Are cockroaches attracted to heat?

Do cockroaches like heat? Many of us have experienced the unwelcome surprise of finding these pests in our homes.

The answer is yes, cockroaches are attracted to warmth.

Knowing why can help us better manage them.

Cockroaches thrive in extreme temperatures and can be found almost everywhere.

Heat helps them stay healthy and reproduce faster, as well as flee from predators.

So, they often congregate near radiators, stoves, hot water pipes and other humid areas in your home.

What’s more, they can sense temperature changes as small as one degree Celsius – even if your house is cool enough for them not to thrive, they may still be drawn to the slight warmth of other places.

The good news is that there are ways to prevent cockroaches from being attracted to heat sources in your household.

Closing any cracks or crevices where they can enter from outside will help reduce their numbers inside your house.

In addition, regular cleaning and vacuuming can remove any food or water sources that might attract them.

Finally, keeping a consistent temperature in your home will make it harder for these pests to enter or stay inside your household.

By understanding how cockroaches are attracted to heat we can limit their population around our homes and prevent future infestations.
