During the summer, some people apparently have been finding dryer sheets stuck inside their mailboxes. A postal worker took to Reddit to inform people of the truth behind the dryer sheets. Posting under the name Istrx13, the user explained that the dryer sheets are used to keep wasps away. One user wrote, "I'll be putting a dryer sheet in there tomorrow. We learned long ago to put a few dryer sheets under the tablecloths on the patio."
