The first cold snap changes where roaches want to be. Warm kitchens and baths look pretty good to them.

Why do roaches move indoors in the cold?

Roaches want three things: warmth, water and food. When nights drop, outdoor spots get harsh. Your house offers all three.


Some roaches already live indoors all year. Others live outside in warm, damp places and move in when it gets cold.


Where do they get in?

  • Gaps around pipes under sinks and behind toilets

  • Door sweeps and thresholds that do not seal

  • Cardboard boxes and grocery bags

  • Laundry rooms, garages and basement drains


Is it a sign my home is dirty?

No. Clean homes get roaches too. A crumb or a drip is enough. We never judge. We just help you find the cause.


What can I do today?

Fix drips. Wipe counters at night. Seal food. Take trash out. Break down boxes and recycle them quickly, because roaches like to hide in cardboard. Seeing one in daylight or finding droppings means it is time to call.


Quick Answers

Do roaches die in cold weather?

Outdoors, many do. Inside a heated home, they stay active.


Why do I see roaches at night?

They are most active in the dark. Seeing one in the day can mean a bigger group is nearby.


Are all roaches the same?

No. German and American roaches live in different places and need different answers.
