They Carry Diseases Cockroaches are known to carry at least 30 different types of bacteria. According to the WHO, these diseases include typhoid fever, cholera, dysentery, and diarrhea. Breathing in the air infested by cockroaches is enough to inhale any of the bacteria they carry.
They Breed in Filth
Many people suggest that a cockroach is a sign of a filthy home, but cockroaches can breed in even the cleanest of homes, provided that there's an area that's ideal for their mating and living habits.
Cockroaches in the home environment are a health hazard not only because of the risks posed by cockroach antigens to asthma sufferers, but also because they can carry disease-causing germs and because some of the methods traditionally used to eliminate them cause additional health hazards.
Finding roaches is not a sign that your house is dirty. Even if you clean regularly and maintain a tidy home, cockroaches can usually find food and water without much trouble. This allows them to thrive in many environments.
Even if you tidy up your kitchen and dining area after each meal, it still might not be enough to prevent a roach from foraging through your home. Roaches often detect crumbs that have been missed under the refrigerator and microwave and food that hasn't been adequately sealed in the pantry.
Cockroaches are repelled by the smells of peppermint, eucalyptus, lavender, citronella, and cedarwood oils. These scents can be used as natural deterrents to keep them away from your home.
Cockroaches can both cause and aggravate respiratory problems. The saliva that cockroaches continually secrete contains hundreds of allergens that can cause rashes, sneezing, and itchy, watery eyes. Cockroach infestations can also aggravate existing allergy symptoms.
Citrus is one of the scents cockroaches are most known to hate, notably lemon and orange. Keeping a dish of lemon juice on your kitchen counter can deter these pests, as well as placing lemon peels around the home to discourage cockroaches from coming out of hiding.
Leaving the light on doesn't deter cockroaches effectively because they can navigate in low-light conditions. While they're mostly active at night, they may still come out in search of food or water. During the day, cockroaches hide in dark areas not directly exposed to light.
While dirty environments certainly attract roaches, even clean homes can fall victim to roach infestations.
Most likely to occur around the mouth, hands and fingers, cockroach bites look like small red, inflamed bumps that can be itchy. If you suspect that you have been bitten by a cockroach, wash the area with warm soap water to clean it and ice with a cold compress to bring down the inflammation.
Yet given what we know today, logically it does not make sense to fear cockroaches. Unlike mosquitoes, ticks or fleas, roaches aren't disease vectors, and they do not feed directly on our blood, skin or fluids. We don't go screaming when we see a mosquito, even though they are the world's deadliest animal.
While cockroaches can crawl on humans at night, it is relatively rare. Cockroaches are more interested in finding food and shelter than in seeking human contact. However, if you have a severe infestation or roaches are attracted to food or crumbs in your bed, they may enter your sleeping area.
What causes roaches in houses and apartments? What attracts roaches to a clean house primarily consists of their basic needs: food, water, and shelter, although they are usually brought into houses and apartments on other items, such as luggage or clothing.
Myth #3: They can see me coming…
True: Why yes, they can. Cockroaches can see humans, and that is why they tend to run in fear when we are in their line of sight. The eye of the cockroach is like a compound lens, made of over 2,000 mini lenses that are photoreceptors and allow them to see in complete darkness.
Tenants should report any signs of cockroaches to their landlord right away. Quick action can prevent a small problem from becoming a big one. Landlords should respond promptly to these reports and take the necessary steps to address the issue.
Cockroaches are nocturnal and prefer to stay hidden in cracks and crevices during the day, which means if you see one, there's a good chance it's not alone. Cockroaches can squeeze into the smallest spaces and multiply quickly, especially German roaches, producing hundreds of offspring in a year.
Seeing a cockroach crawl across a bed isn't unusual if the insects are already making a home in your bedroom or a nearby bathroom.
In addition to being unsightly pests, cockroaches can also be a health hazard. When an infestation occurs, the presence of cockroaches in large numbers increases the dangers presented by these insects.
Ultrasonic Cockroach Repellents
There are electronic devices that emit high-frequency sound waves that act as cockroach repellents. These devices emit sound in the 22-65 Khz range which is inaudible to humans but can be detected by certain pests, including cockroaches.
Cockroaches are blessed with an amazing sense of smell. This is what they use when seeking food and mate but at the same time, this is also their weakness. A cockroach's sense of smell can be used to get rid of them.
