Who Put A Dryer Sheet in My Mailbox?

The mystery of the dryer sheet in the mailbox. Who would do such a thing? What does it mean, and why would someone put it there? If no one in your household placed the dryer sheet in the mailbox, you can almost guarantee that your mail carrier did. That's right, according to tasteofhome.com, the person who delivers your mail may have placed that dryer sheet in there.

Most of the time they will ask before doing this, however what if we're not home when they bring the mail?

How Does A Dryer Sheet Help Your Mailbox?

Finding a dryer sheet in the mailbox isn't a prank, think of it as preventative maintenance. Fabric softener/dryer sheets help keep bugs out of your mailbox. They are especially helpful in keeping wasps and other pests from nesting in your mailbox. If the mail carrier notices your mailbox is being overrun by wasps, they might place a dryer sheet inside so that they won't get stung when they come back the next day.

Why are Dryer Sheets So Effective?

According to ThisOldHouse.com, dryer sheets use chemicals that are similar to those used in insect repellents. The smell gets powerful when the dryer sheet cooks inside an enclosed mailbox all day. Wasps and bugs trying to get inside turn around when they get a whiff of the dryer sheet and find someplace else to build a nest.
