Even though they seem to appear out of nowhere, slugs follow their sense of smell. Forgotten crumbs, a poorly closed bin, pet food left out overnight, or garden waste stored near entrances: all of these can attract them.
A simple tip: clean the floors before bedtime, seal food containers tightly, and keep compost away from walls to minimize any potential sources of attraction.
Slugs, revealing a balance to be restored

Harmless, they are primarily natural indicators. Their presence often signals an imbalance: too much humidity, insufficient ventilation, or neglected maintenance. By observing them, you have the opportunity to correct these minor issues before they become more problematic and to sustainably improve indoor air quality .
How to get rid of it gently

There's no need to resort to harsh solutions. Wearing gloves, you can gently move them outside. Copper tape placed near entry points acts as a natural repellent, and keeping surfaces dry remains the best prevention. Salt, on the other hand, should only be used outdoors, away from interior floors and surfaces that it could damage.
An occasional slug is nothing to worry about, but repeated visits warrant attention. By addressing these issues, you'll create a healthier, more comfortable, and more peaceful environment for your home—and yourself.
