Hidden Horrors: Signs of a Cockroach Infestation
Cockroaches are one of the last pests anyone wants to see at home. They’re unsettling to find, and more importantly, they can pose real health risks. These insects carry bacteria and pathogens that spread disease, and their droppings, saliva, and shed skins can trigger allergies or worsen asthma. They contaminate food and surfaces as they move, leaving your household vulnerable to health problems.
That’s why it helps to know how to spot the signs of a cockroach infestation early, understand the species you’re most likely to encounter in Massachusetts, and learn what you can do to keep them out.

The 3 Most Common Cockroaches in Massachusetts
Cockroaches have been around for hundreds of millions of years, with more than 4,000 species worldwide. Thankfully, only a handful ever invade homes in Massachusetts. Here are the three you’re most likely to encounter.
1. American cockroach
The American cockroach is the largest of the group, growing up to two inches long. Reddish-brown in color, it has a pale, mask-like marking on its back. While they can fly short distances, they’re more often seen running quickly across walls and floors. American cockroaches are common in restaurants, warehouses, and grocery stores, but they’ll also infest homes with plenty of storage or clutter to hide in. Each female produces egg capsules that hold 14–16 eggs, which means populations can build up quickly.
2. German cockroach
Smaller but far more prolific, the German cockroach measures only about half an inch long. These tan-brown roaches are excellent at hiding, especially in kitchens and bathrooms. They don’t fly, but they reproduce at an alarming rate: one female can produce up to 50 offspring in just a few months. This rapid breeding makes German cockroaches one of the most common and toughest pests to control in homes.
3. Oriental cockroach
Often called “water bugs,” Oriental cockroaches are dark brown and shiny, reaching about an inch in length. They prefer damp, cool spaces like basements, bathrooms, and sewers. Even though their adult lifespan is only about six months, they reproduce enough to spread quickly in the right conditions. Because they thrive in moisture, Oriental cockroaches can become a recurring problem if plumbing leaks or humidity aren’t addressed.
Prevention tip: No matter the species, good sanitation and routine pest control are the best defenses against cockroaches in your home.

Top 8 Signs of a Cockroach Infestation
Cockroaches are mostly nocturnal and do a good job of staying out of sight. That means infestations can grow severe before you ever spot one crawling across the floor. By watching for these common warning signs, you can catch the problem early.
1. Droppings
Cockroach droppings look like black pepper flakes or coffee grounds. You might see them behind appliances, inside cabinets, or along pantry shelves, which can quickly become a hazard for your health and food. The more droppings you find, the larger the infestation is likely to be.
2. Egg Cases
Roach egg cases, called oothecae, are small brown capsules that may contain anywhere from 10 to 50 eggs, depending on the species. You might spot them behind furniture, in dark cabinets, or tucked into tight spaces.
3. Odor
A musty, unpleasant odor is a strong clue of a growing infestation. Roaches release pheromones and leave behind scent trails that worsen as the population increases.
4. Live or Dead Cockroaches
Seeing a cockroach during the day often means the population is overcrowded and struggling to find resources. Dead roaches found alongside droppings or egg cases are also clear indicators of activity.
5. Furniture Damage
Cockroaches don’t limit themselves to food. They’ll also chew on wallpaper paste, book bindings, leather, and even fabric. Damage to furniture or walls could point to a hidden infestation.
6. Shedded Skin
Before reaching adulthood, cockroaches molt multiple times. These shed exoskeletons are often left behind near nesting areas and can trigger allergies if inhaled.
7. Smear Marks
In damp spaces, roaches leave dark smear marks as they crawl through their droppings. You’ll usually find these stains in areas with high roach traffic.
8. Allergy Symptoms
If you or your family members experience sudden sneezing, coughing, itchy eyes, or unexplained rashes, cockroach allergens may be the cause.

Cockroach FAQs
What Do Cockroaches Look Like?
Cockroaches have flat, oval bodies with long antennae and spiny legs. Most species in Massachusetts are brown to dark reddish-brown and vary in size from ½ inch to 2 inches long.
What Do Cockroaches Eat?
Cockroaches are scavengers and will eat nearly anything, including leftover food, pet food, cardboard, glue, leather, toothpaste, soap, fabric, and even hair or fingernails.
How Do You Prevent Cockroaches?
Reduce food, water, and hiding places. Store food in sealed containers, fix leaks promptly, clean crumbs and grease, and remove clutter. Sealing cracks and gaps can help keep roaches from moving between units in apartments or condos.

Don’t wait, because cockroaches reproduce quickly, and a small problem can escalate fast. Contact a licensed pest control company for a professional inspection and safe, effective treatments.
