Is Climate Change Making Spiders Bigger?

Climate change is one of the most pressing issues of our time, with its effects being felt in many aspects of our lives. While we are all familiar with the impacts of climate change on the environment and our weather patterns, there is another, lesser known effect of global warming: spiders are growing larger.

How is Climate Change Affecting Spiders?

The increased temperatures associated with climate change are causing spiders to grow larger. This is due to a phenomenon known as “thermal acclimation”, which refers to the way in which an organism adapts to its environment. As temperatures rise, spiders are able to retain more of the energy from their prey, leading to increased growth.

What Does This Mean for Us?

While larger spiders may not be the most appealing creatures, it is important to remember that they are also important predators in our ecosystems. By controlling insect populations, they help to keep our environment in balance.

Larger spiders also have the potential to become a nuisance if they start invading our homes. While it is unlikely that they would pose a threat to humans, they could be a nuisance and may require pest control services to remove them.

Can We Do Anything to Stop This?

The only way to prevent spiders from growing larger due to climate change is to reduce global warming. This means reducing our emissions of greenhouse gases, as well as switching to renewable energy sources.

We can also take steps to reduce the number of spiders in our homes. Sealing up any cracks or crevices in our walls and windows can help to prevent them from entering. Additionally, eliminating sources of moisture, such as standing water, can help to reduce the amount of spiders in our homes.


Climate change is having a significant impact on our environment, and spiders are no exception. Spiders are growing larger due to increased temperatures, and this could lead to an increase in nuisance spiders in our homes. We can reduce this risk by reducing our emissions and sealing up our homes.
