Every year, as the nights turn cooler, pest-control calls go up. The reason is simple: rats feel the cold too, and the warmest places around are inside our homes.
Why the cold drives them indoors
Outdoors, cooler nights mean rats burn more energy staying warm, while food gets harder to find. A home offers both warmth and food in one place. That makes this the season when an occasional visitor turns into a resident.
The warm spots they head for
- Behind the fridge — the motor keeps it warm all night.
- Near the geyser or water heater.
- The false ceiling — warm, dark and rarely disturbed.
- Kitchen cabinet bases — close to food, out of sight.
- Storerooms — cartons and clutter make perfect nesting material.
Get ahead of it
- Seal gaps — anything wider than 2 cm, especially where pipes enter walls.
- Store food properly — sealed containers, no open grain sacks.
- Declutter storerooms — less nesting material, fewer hiding spots.
- Make problem zones uncomfortable — before rats settle, not after.
Timing is everything: rats that haven't settled yet are far easier to discourage than a family that has already nested. The EchoRepel Ultrasonic Rat Repellent keeps kitchens, storerooms and ceiling access points uncomfortable, without poison. For where to look, see 9 surprising places rats hide in your home.
