Does Killing a Cockroach Attract More? 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.
Dead cockroaches attract more roaches by secreting a chemical called oleic acid. This acid releases a “Death Stench,” which alerts other cockroaches that one of them is down. That substance released from the roach's corpse is a fatty acid, a good source of food for them.
Soapy water A lot of people don't know this, but using soapy water can be great when you want to kill roaches. You can spray them with soapy water and this will suffocate them. The focus here is to create a thin film of soap around the roach's body and that will suffocate him.
Seeing dead cockroaches can mean two things. Either there is a heavy infestation, or the infestation is dying out. Since roaches come out at night, not all make it back to their nest alive. Therefore, you are most likely to find lifeless roaches around your house in the morning.
While disappearing dead cockroaches may seem like it should be an episode of the twilight zone, there are perfectly good explanations for why this happens. There are a few reasons why these cockroaches seem to disappear, including being eaten by other insects, not really being dead, or being moved by a breeze.
And when they detect the smell, they come looking for their dead counterpart. Having dead roaches in the home is a surefire way to attract an additional cockroach infestation. So, getting rid of the dead roaches, and treating live ones, is the only way to rid your home of these gross insects.
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.
The different body parts, waste, and saliva of cockroaches are allergens for certain individuals. Even dead cockroaches can still cause some allergic reactions. Therefore, it is not advisable to step on a cockroach, as its crushed body parts can trigger some allergies.
Inside their bodies, cockroaches contain a white substance known as fat bodies. Similar to fat stores in humans, fat bodies allow cockroaches to store energy after nutrients have been broken down.
How Long Do Roaches Live; Or, WHEN DO THEY DIE? The average lifespan of a cockroach is about 1.5 years. But their lifespan depends heavily on food and water availability, climate and habitat. Some roaches freeze.
The World Health Organization also advises against crushing them, for reasons of hygiene. According to the body, which classes cockroaches as “unhygienic scavengers in human settlements”, squashing them can spread bacteria into the environment that can lead to asthma, allergies and illnesses.

Cockroaches have extremely strong and flexible exoskeletons, which make them almost impossible to squish, withstand the hardest stomp or the toughest newspaper. They can also flatten themselves to fit into tight spaces and crevices, making for an easy getaway.
Cockroaches are attracted to food and water sources. Dirty dishes, crumbs, food spills, leftovers, garbage, and pet food will all draw cockroaches in. Roaches are excellent at scuttling into and over tiny spaces, especially holes in pipes, cracks and crevices in your home, and tears in screens.
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.
We've recently heard a rumor that squishing a cockroach is a bad idea because it could spread the insect's eggs around, making more baby cockroaches. "The crushing in itself doesn't really spread eggs," said Louis Sorkin, a scientist in the entomology department at the American Museum of Natural History.
Cockroach eggs look like small tan, brown or black capsules shaped something like a pill or a purse. German and American cockroach eggs are approximately 1/3-inch (8 mm) long, while those of the Oriental and SmokyBrown cockroaches are slightly longer, reaching lengths of almost ½ inch (12 mm).
You'll know you've found a pregnant roach if it appears to have a pill-shaped protrusion sticking out like a fat, ribbed tail. This extends further as more eggs develop inside it. The “pregnant” female carries her egg case for about 1 month until the eggs are ready to hatch.
The real cause of a cockroach's white appearance is that when roaches molt, they don't only shed their outer shell, they also lose most of the pigmentation in their bodies, which must then be replaced. This is a chemical reaction that occurs within the body, usually taking a few hours to fully restore pigmentation.
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.
And if the roach is big—say, 1 1/2 inches or bigger—it could be an outdoor species that's less likely to thrive indoors. The problem is that even if it is all alone, it could be a pregnant female, or the first of a colony that's living right outside your home.
Smells that roaches hate: a quickfire summary
Oregano, rosemary, mint, eucalyptus, lemongrass and catnip are great herby options. Citrus oils work brilliantly too.
Roach Repellents
Peppermint oil, cedarwood oil, and cypress oil are essential oils that effectively keep cockroaches at bay. Additionally, these insects hate the smell of crushed bay leaves and steer clear of coffee grounds. If you want to try a natural way to kill them, combine powdered sugar and boric acid.
Because of this, cockroaches will not bite active humans, but sleeping humans is another matter. Cockroaches emerge from their indoor hiding spots at night to seek out food, and while doing so, they sometimes crawl over sleeping humans.
