Some people have been opening their mailbox and finding a fresh smelling surprise!
A postal worker took to reddit to reveal the reason, not wanting to get stung by bees!! Postal workers have to be extra careful when opening mailboxes because bees often use them to build their nests.
He said:
"So please, if you one day randomly see a dryer sheet at the back of your mailbox, just know that your carrier more than likely put it there to deter these Satanic creatures from building their home in it."
And if you're feeling extra nice, add one to the back of yours!
