If you’ve ever lived in an apartment building, you might be familiar with how quickly one tenant’s problem becomes everyone’s problem. One leaking pipe on the fourth floor becomes ceiling stains on the third, a ruined floor on the second (and you don’t even want to know what happens on the first floor).
Urban pests operate the same way. One person’s untreated bed bug or cockroach infestation can ripple through an entire building. Urban entomology is the field dedicated to understanding and managing these tiny tenants. It keeps our cities healthier, safer and far more livable than they’d be without it.
Below are seven reasons urban entomology matters today, especially as cities grow more crowded.
Urban entomology protects public health, both physically and emotionally, especially in places where people live close together.
Cockroaches trigger asthma. Mosquitoes spread diseases. Bed bugs cause stress and insomnia (not to mention how costly they can be to treat). In dense cities where these pests are most abundant, pests aren’t just a nuisance — they’re a public health risk.
Urban entomologists study how pests move, reproduce, spread allergens and transmit pathogens. Their insights guide hospitals, schools and public health agencies in reducing exposure, especially for people who face a higher risk, like:
Urban entomology also seeks to influence our decision on use of both cultural and chemical control. Especially for the latter, improper chemical use can both be wasteful and harmful to human health.
Pest problems don’t hit every neighborhood equally. Older buildings and overcrowded housing amplify infestations.
Urban entomology helps bridge this gap. It gives stakeholders — such as housing authorities and city planners — the data they need to design fair, effective solutions, like:
There is a common misconception that urban pests only seek lower-income housing. These opportunistic pests will infest homes of any income level and thrive, when given the chance. It may simply be more apparent in lower income housing, where families cannot readily afford treatment.
Urban entomology also matters because pests show up where people gather and depend on essential services. They’re not taking up residence in one apartment and saying, “This is nice. Let’s just stay here.” Any opening, such as ventilation tubes, electrical outlets, and cracks between walls are means for these pests to spread elsewhere.
Urban insects also disrupt:
You might not visit a hospital, hotels, or a restaurant often, but others in the city frequent these locations every day, and urban pests can cause serious problems in a hurry.
For instance, a single introduction of bed bugs in a homeless shelter can spread to dozens of beds within days. Cockroaches can spread to multiple apartment buildings when infested furniture are moved around. Lice can spread among people by sharing products like the hair brush.
Thankfully, urban entomologists help these high-traffic environments stay safe by:
These tools allow us to detect urban pest problems early, which makes management more efficient and effective. They also provide information important for management decision making, such as where in a building to apply treatment.
For decades, urban pest control relied heavily on widespread chemical spraying. Effective? Sure. But also disruptive to ecosystems, human health and species pest control technicians didn’t mean to target.
Today, many cities and agencies follow integrated pest management, a more strategic approach that relies on:
Urban entomologists are the masterminds behind these plans. Their research helps determine:
Even after we have determined these factors, there are still remaining nuisance to urban pest management:
Ultimately, we seek to reduce chemical exposure while improving treatment effectiveness. Children and pets may unknowingly reach into a place that has been treated, so extra caution is warranted. Thus, for homeowners, tenants, and urban entomologists, education is a key component to a successful management.
As temperatures continue to rise, pests are behaving differently. Mosquito seasons are lengthening. Termites and mosquitoes are expanding their range. Some insects are producing more generations per year, boosting population numbers in urban spaces.
Urban entomologists monitor how climate change alters pest distribution, helping cities prepare instead of simply reacting. This work influences:
City officials can’t control the weather, but with the right entomological data, they can plan for and control how they respond to it. This is especially important after an environmental disaster, such as hurricanes. These weather events will spread waste and debris that contain pests, and urban pests can quickly grow out of control. For example, after the Fukushima earthquake in Japan, locals have witnessed a river of fly larvae marching through the streets!
If a city is the sum of its buildings, pests are among the small cracks that weaken its framework. Left unchecked, they can turn into major issues that threaten stability. Managed properly, pests remain minor inconveniences rather than building (or neighborhood-wide) crises.
Urban entomology supports resilience by helping municipalities develop long-term strategies that keep pests — and their consequences — under control. That includes everything from rodent-proofing waste systems to designing pest-resistant landscaping around schools and parks.
Urban entomologists do more than identify and remove unwanted insects from city buildings. This branch of entomology can lay the foundation for careers in other areas, like:
It’s a field where science meets strategy, and where professionals can see the results of their work in healthier homes, safer classrooms and stronger city systems.
If the idea of solving building-wide pest problems before they spread appeals to you, urban entomology could be your next step.

Picture this: You’ve been craving those mouthwatering appetizers at your favorite weekend spot all afternoon. You finally arrive, eager to dig in, only to find the restaurant’s closed. Odd, right? It was open just last week.
Upon closer inspection, you spot a notice slapped on the door—a failed health inspection. The culprit? A significant pest infestation.
Now, who’s more frustrated: you, or the restaurant owner? Hard to say. Either way, this restaurant has clearly missed the mark on one of the key aspects of maintaining a safe and welcoming environment: pest management.
But what if the owner was doing everything right? What if they were taking all the right precautions to keep pests under control, but the unique challenges of urban pest management simply proved too much? Today, we’ll dive into the specific obstacles faced by homeowners, business owners and even municipalities when it comes to managing pests in an urban setting.
