures – that come in various shapes and sizes – the first creatures that come to our mind are scorpions, snakes or spiders. Have you ever thought that shrew is also venomous?

Shrew poison is present in the saliva. Shrew produces venom which it uses to disable or kill prey or to defend itself from predators. When this venomous creature bites its victim, the saliva – poison – is introduced into wounds.

As a rule shrew venom is used as a tool for hunting large prey. Unlike venomous snakes who can inject the venom in 1 bite through its fangs, shrews must chew the venom into the prey.

Shrew poison is strong enough to cache prey in a comatose state and to kill mice. What about humans? According to testing, shrew saliva doesn’t have any serious effects on humans. A bite from this small animal would be painful and you may have swelling that lasts for a few days at most.

Wild shrewAlthough these creatures don’t have a negative impact on humans, they are naturally very aggressive and can attack pets or birds. They sometimes get into the homes by squeezing in small entry points. Because of shrews’ aggressive nature and very sharp teeth, they are able to kill and disable animals even larger than themselves.

Safety: Don’t attempt to pick a shrew up if you have it in your home. Remember, they can bite if improperly handled.

Shrews are a persistent pest. If you own a natural yard or landscape which is rich with seed, nuts, wildlife, and insects, chances are high that these critters will like to live there. If left unchecked, shrews will move inside your home. Remove them by sealing off any available entrance holes. Reduce shrews’ infestation by using either live or kill traps in combination with baits.
