Do cockroaches disappear in winter? No, cockroaches do not die or disappear in winter. Cold slows them down and makes them move to warm places inside the home: the kitchen, behind the fridge and near the water heater. That is why you see fewer, but they are still there and breeding, and they show up strongly once the weather warms.
Where do cockroaches go in winter?
- Behind the fridge and oven: the motor gives warmth all day.
- Near the water heater and hot water pipes.
- Inside kitchen cupboards and under the sink.
- In drains and manholes, which are warmer than outside.
- Inside electrical appliances such as the microwave and kettle.
Why you see fewer cockroaches in winter
- They move less when the temperature drops.
- They breed more slowly in cold spots.
- The large (American) cockroach comes out of drains less.
- But the German cockroach lives inside the warm home and is hardly affected by winter.
Cockroaches in winter by type

Is winter a good time for control?
Yes, and it is the best time:
- Cockroaches are gathered in a few known places.
- Bait reaches them easily, as they stay close to their shelter.
- If you clear them now, numbers will not surge in summer.
How to control cockroaches in winter
- Apply cockroach gel in small dots behind the fridge, under the sink and in cupboard corners.
- Cover drain openings with fine strainers, and pour water into unused floor drains.
- Dry out moisture under the sink and fix leaks.
- Do not spray over the gel, as spray makes cockroaches avoid it.
- Spray a residual insecticide around manholes and entry points outside.
