Four Signs You Have a Cockroach Infestation

roaches

Cockroaches are some of the most unsightly pests one can see in their house. They are also capable of spreading disease-causing pathogens, triggering allergic reactions and exacerbating asthma. Cockroaches contaminate the surfaces upon which they walk and the food with which they come into contact. For these reasons, it’s important to know how to tell if you have cockroaches, what species of cockroaches you may see in your house, and how to prevent or eliminate them. 

F&W Pest Control has been serving Massachusetts for over 75 years, so you can rest assured that we know our local cockroaches and how to best treat them! Check out our cockroach guide below. If you still have questions, give us a call at 508-384-6400 and we will be glad to help you!

The 3 Most Common Cockroaches in Massachusetts

Scientists estimate that cockroaches have been on this planet for more than 300 million years. During that time, approximately 4,600 species of cockroaches have developed, but only three species are commonly found inside homes and businesses in the Massachusetts area. 

1. American cockroach 

American cockroaches are the largest of the species, measuring anywhere from 1-3/8 to 2 inches long. They’re reddish-brown with a pale mask-like pattern on its back, and they have wings and can fly (only short distances). They are commonly found in residences and commercial buildings, such as restaurants and stores—anywhere with storage to hide in. The development time for an American cockroach is anywhere from six months to two years. About 10 egg capsules are produced per cycle, each hatching around 14-16 eggs. 

2. German cockroach

German cockroaches are most often found in tight, closed spaces. Since they’re smaller—only ½ inch to ¾ inches long—they can hide easier than other species of cockroaches. They are tan and brown, and they have wings but cannot fly. They are the fastest species to reproduce: development time from egg to adult is only four months, and 15 to 50 nymphs are hatched in a single cycle.

3. Oriental cockroach

The Oriental cockroach, with a maximum length of about an inch, is shiny and dark brown in color. These roaches are more commonly known as “water bugs” as they are found in dark and wet places, such as basements, sewers, bathrooms, and under sinks. They have wings but cannot fly. Each egg capsule (ootheca) contains up to 16 eggs, and females reproduce about eight times during their adult lifetime. Oriental cockroaches only live for about six months.

To prevent all species of cockroaches, always practice good sanitation and have regularly scheduled pest control complete with a roach exclusion.

4 Signs of a Cockroach Infestation

The sooner a cockroach infestation is eradicated, the easier it will be to obtain complete control. However, because most species of cockroaches are nocturnal and tend to be secretive, a serious infestation can occur before you ever catch sight of a live roach. If you know the four primary signs that you have a cockroach infestation, you can take action sooner and eliminate these unsightly pests.

1. You find their droppings

Roaches have surprisingly voracious appetites and will eat virtually anything, including human food, pet food, garbage, and dead skin cells. As a result, they tend to leave droppings wherever they go. The type of roach determines the appearance of the droppings, but most roach droppings resemble coffee grounds or specks of black pepper. If the droppings are found in many different locations, you may have a large infestation. If the droppings tend to be found in one area, you should take steps to eliminate any sources of nearby water and food to help control the roach population.

You can find roach droppings:

  • On counters and floors
  • Behind and underneath kitchen appliances or the washer and dryer
  • In the corners of shelves in the kitchen and bathroom cabinets
  • Inside the pantry

2. You find their egg cases

Roaches are prolific breeders, but their reproduction method can make it easier to find evidence that they have invaded. Roach eggs are contained inside egg cases that are known as oothecae. Each ootheca can contain 10 to 50 eggs. Some species of roaches keep their oothecae attached until just hours before the eggs hatch, but other species will attach an ootheca in a sheltered space several days before hatching occurs. Once the eggs hatch, the ootheca — which is a brown, oblong, nearly translucent casing — is left behind. 

Where to find empty or full oothecae:

  • In books
  • Inside cabinets
  • Behind furniture
  • In any dark, protected, tight areas
  • On counters, if the infestation is severe

3. You smell a musty, pungent, oily odor

A single German cockroach can produce this smell, but most people will not notice an odor until the roach population is quite high. 

Why do roaches leave a smell?

  • Secreted pheromones 
  • Odor trails 
  • Droppings
  • Dead, decomposing roaches

4. You see a live roach or find a dead one

Most people only see live roaches at night—they enter a dark kitchen or bathroom, turn on the light, and see roaches run for cover. However, if the roach population is high, you may see roaches during the day as well. A lack of resources and overcrowding can force roaches to migrate during daylight hours if they want to survive. Finding a dead roach is also an indication of an infestation, especially if it is found in areas where droppings or egg casings have been found.

Cockroach FAQs

What do cockroaches look like?

The cockroach has an oval somewhat flattened head partially concealed by the pronotum and with the mouth pointing backward between the fore coxa. The antennae are long and thin and inserted below the middle of the eyes, the mouthparts are adapted for biting, chewing, and licking while the compound eyes are usually large and irregularly hemispherical being wider near the vertex (the top of the front of the head). The forewings (tegmina) are usually hardened and often opaque, while the hind wings are membranous. The legs are almost equal in length and depressed beneath the body and the abdomen has ten segments, only 7 or 8 being visible from above.

What do cockroaches eat?

Cockroaches will eat almost anything: left-over human food, wood, leather, cigarette butts, tooth paste, milk, sugary materials, coffee grinds, glue, soap, feces, fabric, shoes, paint, the glue on the back of the wallpaper, human hair, fingernails, etc.

How do you prevent cockroaches?

Controlling the availability of food, water, and hiding places can manage cockroach populations. Poor sanitation that is contributing to a cockroach problem should be corrected. Food and water should not be left out overnight and should be stored so as to deny access by the roaches. 

Structural modifications that will deny cockroaches access to hiding places should be undertaken. In multiple unit dwellings, this should include modifications to prevent the free movement of roaches between dwellings.

What Do I Do If I See Cockroaches In My House?

Although there are other signs of a roach infestation, most of them require a trained professional to read the evidence. The four signs listed are the most common signs that are relatively easy for an untrained person to recognize. Because cockroaches can trigger breathing problems or contaminate food, it’s imperative to contact the professionals at F&W Pest Control for safe, effective treatments as soon as you think you may have an infestation.
