8. Rodent Repellent in Sheds and Storage Boxes

Mice and rats seek out sheds, garages, and storage boxes for shelter and nesting materials. The strong scent of Irish Spring is believed to be offensive to these rodents.

1. Placement Strategy:

Unwrap bars of Irish Spring and place them whole or cut in half in areas where rodents might enter or nest. Key locations include corners of the shed, near stored seed bags, in storage boxes containing camping gear or holiday decorations, and around the engine compartments of lawnmowers or other equipment in storage.

2. Refreshing the Scent:

The scent will eventually fade. Scratch the surface of the soap bars with a knife every few months to release fresh fragrance, or replace them every 6-12 months. For best results, use this in conjunction with good sanitation—sealing food sources and blocking entry points.

3. A Note on Efficacy:

While many gardeners and homeowners swear by this method, rodent pressure and motivation can vary. For severe infestations, it should be considered a supportive measure rather than a standalone solution.
