Pest outbreak alert in US: Is your area the next hotspot for disease-carrying bugs?

The change from winter to spring is bringing an increased risk of disease-spreading pests across several US cities.

The National Pest Management Association (NPMA) has said that areas with exceptionally warm or wet winters may see an increase in pests such as ticks, mosquitoes, cockroaches and rodents, which are carriers of Lyme disease, West Nile virus and hantavirus.

Weather changes and rising pest populations

Unusual weather events, such as unexpected snowfall in the South and long warm weather elsewhere, have created ideal conditions for pest proliferation. Warmer winters allow rodent populations to survive in greater numbers, while wet conditions encourage mosquitoes and ticks.


Jim Fredericks, senior vice president of public affairs for NPMA, explained that ticks become active when temperatures exceed 50 degrees Fahrenheit, making an early spring particularly concerning.

Climate change is also expanding the range of many pests. Rising temperatures are pushing ticks and other species into new territories, increasing the risk of disease transmission. Extreme weather events, such as heavy snow followed by rapid warming, are forcing rodents indoors, raising human exposure to these pests.

Cities facing pest threats

Several US cities have been identified as hotspots for increased pest activity due to recent weather trends:

Boston: Harsh winter conditions have driven rodents indoors, and an early warm spring could increase tick activity.

Cleveland: Soggy winter conditions may lead to a rise in cockroaches and ticks.

Denver: Heavy snowfall is likely to force mice indoors.

Grand Rapids, MI: A snowy season may push more rats and mice indoors, while heavy rain could lead to tick growth.

Louisville, KY: Extreme cold has led to increased indoor rodent activity, and a warm spring could cause ticks to increase.

San Antonio: A warm winter has allowed mosquitoes and cockroaches to remain active.

Washington, D.C.: A volatile winter has contributed to increased rodent activity, and an early spring may lead to a rise in ticks.

Florida: The humid climate allows mosquitoes to thrive year-round.

Efforts to combat mosquito-borne diseases

Florida has long struggled with mosquito-related illnesses, with outbreaks of dengue fever and Zika virus in recent years. Scientists, including Ryan Carney from the University of South Florida, are using AI and citizen science projects to track mosquito populations and prevent disease outbreaks.

FAQs

1. Why are disease-spreading pests increasing in some US cities?
The rise in pests is linked to unusual weather patterns, including warmer winters and excessive moisture, which create favourable conditions for their survival.


2. Which cities are most at risk for increased pest activity?
Cities such as Boston, Cleveland, Denver and Washington, D.C., are expected to see a rise in pest-related health threats due to extreme weather patterns.
