Does Climate Change Cause More Pests in Your Home?
As the climate changes, this will inevitably affect our environment and how we live. One aspect of this, that is often discussed is how it could lead to increased pests and diseases. As the climate changes, we see more pests in our homes. In addition, bugs that we usually find in warmer climates are now making their way up north, bringing new diseases that can make us sick. In this post, we’ll discuss the link between climate change and pest populations and what you can do to keep them under control.
The Effect of Climate Change on Pest Population
Many insects are responding to the changing environment due to climate change. These changes include the distribution, demography, and life history of insects and pests. These changes can impact humans through an increased spread of pests and diseases on important crops.
Following are a few notable effects of climate change on insect pest scenarios, and pest population dynamics.
Expansion of Geographic Ranges
Insects are capable of moving long distances in search of more favorable environments. Climate change is, therefore, likely to cause the geographic ranges of many pests to expand. This could lead to introducing new pests to new areas, and increasing the range of existing pests.
Increased Abundance and/or Density
Warming temperatures can lead to an increase in the number of generations that a pest can have in a single year. This could result in a population explosion and a corresponding increase in the damage they cause.
Altered Phenology
Climate change can affect the timing of key life cycle events such as egg hatch, pupation, and adult emergence. This can result in a mismatch between the pest and its natural enemies and the plants it feeds on. For example, if a crop is flowering earlier than usual, pests that normally only feed on the pollen may start to feed on the developing fruit instead.
Increased Tolerance to Pesticides
Pests that pesticides have previously controlled may develop resistance to them due to natural selection. This could lead to an increase in the use of more toxic pesticides and the development of new pests resistant to all known pesticides.
What does this mean for us? More pests mean more chances of disease transmission. Insects can carry a variety of diseases, some of which are deadly to humans. As their populations increase, so does our risk of exposure to these diseases. Additionally, more pests can lead to more property damage. Insects like termites and carpenter ants can cause serious damage to homes and other structures.
How Can Pests Enter Homes During Climate Change?
Pests are said to be disturbed by the change in the climate. That’s why they often search for food and water, which can be a source of survival. With the temperature change, they can also move to different areas or places where the temperature is moderate for them. Climate change can make it easier for pests to enter our homes in a few different ways:
As the weather outside changes, so does the temperature inside our homes. This can cause Expansion and contraction of building materials, which can create cracks and gaps that pests can use to enter.
Homes have vents and openings to let fresh air in and keep pests out. However, if these vents are not properly sealed or screened, they can provide an easy way for pests to get inside.
Doors and windows are another common entry point for pests. If they are not properly sealed, gaps around them can allow pests to enter. Additionally, pests can easily wander in if doors are left open for extended periods.
Storms and floods can damage homes and create openings that pests can use to get inside. Also, storms can dislodge trees and other debris, providing hiding places for pests.
What Can You do to Prevent Pests From Entering Your Home?
It’s never fun to find pests in your home. Not only are they a nuisance, but they can also cause serious damage to your property. Fortunately, there are a few simple steps you can take to prevent pests from entering your home in the first place.
- Inspect Your Home Regularly: Be on the lookout for cracks, gaps, and other openings that pests could use to get inside. Regularly check doors and windows to make sure they are properly sealed.
- Repair Any Damage: If you find any damage to your home, repair it as soon as possible. This will help to prevent pests from getting inside.
- Keep Your Home Clean: Pests are attracted to food and other types of debris. Regularly cleaning your home will help to keep pests away.
- Store Food Properly: Make sure to store all food in airtight containers. This will help to prevent pests from getting to it.
- Call a Professional: If you find that your home is infested with pests, call a professional for help. They will be able to safely and effectively remove the pests from your home.
