It is OK if a cockroach touches you as cockroaches are basically harmless and do not bite although they can spread fecal matter and urine and other contaminates onto your skin.
So if a cockroach does touch your skin you should wash that skin off with some soap and water to get rid of the bacteria and germs.
Cockroaches do not feel any pain when sprayed or crushed as they don't have the pain receptors like humans and other animals have.
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.
