Cockroaches thrive in NC’s warm, humid weather. Here’s how to keep them out of your home
It’s hot outside in North Carolina, which means you’re more likely to find a variety of pests trying to get into your home, including cockroaches.
“Cockroaches are a nocturnal pest that thrives in a warm and humid environment,” meaning summer weather in North Carolina gives them the perfect breeding ground, according to Triangle Pest Control.
While cockroaches don’t bite, they can carry diseases that can be harmful to humans, including Salmonella and poliomyelitis, the virus that causes polio, according to the Centers for Disease Control and Prevention.
Cockroaches are also a source of allergens, which can trigger respiratory illnesses like asthma, according to the American Lung Association.
Here’s why cockroaches enter your home, some signs to watch for and how to keep them out.
Why do cockroaches enter your home?
Cockroaches can get inside homes through any opening that is accessible to them, according to Kristin Dodd, the manager of Carolina Pest Management.
“You’ll see them come in through windows and doors that aren’t sealed properly, or through plumbing,” Dodd told The Charlotte Observer in June 2022. “It doesn’t take a large opening for them to get through.”
Once inside, cockroaches like to hide in dark, damp places including kitchens, bathrooms, and basements, Dodd said, adding that some roaches gravitate “anywhere that there’s food available,” like trash cans and dog bowls.
Signs of a cockroach infestation
