Cockroaches might wander around our ears looking for some food. Roaches are attracted by the smell coming out from our ears. Its smell is like fermented bread, or beer, or cheese. Our own earwax release a similar kind of scent that woos the roaches.
You might be better off asking yourself what doesn't attract cockroaches, and there might be a few things. But the list of what draws them in is long. The three primary things cockroaches seek are food, water and shelter. That makes humans an ideal companion for them, because you are bound to have all three.
If a roach crawls on you while you're sleeping, it may attempt to feed on dead skin in your eyelashes, eyebrows, or around your lips. While doing this, it could bite you. If it does, you're likely to know it, as dirty cockroaches immediately introduce bacteria into the wounds they cause.
And just like cheese, our earwax radiates these cockroach-wooing chemicals as well. “The smell that emanates from the ear is attractive to the cockroach,” Schal tells The Verge. The problem is that once the roach crawls inside the ear, it's likely to get stuck.
Yes, killing a cockroach can attract more to the area! There is an acid released by cockroaches when they die that can be smelled from a distance and attracts more of them to the area.
Squashing a cockroach can spread disease
Indeed, salmonella, staphylococcus and streptococcus are some of the illnesses that cockroaches can cause, in addition to dysentery, diarrhoea, cholera and typhoid fever.
The World Health Organisation (WHO) has revealed that crushing a cockroach releases a harmful bacterium into the environment. The bacteria can cause asthma attacks, as well as allergies when inhaled. It may sound rare but it is actually more common that we realise.
If you have long sheets that make contact with your floor while you are getting some shut-eye, cockroaches will effortlessly climb and reach the bed in seconds. You need to fix this situation because it can become a serious problem for you if you don't.
Citrus. You may love the smell of fresh citrus, but cockroaches hate the scent. That means you can use citrus scented cleaners in your kitchen and bathroom to chase any lingering roaches away. You can also keep a few citrus peels around your home in strategic places.

If you touch a cockroach, you risk becoming infected with some serious diseases, including bacteria that cause dysentery. According to the World Health Organization, cockroaches commonly transmit these diseases to humans: Salmonellosis. Typhoid Fever.
It's a fact that cockroaches are afraid of humans and other mammals or animals that are bigger than them. They see us as predators and that fear triggers their instinct to scatter away. However, they dislike strong and distinctive scents such as citrus, peppermint, lavender and vinegar.
Cockroaches are repulsive and embarrassing to most people simply by their presence. They may contaminate food, kitchen utensils, and other household items, and they leave an unpleasant odor.
Cockroaches are drawn to all kinds of things you might find in your laundry room: Dirty clothes often have remnants of food, sugary drinks, sweet-smelling perfumes, or even dried skin on them, which can attract cockroaches. Body odors can also attract cockroaches, even when we can't smell them ourselves.
Baking Soda and Sugar Mixture
Mix a pinch of sugar with some baking soda in a bowl and leave it for the cockroaches. Attracted to the food source (the sugar), the roaches will ingest the poison (the baking soda) and die. It's safe and efficient, but make sure you clean up any dead roaches as soon as possible.
Mint. For best results, mix mint oil and water in a spray bottle and spritz anywhere bugs can enter your home. Mint, such as peppermint oil, contains a compound called menthone that can kill cockroaches. And since menthone is what gives the oil its smell, it works great as a deterrent.
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. There are smells they can not stand so we can use this to shoo them away from our homes.
Sugar is by far the most attractive substance to a cockroach. They love sugar and can smell it from anywhere. This means you'll want to keep your sugar containers, fruits, and other sweeteners sealed in air-tight containers that are up off the floor.
Borax is a readily-available laundry product that's excellent for killing roaches. For best results, combine equal parts borax and white table sugar. Dust the mixture any place you've seen roach activity. When the roaches consume the borax, it will dehydrate them and kill them rapidly.
Cockroach bite marks may be between 1–4 millimeters in diameter. Based on the physiology of their mouthparts, cockroach bites may appear as red, raised bumps on the skin—similar to bed bug bites or mosquito bites but slightly larger.
Breadcrumbs or baby food can be effective lures to draw cockroaches out of their nests and into your traps. You can also use peanut butter – and dipping pieces of bread in beer has also been shown to be an especially enticing lure for cockroaches.
Generally speaking, roach bites may be a nuisance, but they are not dangerous. Unlike mosquitoes, ticks, and other insects, roaches do not transmit diseases through their bites. They do, however, carry germs and bacteria that they can spread wherever they travel, so it's best to get rid of them as quickly as possible.
Each species of cockroach has their own estimated lifespan but on average, cockroaches live for about one year. Factors such as food supply, habitat and climate affect lifespan. American cockroaches can live for about one year while German cockroaches are estimated to live for about 100 days.
