Why Are Earwigs in Your Mailbox?

If you’ve noticed earwigs in your mailbox, you might be wondering why these little critters are making themselves at home.

While it might seem like an odd place for them to congregate, there are actually a few reasons why earwigs might be attracted to your mailbox.

Why Are Earwigs in Mailbox?

Firstly, earwigs are drawn to damp and dark environments, which makes mailboxes a prime location for them.

If your mailbox is located in an area that tends to be damp or receives a lot of shade, it can create the perfect environment for earwigs to thrive.

Additionally, if there are any small cracks or crevices in your mailbox, it can provide easy access for earwigs to enter and make themselves at home.

They may even use your mailbox as a place to shelter during the day and venture out at night to forage for food.

Another possible reason for earwigs in your mailbox is simply coincidence. If there are other areas around your property that are already infested with earwigs, they may simply be wandering around and end up in your mailbox by chance.

How Do Earwigs Get Into the Mailbox?

Earwigs are pretty crafty little creatures, and they’re known for their ability to squeeze into tight spaces.

Mailboxes, with their small openings and dark interiors, are the perfect place for these little critters to set up shop.

But how do they actually get in there? It turns out that earwigs are skilled climbers, and they’re able to scale the sides of mailboxes quite easily.

Once they reach the top, they can use their pincers to grip the edge and lower themselves down into the box.

Of course, not all earwigs are created equal when it comes to climbing skills. Some are better at it than others, and some mailboxes are more difficult to climb than others. But in general, if there’s a way for an earwig to gain access to your mailbox, they’ll likely find it.

So Earwigs are able to get into mailboxes by using their climbing abilities to scale the sides of the box and lower themselves inside. 

Can Earwigs Cause Damage to Your Mailbox?

While earwigs themselves may not cause significant damage to your mailbox, their presence can be a sign of a larger problem.

Here’s a list of potential damage earwigs can cause to mailboxes.

Wooden mailboxes

Wooden mailboxes can be vulnerable to damage from earwigs. While earwigs are not known to chew through wood, they can burrow into the wood and create small tunnels. Over time, this can weaken the structure of the mailbox and potentially cause damage.

Additionally, if the wooden mailbox is exposed to moisture, it can become a breeding ground for earwigs and other pests.

Metal mailboxes

Metal mailboxes are generally more durable than wooden or plastic mailboxes and are less susceptible to damage from earwigs. However, if a metal mailbox has already been damaged or is starting to rust, earwigs may be attracted to it and make the damage worse.

If the mailbox is not properly sealed, earwigs may be able to enter through small openings and potentially cause damage.

Plastic mailboxes

Plastic mailboxes are more vulnerable to damage from earwigs because earwigs are known to chew through plastic. If the plastic mailbox has cracks or holes, earwigs can use these to gain access to the inside of the mailbox and potentially cause damage.

And plastic mailboxes can become brittle and weak over time, especially if they are exposed to direct sunlight or extreme temperatures. This can make them more susceptible to damage from earwigs and other pests.

Moisture damage

Earwigs are often attracted to mailboxes that are damp or moist. Over time, this moisture can cause damage to the mailbox, particularly if it is made of wood or has metal components that can rust.

In addition to potential damage to the mailbox itself, earwigs can also cause damage to your mail. They are known to sometimes feed on books and paper products, so if you receive newspapers or other paper mail, earwigs may be attracted to it and potentially cause damage.
