Planning to buy a home? Avoid these 12 cities in the US with major rat issues |
Rats are one of the most common pests in cities around the world. They do well in cities where there is a lot of food waste, underground tunnels, and close housing that gives them shelter and easy access to food. Rodents are hard to get rid of in big cities because they adapt quickly to living with people. If urban rats can find small openings, they can live in sewers, alleyways, subway tunnels, abandoned buildings, and even inside homes.Several pest control organisations track rodent activity to understand where infestations are most common. One of the most widely cited sources is the annual “Top 50 Rattiest Cities” report by pest control company Orkin, which ranks cities based on the number of residential rodent treatment services carried out during a specific period. According to the company, the rankings are compiled by analysing new rodent control services performed by technicians over 12 months.These service calls provide an indication of where residents report the highest levels of rat activity. According to the most recent data from Orkin, a number of major cities are always near the top of the list because they get a lot of complaints about rodents and requests for pest control.
12 cities you should avoid buying homes in if you can’t stand rats
1. Chicago: A long history of urban rat problems
Chicago has often been named one of the US cities with the most rats. In fact, the city held the top spot on Orkin’s “Rattiest Cities” list for ten consecutive years.Experts say Chicago’s dense neighbourhoods and large network of alleys create ideal hiding places for rodents. The city’s extensive underground infrastructure also allows rats to burrow and move between locations while searching for food.
2. Los Angeles: Warm climate supports rodent activity
Los Angeles has also ranked near the top of the rat activity list. In recent reports, the city even moved into the number one position in the ranking.Researchers say that the warm weather in the area lets rats stay active all year long. This, along with crowded cities and a big food service industry, makes it easy for rodents to live and grow.
3. New York City: High population and food waste attract rodents
New York City is another big city that always has a lot of rats. Orkin’s rankings show that the city has been in the top three for pest control for several years.The city’s large population produces large volumes of waste each day. Rats often search for food in garbage areas, subway tunnels, and building basements.
4. San Francisco: Dense urban neighbourhoods and older infrastructure
San Francisco is often one of the cities with the most rats. In some places, it can be hard to control rodents because of the old buildings, close-knit neighbourhoods, and busy food districts.Rodents often use cracks in building foundations and underground pipes as entry points.
5. Washington, D.C.: Frequent rodent complaints in urban areas
The US capital also appears frequently in rodent activity reports. Data from pest control shows that people in many parts of the city often ask for help with rodents.Urban parks, construction sites, and alleyways can provide spaces where rats build nests and search for food.
6. Denver: Growing city with rising rodent activity
Denver has appeared in the top rankings of rat activity in recent reports. Rapid urban growth and construction projects may disturb underground nests, causing rodents to move into residential areas.Pest control companies report frequent service calls related to rats in some neighbourhoods.
7. Philadelphia: Historic buildings provide shelter for rodents
Another city that often shows up on lists of places where rodents are active is Philadelphia. Rats can find places to nest in older buildings and neighbourhoods with a lot of people.City officials regularly run pest control programs to keep infestations down.
8. Detroit: High demand for rodent control services
Pest control reports have repeatedly put Detroit in the top ten cities for rat activity. Data from Orkin shows that the city continues to receive significant numbers of rodent treatment requests each year.Vacant buildings and ageing infrastructure in some areas can create conditions where rodents find shelter.
9. Baltimore: Ongoing urban rat management efforts
Baltimore also appears regularly in pest control rankings. Like many older cities, its dense housing and underground infrastructure that can create suitable habitats for rats.Local authorities often run rodent control programmes to address infestations.
10. Cleveland: Consistent rodent treatment requests
Cleveland is another city that shows high demand for pest control services related to rats. Treatment data suggests that rodent activity remains a concern in several neighbourhoods.Urban waste and abandoned buildings are often identified as contributing factors.
11. Minneapolis: Cold winters but persistent rodent activity
Minneapolis still shows up on the list of cities with the most rat activity, even though winters are colder there. Rats often stay alive by making nests in buildings, basements, and underground systems where the temperature stays higher.Rodent infestations in the area are a common reason for people to call pest control companies.
12. Boston: Dense historic districts and rodent habitats
Boston completes the list of cities that frequently appear in rodent activity reports. The city’s historic districts and compact neighbourhoods can provide shelter and food sources for rats.Rodent control efforts in Boston often focus on sanitation and waste management to limit food sources.
How these rankings are calculated
The cities mentioned above are based on pest control treatment data rather than direct rat population counts. According to Orkin, the ranking is calculated using:
- The number of residential rodent treatment services
- Customer service requests for pest control
- Data collected during a one-year period by technicians across the country
Cities with higher numbers of rodent treatment calls are placed higher in the ranking.
Why rats thrive in big cities
Scientists and pest control experts say several factors help rats survive in urban environments. These include:
- A lot of food waste
- Sewers and tunnels that go underground
- Places where buildings are being built or left behind
- A lot of people and housing structures are close together
Reports from The Guardian say that studies have also shown that warmer temperatures in cities may let rats breed for longer periods of time during the year, which can lead to more rats living in cities.
