Is Climate Change Making Pests Worst?

There’s no doubt that climate change is happening. While we are feeling the effects of climate change in many ways, what’s less clear is how climate change changes the world around us – including how pests behave. This blog post will explore some of the latest research on how climate change impacts pest behavior and what we can do to prepare for these changes.

What is Climate Change?

Climate change is the long-term alteration of temperature and typical weather patterns in a place. It is a change in the weather that occurs worldwide, such as an increase or decrease in rainfall and temperature. Climate change has been connected with damaging weather events such as more frequent and intense hurricanes, floods, downpours, and winter storms. Together with expanding ocean waters due to rising temperatures melting polar ice, the rising sea level has begun to damage coastlines due to increased flooding and erosion.

How Does Climate Change Affect Pests and Diseases?

There are many ways in which climate change can affect pests and diseases. Some of these effects are direct, such as an increase in temperature leading to an increase in the number of days a particular pest can survive and reproduce. With increased global trade, pests and diseases are becoming more prevalent worldwide. As the world gets warmer, pests can move into new areas to find the conditions they need to survive and thrive. This can lead to problems for local plant and animal species that have not evolved defenses against these new invaders.

A changing climate can also affect pests and diseases indirectly by altering the timing of their life cycles. For example, warmer winters may cause some insects to emerge from hibernation earlier than usual, giving them a head start on their springtime activities. This could allow them to complete their life cycles more quickly, resulting in multiple generations in a single year – which could lead to population booms. Changes in precipitation patterns can also have an indirect effect by altering the habitat in a favorable or unfavorable way to a particular pest.

Some of the most well-studied examples of how climate change can impact pests and diseases include:

• Ticks and Lyme Disease. The life cycle and prevalence of deer ticks are strongly influenced by temperature, which has led to an increase in Lyme disease. The warmer it gets, the more ticks can thrive in a given area, increasing their chance of carrying an infection. 

Studies show that climate change has helped make these pesky insects even more dangerous. Ticks can now survive and reproduce in areas where they were previously unable to, leading to an increase in the incidence of Lyme disease in many parts of the United States.

 Mosquitoes and West Nile Virus. The increase in climate change is causing many problems, including an increased risk of human exposure to the West Nile Virus. Studies show that warmer temperatures associated with this alteration of the environment can accelerate mosquito development and biting rates and the incubation of the disease within a mosquito.

Rising temperatures associated with climate change also appear to be lengthening the mosquito season in many parts of the United States. This means that people are at risk for exposure to the West Nile Virus for longer each year. In some cases, the risk for exposure begins earlier in the spring and extends into the fall.


Climate change is a global problem that is already beginning to affect the Earth in various ways. One of the most serious impacts is the way it is altering the prevalence and behavior of pests and diseases around the world. 

As the climate continues to change, it is important to be aware of the potential risks posed by these changes and take steps to protect ourselves and our environment.
