With an anticipated rise in sightings of ticks, rodents, mosquitoes, and cockroaches due to projected warm weather trends, the National Pest Management Association shared its bi-annual Vector Sectors list, unveiling the top U.S. cities at heightened risk for increased vector pest pressure throughout the remainder of winter and into spring.

Included on the list is Los Angeles. The report stated: “Mosquito populations could continue to thrive well into the winter months if warmer temperatures and above-average rainfall persist as forecasted.”

The Centers for Disease Control and Prevention (CDC) notably reports a spike in disease epidemics from viruses spread by mosquitoes, including recent dengue outbreaks in many countries worldwide.

“With springtime and warm weather on the horizon, many Americans are itching to get outside,” says Dr. Jim Fredericks, senior vice president of public affairs for NPMA. "As pest experts, we're utilizing our Vector Sectors™ list to help consumers understand the connection between weather conditions and pest behavior and empowering them with tools to safeguard not just their homes but, crucially, their health."

In the past decade, the CDC reports not only showed an increase in the number of dangerous vector-borne diseases, such as dengue and Lyme disease, but also the geographic spread of the vectors.

“Some pests can leave more than an itchy bite mark,” says Dr. Jorge Parada, medical advisor for NPMA with a focus on infectious disease. “Vector pests can spread pathogens to humans through their bites, making prevention especially important to help reduce transmission of dangerous and potentially deadly diseases.”

Weather conditions and pests

Weather conditions can have a significant impact on pest behavior. Understanding the connection between weather conditions and pest behavior can help in developing effective pest management strategies.

Clark, California’s friendly pest, rodent, mosquito, and termite control expert, keeps an eye on weather conditions to help predict periods of increased pest activity. Its highly trained and licensed technicians know how to make correct treatment recommendations.

Temperature can affect the development, reproduction, and activity of pests. For example, many insects are more active in warm weather, leading to increased pest activity during summer months. On the other hand, some pests, like rodents, may seek shelter indoors during cold weather.

Humidity can also influence pest behavior. Some pests, like cockroaches, thrive in humid environments and may be more active in areas with high humidity levels. Other pests, such as certain types of ants, may be more active during periods of low humidity.

Rainfall can impact pest behavior in several ways. Heavy rainfall can flood underground burrows, forcing such pests as rodents to seek shelter elsewhere. Additionally, standing water left behind by rain can create breeding grounds for mosquitoes and other water-loving pests.

Seasonal changes, such as the transition from winter to spring, can also influence pest behavior. For example, as temperatures warm up in the spring, pests that have been dormant during winter months may become active again.
