Does Rain Bring Out Rats? (Yes — They Don't Like Wet Basements Either)
Big storm, flooded yard… and suddenly a rat sprinting across the patio. Coincidence? Nope.
Quick answer: Yes. Heavy rain floods rat burrows and storm drains, forcing rats to higher, drier ground — often sheds, garages, basements and under decks. That’s why many people notice rats right after big storms.
What rain does to rats
| What happens | Result |
|---|---|
| Burrows flood | Rats leave their nests and look for new shelter. |
| Sewers and storm drains fill | Rats move up and out. |
| Food washes around | Garbage and compost spill, giving them new reasons to stay. |
| Cold rain in fall | Rats push indoors looking for warmth. |
After a storm, check
- New holes along the foundation, under sheds, decks and slabs.
- Gnawing or gaps at garage doors and basement windows.
- Droppings in garages and basements (capsule-shaped, about ½–¾ inch).
- Tipped garbage cans and torn bags.
Tip: Fill suspicious burrow holes loosely with soil after a storm. If they’re dug back open the next day, rats are active.
