Cockroaches are nocturnal insects that prefer to live and feed in dark conditions. When a cockroach is seen during daylight, it is a likely sign of infestation. Cockroaches love to hide, and prefer dark, moist areas for hiding out and breeding. A cockroach’s preferred locale is behind refrigerators, sinks and stoves. They are also known to hide under floor drains and inside appliances. Cockroaches can be tricky to find because they can flatten their bodies to fit in narrow areas, which is why they can be found under rubber mats, behind wallpaper and in narrow cracks and crevices.

    The untrained eye may not easily identify the signs and symptoms of a cockroach infestation. The expert technicians at Mariners Pest Control have been trained and certified to identify a cockroach infestation. Signs of a cockroach infestation include:

    • Cockroach feces resembling black pepper, coffee grounds or cylindrical droppings
    • Strong oily or musty odor
    • Dead or alive cockroach
    • Oval-shaped cockroach egg cases, known as oothecae


    If a cockroach infestation is identified during inspection, a cockroach treatment plan will be discussed to terminate your cockroach infestation. Not only are cockroaches unsightly, they also have many negative consequences for human health. Proteins, called allergens, found in cockroach feces, cockroach saliva, and cockroach body parts can cause allergic reactions or trigger asthma symptoms in children and adults. Cockroaches can also passively transport microbes on their body surfaces including pathogens dangerous to humans. Cockroaches have been pinpointed in the spread of many kinds of bacteria, including E. coli and Salmonella, parasitic works and other pathogens. Cockroach treatment and extermination will include a combination of external and internal home insecticide treatment, as well as barrier exclusion and sanitation methods. Preventing cockroaches from entering the home in the first place, as well as having a clean and sanitary home, will make the environment less inviting for cockroaches to move in. Cockroach treatment is usually followed up with a quarterly cockroach prevention treatment to the perimeter of your home.

    Cockroach allergens (substances that cause allergy symptoms) come from different parts of the cockroach. These allergens also can cause asthma!

    How long can a cockroach live without food or water?
    American cockroaches have been known to live for up to three months without food and one month without water.
    I opened my refrigerator and found a cockroach. I don’t understand how it got there. Where do you think it came from?
    The likely answer to this question is that a food item that you purchased contained a hitchhiking cockroach. While this may be an isolated intruder, it is better to play it safe and assume that there is more than one. The best recommendation would be to have a cockroach inspection performed by a professional pest control technician, in which they will evaluate your home for an infestation and if needed a treatment plan.
    I just had my home treated for a cockroach infestation. How do I prevent the cockroaches from coming back?
    It is recommended that you store all food in air-tight containers or in the refrigerator. Never leave food, crumbs, or trash uncovered in your home to avoid re-infestation. It is also recommended that you perform regular home inspection and maintenance to ensure that you do not have any leaky faucets or drains in order to eliminate a water source for cockroaches.
    Can I treat this cockroach problem on my own?

    Over-the-counter insecticides are typically ineffective with pest control in general, especially cockroaches. Since cockroaches can be hard to find, that makes them difficult for the average person to treat. A professional pest control technician should perform a home inspection to determine the scope of the cockroach infestation. Upon completion of the cockroach inspection, your pest control professional will recommend a treatment plan to exterminate your cockroach infestation and prevent a future infestation.
