Cockroaches hate smells of things such as bleach, cinnamon, bay leaves, garlic, peppermint, and coffee grounds as well as tea tree oil and eucalyptus oil.

Cockroaches do hate the smell of bleach.

Household bleach is commonly used as a cleaning agent and gives off a strong smell that cockroaches hate.

Because of this smell, cockroaches will just scurry away from the trap instead of getting tempted to drink it.

Killing a cockroach does attract more cockroaches if you kill the cockroach with force such as by squishing the cockroach because when you squish the cockroach it releases a pheromone which is a smell that the other cockroaches can detect.

The other roaches pick up the smell of the pheromones and reach the food source.

The male roaches discharge pheromones during the mating season to attract females.

So, when you kill a roach by crushing it under your shoes, it's glands bust and all the guts, fats, and, most importantly, the pheromones splatter out.

Smells that keep roaches away include bleach, Lysol and peppermint oil, cedarwood oil, and cypress oil.

Cockroaches are not afraid of much but if they see humans they will try to scurry away or if they see an animal they will usually scurry away too.

Contrary to popular belief, cockroaches are not afraid of light.

Although most species do prefer darkness, some are actually attracted to light and can be found gathering near windows or on television screens at night.

However, this reaction is much more influenced by their fear of humans than their distaste for light.

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.

The best way to get rid of roaches overnight is to set off roach foggers in the home and then leave the home for the night.

The roach fogger will kill the roaches overnight while you're away from your home and then when you return the  next day you can clean the dead roaches up.

You can also place out sticky traps to catch and kill roaches and also use duct tape to make sticky traps or use some Borax which kills roaches.

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.   

You can also hire an exterminator to get rid of the roaches for you too.

To find a cockroach nest look behind things in your home such as behind refrigerators, in kitchen cabinets, crawl spaces, in corners and other compact places.

The common telltale signs of a cockroach nest include mounds of cast skins, egg cases, dark spots or smears and live or dead cockroaches.

Egg cases of cockroaches can even be found on the underside of your furniture.

The cleaner that cockroaches hate the most is bleach as well as Lysol cleaner.

The smell of the Lysol and Bleach will repel and keep cockroaches away and also keep your home clean and disinfected with prevents roaches in your home.

For roach deterrents, cockroaches dislike the smell of cinnamon, bay leaves, garlic, peppermint, and coffee grounds.

If you want a strong-smelling disinfectant, choose vinegar or bleach.

The best scent-based deterrents are essential oils, such as eucalyptus or tea tree oil.

Roaches are attracted to urine as they like the smell and also the fact that urine contains water which the roaches are also attracted too.

Cockroaches are attracted to anything that they can feed on.

Urine has a strong, pungent smell, and about 91 to 96 percent is water, which can attract cockroaches and other pests.

They can attract germs through urine and later contaminate your food.

Vinegar can attract roaches but the vinegar does not actually kill the roaches or repel the roaches.

Using vinegar can keep your home clean though to prevent roaches.

The color of light that roaches hate the most is red light.

Although roaches hate other light colors which include yellow light, green light, blue light and sometimes white light.

To lure or get a cockroach out of hiding and catch then take some sticky traps and place some food onto the sticky traps.

The cockroaches will then come out of hiding and walk onto the sticky trap and get stuck.

Give the roach what it wants – food and moisture.

Put some roach bait on the food or place the food on a sticky cockroach paper.

Spread a mixture of minced onion and boric dust.

Spread a mixture of sugar and borax.

Cockroaches can and do sometimes crawl on you at night and may even crawl in your ear.

Also cockroaches like to go around during the night, which coincidentally is when people sleep.

So by virtue of just lying there motionless, we become likely victims.

Cockroaches also like small, warm, humid places.

The problem is that once the roach crawls inside the ear, it's likely to get stuck.

Cockroaches do die in freezing temperatures.

Cockroaches can only survive temperatures above 15 F degrees before they die after being exposed to the 15 F or 0 F degrees for a prolonged period of time.

If you've tried other methods and still have a roach infestation then moving somewhere else for the entire winter and shutting the heat off to the home can kill the roaches.

If you have a house that has cockroaches in it you can shut the heat off and also the water and then allow the house to remain at freezing temperatures for a few months.

It takes prolonged cold temperatures to kill the cockroaches but it can work.

Humans are afraid of cockroaches as cockroaches spread germs and diseases and even urine and fecal matter which can also contaminate food.

Also the speed of the cockroach can cause some humans to be afraid of them as anything which can move faster than humans can will trigger a humans fear response because of our ancestors need to outrun any hungry predators.

The sound that attracts cockroaches is a wing fanning sound at a rate that equals to or less than 12 to 10 seconds of trains of wing fanning events per hour.

Cockroaches cannot really survive a nuke although they are hard to kill.

Any species of cockroaches would die from a direct nuclear bomb blast and if the radiation does not kill them, then the heat and the impact of the nuke blast certainly would kill the cockroaches.

Cockroaches are not attracted to light as they prefer to be out at night.

Although you can still see cockroaches out during the daytime as well but they are mostly nocturnal and light itself does not attract cockroaches.

However moisture, water, food, dog food, crumbs, trash etc all attract cockroaches.

The LED light colors that attract bugs are white color LED lights as well as coo white blueish color.

Yellow led lights or yellow lights in general tend to fend off bugs and they are not as attracted to the yellow bulbs as other lights.

The insect that flies around lights at night are moths.

Although some other insects such as gnats and flies and sometimes mosquitoes will fly around lights at night as well.

The little bugs that are attracted to light are called gnats as well as beetles, crane flies and even flies.

Though the little bugs you most often see around lights are gnats.

Most insects are attracted to light.

In reality though all bugs are attracted to light because it's a way to escape from predators although some bugs are not as attracted to light as others.

Like a moth to a flame, er, lamp, insects are also drawn to bright lights because they confuse the animals' navigational systems.

It's a familiar sight, especially in the summertime: moths and other insects gathered around lights like lamps.

Often, creatures entranced in such a glow get eaten by predators or overheat

Bugs that light attracts are gnats, moths, flies, mosquitoes, grasshoppers, beetles, German cockroaches, brownbanded cockroaches, American cockroaches and Turkestan cockroaches.

Most bugs are attracted to light and will seek the light.

LED lights do attract bugs.

However since LED lights don't put out UV light or as much heat as regular light bulbs the LED bulbs don't attract bugs as much as the regular light bulbs do.

LEDs are not as warm as other light bulbs, so they're actually less likely to be attracting insects and spiders.

If you've noticed the presence of insects near your strip lights, take some time to clean the area and use repelling products like citrus and cedar-scented sprays.

The theory for why insects are attracted to light is that, in the wild, light signals an escape from potential danger for insects.

When an insect sees light, it can tell them that a path is not blocked by a predator or obstacles.

Yellowish, pinkish, or orange (sodium vapor, halogen, dichroic yellow) are the least attractive to most insects.

When white incandescent bulbs were all that was available, the advice was to change them to yellow incandescent bug bulbs.

LED bulbs are less attractive to bugs because they produce low heat and long wavelengths of light.

Moreover, they produce little or no ultraviolet radiation.

It makes them perfect for outdoor lights for events and around the home.

The best option is going to be a yellow compact fluorescent light (CFL).

Yellow is the point where the wavelengths start getting longer. CFLs offer the best energy efficiency and emit less heat.

Other yellow-tinted light bulb options that go unnoticed by insects include sodium vapor and halogen bulbs.
