How Long Do Cockroaches Live? All cockroaches go through three stages of life: egg, nymph, and adult. While these insects usually live about 6 to 15 months, the cockroach lifespan varies based on species, moisture, and temperature in each of these phases.
Cockroach feces are easy to identify. Droppings from small cockroaches resemble ground coffee or black pepper. Larger roaches leave behind dark, cylindrical droppings with blunt ends and ridges down the side.
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.
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.
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.
Check your mattress
Again, it's uncommon for roaches to be found on mattresses, but it's not uncommon for them to hide in your bed frame and bedside furniture. When you remove your mattress and dismantle your bed to move, check for signs of cockroaches and remove or sanitize items as necessary.

Citronella
Citronella not only works great for repelling mosquitos but also cockroaches. While the candles don't work well against roaches, you can use citronella oil as a deterrent. You can mix it with water and use it as a spray or simply wipe down areas with the diluted mixture.
The fact is that while good sanitation methods alone rarely prevent cockroach infestation, employing scrupulous levels of cleanliness will go a long way toward controlling the problem. (It will also help you get rid of mites, ants and other pests.)
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.
