Moisture. Roaches need moisture to survive and this search for water will bring them into even the cleanest of homes. Leaky pipes and faucets are one of the most common attractants for cockroaches and is one of the main reasons you often see them in bathrooms, kitchens, and laundry rooms.
1. Moisture. Roaches prefer dark, moist environments. Any source of water or moisture can be a potential lure, including leaky pipes under a sink, damp basements, leaky air conditioner units, roof leaks, standing water and even piles of wet leaves outside your home.
What attracts American cockroaches is decaying, organic matter (i.e. garbage) as well as moisture. If you're seeing a large number of American cockroaches, it may be an indication of a plumbing issue. For example: There may be a crack in the sewage line under your house or in your building's basement.
Eliminate Their Water Sources
If you have any wet towels or sponges, put them in an airtight bag overnight. Leaving them on the counter can attract roaches. You should also empty your pets water bowls every night and refill them every morning. Leaving out a bowl of water is an open invitation for cockroaches.
The best way to keep cockroaches away permanently is to make the home less inviting. Make sure to keep the home clean, clean up food messes, take out trash at the end of the day, seal any cracks or gaps around windows, doors and the foundation, and fix any issue that might lead to high moisture content within the home.
If you spot one, odds are there are a few others lurking nearby, in dark corners or cracks and crevices and they could be fast on their way to a full blown infestation. Cockroaches are dangerous to humans – they carry bacteria on their bodies and their feet, contaminating any surfaces they come into contact with.
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.
Crumbs, spills, and food that has been left out are a great way to end up with a roach infestation quickly. The key to keeping roaches out is to keep your home, but most importantly your kitchen, as spotless as possible. After cooking or preparing a snack, wipe up crumbs and spills immediately.
Sugar. 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.

Temperatures between 15 and Zero degrees Fahrenheit will kill a cockroach, and they cannot breed at temperatures below 40 degrees. So, once temperatures start to drop, roaches look for a warm place to hide.
Taking a deep drink of household bleach would kill anything, roaches included. But the same strong odor that keeps people from taking a swig of bleach repels roaches as well. So though it could work, in reality, it will not. It is very difficult to kill an entire roach infestation yourself.
Squashing a cockroach can spread disease
The World Health Organization also advises against crushing them, for reasons of hygiene.
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.
Thus, sleeping with the light on can keep cockroaches away from your bedroom. When you leave your lights on, the cockroaches will not even try to come out. Predators are also attracted by the light and will begin to actively hunt down the cockroaches when it's bright in the room.

In most situations, cockroaches would not bite humans if there are other food sources such as in garbage cans or exposed food.
Females have an estimated adult lifespan of 180 days, while males have an adult lifespan of about 160 days. Cockroaches are one of the oldest living insects on the planet. Their life cycle plays an important role in their ability to survive and populate the earth.
