Why do people put a dryer sheet in the mailbox?

It is important to note that the practice of using dryer sheets in mailboxes is primarily a preventative measure. Placing a dryer sheet inside a mailbox that is prone to wasp or yellowjacket nests helps to keep them from establishing a home there in the first place. However, if a large nest has already been formed, it is advisable to remove it before implementing this method to prevent a potentially dangerous situation.

When utilizing dryer sheets as a preventive measure, it is recommended to periodically check their effectiveness. If the scent has faded or is no longer noticeable, it’s time to replace the dryer sheet. This ensures that the repelling properties remain strong. While this method may not guarantee complete eradication of wasps and yellowjackets, it has proven effective in deterring them from choosing a mailbox as their nesting ground.

Discovering a dryer sheet in the mailbox might initially appear perplexing, but it serves a practical purpose—keeping wasps and yellowjackets at bay. By utilizing scented dryer sheets, individuals are able to prevent these stinging insects from building nests inside mailboxes, thus avoiding painful encounters during routine mail retrieval.
