5. Scented Mulch Additive for General Pest Control

Integrating soap shavings into your mulch can create a slow-release pest-deterrent zone around garden beds. This method provides a more general, ground-level barrier against a variety of crawling and small pests.

1. Preparation and Application:

Grate a bar of Irish Spring soap. As you apply a fresh layer of mulch (wood chips, straw, bark) around your plants, sprinkle the soap shavings lightly and mix them into the top few inches of the mulch. Avoid creating thick clumps of soap.

2. Target Pests:

This technique is often cited as a deterrent for burrowing animals like moles and voles, as the scent may disturb their sensitive noses underground. It may also discourage ants, slugs, and other ground-crawling insects from traversing the area to reach your plants.

3. Renewal and Watering:

Watering the garden will slowly dissolve the soap, releasing the scent into the soil and air. You will need to replenish the shavings every few weeks or after significant rainfall to maintain the effect.
