3. Weather Forces That Drive Slugs Indoors\
Slugs normally live outside. They come inside only when outdoor conditions become uncomfortable.
Slugs invade homes most often during:
- Prolonged heavy rain
- Flooding
- Sudden temperature drops
- Extremely humid summers
If your yard holds water or stays soggy, slugs migrate to higher, drier shelter—which may be your house.
Outdoor risk factors:
- Mulch pressed against the foundation
- Overwatered gardens near walls
- Ivy or bushes touching siding
- Clogged gutters causing water runoff
What to do outside:
- Redirect downspouts away from the foundation
- Keep mulch at least 12 inches from walls
- Trim plants regularly
- Improve soil drainage
Your home should never be the driest place nearby.