Before diving into the challenges of urban pest management, it’s helpful to know which types of creatures frequently invade city-dwelling spaces. Common urban pests include:
In 2021, of the 124 million housing units nationwide, 14 million households reported seeing cockroaches in their homes over the past year. Meanwhile, 14.8 million households dealt with mice or rats. Pest problems are particularly common in the Southern states, where the warm, humid climate creates an ideal environment for resilient pests like cockroaches, termites and rodents to thrive.
There are several reasons that almost 9% of households in the U.S. have dealt with pests in their homes — and that doesn’t even account for the 90% of businesses that have experienced at least one pest infestation in the past five years.
Some common denominators that make it challenging to rid urban environments of pests include:
It’s no surprise that cities are more densely populated than rural communities, as they house more people in a limited amount of space. In homes like apartments and high-rise condos, pests don’t have to wait for open windows to spread from property to property. Instead, they travel undetected through shared walls, ventilation systems and utility lines.
Once pests infest multiple units, managing them can become a significant challenge. Traditional extermination efforts that target one unit are often ineffective, as pests can remain in neighboring homes and easily reinvade. The most effective solution is a coordinated pest management strategy applied across entire buildings, ensuring all pests are eradicated simultaneously.
Projections from the Congressional Budget Office estimate that housing starts will reach approximately 1.6 million each year over the next decade. While this signals growth in new housing, it doesn’t change the reality that much of the existing residential and commercial real estate is decades old. Older buildings are particularly susceptible to infrastructure problems, such as cracks, gaps and crevices, which serve as convenient entry points and nesting areas for pests.
These structural vulnerabilities make pest control an ongoing battle in urban settings. Without addressing these issues at the source — through repairs and preventative maintenance — pests will continue to find ways to thrive, regardless of extermination efforts.
City living comes with undeniable perks: vibrant culture, endless entertainment options and convenient amenities. However, what urban environments gain in energy and excitement, they often lack in space. This scarcity poses several challenges for pest management:
There may not be a one-size-fits-all solution to managing pests in urban areas, but there are practical steps that both pest management professionals and residents can take to minimize infestations:
From the bustling streets of New York City to the serene cabins of the Blue Ridge Mountains, pests are an inevitable part of life — but that doesn’t mean they can’t be managed.

When you sit at the dinner table enjoying a colorful salad full of fresh produce, are you considering the impact that insects play in the loss of global crop production? If you’re not in pest management, probably not. But if you are, the numbers are staggering.
Approximately 20% to 40% of crops produced around the world are lost each year due to pests. In addition, invasive insects cost the global economy an estimated $70 billion annually. And because climate change continues to slowly increase the earth’s temperature and play with its precipitation levels like a child with a water hose, we must ask: If climate change has the potential to increase the number of pests globally, will that have an impact on pest management in the future?
Put simply, yes. Join us as we explain everything you need to know about insects and climate change and the effect they may have on the pest management industry.
Climate change refers to long-term changes in the earth’s weather patterns and temperatures. While slight shifts in temperature or precipitation levels are natural, human activities (like our global use of fossil fuels) have expedited the drastic effects of climate change. Fossil fuels account for 75% of global greenhouse emissions, which are responsible for trapping the sun’s heat in the atmosphere and increasing the earth’s natural temperatures.
These changes are expected to lead to a variety of problems in the future, including:
One of the causes of a potential food shortage could be the impact that climate change has on insects. Insects like the Mexican fruit fly and Asian citrus psyllid are responsible for the destruction of an array of fruits and vegetables. Imagine if those pests multiplied at a faster rate due to the rising temperatures, consuming and ruining an even higher number of crops. The result? Fewer crops available for global consumption and a lack of produce to meet the needs of consumers.
Many insects are sensitive to changes in temperature and would react favorably to even the slightest temperature increase. With the global temperature expected to increase by 1.8 degrees Celsius (approximately four degrees Fahrenheit) over the next century, some species may begin to reproduce more quickly. This could eventually lead to insects destroying even more crops by way of:
How will a potential increase in crop-consuming and disease-spreading pests affect the pest management industry? That will depend on how quickly each region can adapt to recurring and new species of pests discovering their crops. Some potential pest management strategies include:
IPM uses science-based decisions to identify and manage pests. By integrating new practices, farmers are more likely to generate a higher yield of crops each season. For example, since some species of insects are likely to multiply faster as temperatures increase, an integrated pest manager could lower the current treatment threshold so that crops are treated in a more timely manner. It may also be beneficial to plant a variety of crops at different times of the year to minimize exposure to a growing number of pests.
One of the most effective ways of determining climate change’s impact on insects is by recording data in real-time. Long-term monitoring could provide the first round of analytics regarding changes in geographical distribution and transmission of plant disease brought about by pests.
With consistent monitoring, experts in the pest management industry can use predictive tools to determine the likelihood of some species of insects creating an extra generation each year. They could also use collected data to calculate whether pests are likely to migrate to new locations based on the level of temperature change.
With the number of insects potentially on the rise, the need for experts in the pest management industry is also likely to grow.
