Landmark’s technicians are specially trained to control cockroach infestations at their source. We first employ chemical-free measures such as barriers, screens, sealant, door sweeps, insect traps, vacuuming, sanitation and the removal of food and harborage.
Landmark treats using targeted products tailored to attract roaches. Our modern techniques are informed by research on the way cockroaches feed to deliver active ingredients that eradicate infestations. The products that we use to kill cockroaches are the mildest products available, applied in the most targeted fashion, and used in the smallest effective dose.
Cockroaches enter buildings through deliveries, cracks and crevices, drains, potted plants, and employees’ handbags and lunches. Once inside, they subsist and breed on very little food from trash, crumbs beneath vending machines, and in kitchenettes and employee breakrooms.
Health Risks Posed by Cockroaches
Cockroaches pose numerous risks to human health. Contact with cockroaches should be avoided and their presence and eradication should be taken seriously. Health risks associated with cockroaches include:
- Cockroach excrement and shed skins contain allergens that can cause watery eyes, sneezing, and skin rashes. Allergens associated with roaches can worsen asthma and chronic lung diseases. Cockroaches have been found to be an exacerbating factor in some fatal asthma attacks.
- Pathogenic organisms are found on cockroaches and their feces. Cockroach-related pathogens cause food poisoning, vomiting, diarrhea, dysentery, and nausea.
- Because cockroaches breed in and walk across filthy areas including sewers, toilets, garbage, and waste, they deposit bacteria and germs from these areas on any surfaces they walk across including food preparation areas.
Different species of cockroach differ in their behavior, habits, and biology. Your Landmark professional will assess the infestation by properly identifying the infesting species.
The most common infesting cockroach species in Chicago and the surrounding suburbs are American, German, and Oriental cockroaches. These fast moving insects thrive by using their flat bodies to conceal themselves in tight, dark spaces. Prolific breeders, they seek out food, moisture, heat, and dark places conducive to hiding and breeding, and access structures by moving along cracks and crevices, pipes chases, and conduits.
The American cockroach, the largest of the common roaches, measures 1.5 inches in length and is reddish-brown in color. The adult American cockroach is easily distinguished by its large size, large folded wings, and pale-colored border at the top of its head. Nymphs are gray-brown in color. American cockroaches can live for more than a year and in that time a single cockroach can produce over 1,400 young.
The German cockroach is the species most often found infesting buildings in Illinois. This small, 0.5 inch, tan-colored roach is a prolific breeder and can appear in large numbers. Nymphs may appear darker than adults. The adult German cockroach is easily distinguished by two dark stripes on its head. They generally live less than one year, though a single adult female can produce over 350 young in her lifetime.
Measuring about 1 inch long, the Oriental cockroach can be distinguished by its shiny dark brown-black coloring. Sometimes referred to as a “waterbug,” this species of roach prefers a damp environment, often enters structures through sewer lines, and congregates in damp basements. The Oriental cockroach and can produce well over 100 young in its lifetime.
